She Thought She Found LOVE On Tinder — 3 Days Later, Only Her SCRUBS Were Found
…
They spent an evening at Melissa’s apartment, carefully selecting photos for her profile.
They chose a picture of Melissa in her scrubs at the hospital, smiling warmly at the camera.
Katie said it showed her caring nature and her dedication to her profession.
They added photos from hiking trips in the Rocky Mountains, showing Melissa in her element surrounded by nature.
There was a photo of her laughing with her golden retriever Bailey, a rescue dog she had adopted 2 years earlier.
For her bio, they kept it simple and genuine.
Saving lives by day, searching for adventure by night.
Katie thought it struck the right balance between serious and playful.
Melissa activated her profile on March 1st, 2023.
For the first 2 weeks, she swiped through profiles half-heartedly, not particularly impressed with what she saw.
Most men seemed to be looking for something casual, or their profiles were filled with gym selfies and generic quotes about living life to the fullest.
Melissa wanted something real, someone with substance and depth.
She was beginning to think online dating wasn’t for her when on March 15th, she matched with someone who seemed different.
His name was Derek Hoffman.
According to his profile, he was 34 years old, worked as a software engineer, and his photos showed an attractive man with dark hair and an easy smile.
In one picture, he was hiking on what looked like a mountain trail.
In another, he was kneeling next to a beautiful golden retriever, the dog’s tongue hanging out happily.
The bio was brief but appealing.
Recently moved to Denver from Seattle.
Love hiking, trying new restaurants, and my dog Cooper.
Looking for someone genuine to explore this amazing city with.
Melissa felt a spark of interest.
He seemed normal, stable, like someone who had his life together.
The fact that he loved hiking and had a dog immediately endeared him to her.
She sent him a message, keeping it casual.
Nice dog.
Golden retrievers are the best.
The response came within minutes.
Thanks.
Cooper is my best friend.
I see you have one, too.
What’s your dog’s name? They began chatting and the conversation flowed naturally.
Derek asked about her work and Melissa told him about being a pediatric nurse.
He seemed genuinely interested, asking thoughtful questions about her day-to-day responsibilities and what made her choose that specialty.
Derek told her he worked for a company called Techvision Solutions doing remote software development.
He explained that he had just moved to Denver a few months earlier for a change of scenery after going through a difficult breakup in Seattle.
Melissa could relate to that experience.
Over the next 3 days, they exchanged hundreds of messages.
They discovered they had similar tastes in music, both loving indie rock and folk.
They both enjoyed Italian food and had a shared obsession with true crime podcasts.
Derek mentioned he was listening to a series about unsolved murders in the Pacific Northwest, and Melissa recommended one of her favorites about cold cases in Colorado.
The irony of that particular detail would later haunt everyone who knew Melissa.
Derek seemed almost too perfect.
He was attentive without being overwhelming, funny without trying too hard, and he expressed genuine interest in getting to know her as a person rather than just seeing her as a potential romantic conquest when he suggested meeting for dinner on March 18th.
Melissa felt genuinely excited for the first time in months.
She told Katie about the upcoming date during their shift on March 17th, and Katie’s reaction was mixed with excitement and caution.
“That’s great,” Katie said while they were restocking medical supplies in one of the pediatric units.
“But you’re meeting him in public, right? You’re not going to his place or anything.
” “Of course not,” Melissa replied, slightly annoyed at the implication that she would be careless.
We’re meeting at Rioa downtown.
It’s a nice restaurant with lots of people around.
Katie nodded but continued to press the safety issue and you’ll share your location with me and check in every hour.
Melissa agreed to all of Katie’s conditions, understanding that her friend was just looking out for her.
They had both heard horror stories about online dating gone wrong.
They had both listened to enough true crime podcasts to know that meeting strangers from the internet carried risks.
But Melissa felt confident that Derek was who he said he was.
They had talked so much over the past 3 days that she felt like she already knew him.
His messages were thoughtful and genuine, never pushing for anything inappropriate or making her uncomfortable.
He seemed like a decent person who, like her, was just trying to find a meaningful connection in a world that increasingly felt superficial and disconnected.
March 18th, 2023, arrived with clear skies and unseasonably warm weather for early spring in Denver.
Melissa finished her shift at the hospital at 3:00 in the afternoon, drove home to her apartment, and spent 2 hours getting ready for the date.
She wanted to look nice without appearing like she was trying too hard.
She settled on dark jeans, a soft blue sweater that brought out her eyes, and minimal makeup.
She checked her appearance in the mirror multiple times, nervous butterflies fluttering in her stomach.
She hadn’t been on a first date in over 2 years, and the anticipation was both exciting and terrifying.
Before leaving her apartment, she texted Katie with her location and a promise to check in regularly throughout the evening.
Katie responded with multiple heart emojis and a warning to trust her instincts if anything felt wrong.
Rioa restaurant was located at 1431 Lama Street in downtown Denver, known for its upscale Spanish and Mediterranean cuisine.
Melissa arrived at 7:00 in the evening, exactly on time.
She stood outside the restaurant for a moment, taking a deep breath and steadying her nerves.
Through the large windows, she could see the warm interior filled with other diners, the soft glow of candle light on tables, and the bustling energy of a popular Friday night spot.
She walked inside and gave her name to the hostess, who informed her that Derek had already arrived and was waiting at their table.
Melissa followed the hostess through the restaurant.
her heart beating faster with each step.
And then she saw him.
Derek Hoffman was standing next to their table, smiling warmly.
He looked exactly like his photos, which was the first relief.
Melissa had heard stories of people using heavily filtered or outdated pictures on dating apps.
But Derek was exactly who he had presented himself to be, at least physically.
He was tall, probably around 6 ft, with dark hair styled casually and warm brown eyes.
He wore dark jeans and a button-down shirt, dressed nicely, but not overly formal.
When Melissa approached, he extended his hand for a handshake, which she appreciated.
Some men went in for a hug on first dates, which always felt presumptuous and uncomfortable.
The handshake was respectful, acknowledging that they were still essentially strangers despite their digital intimacy over the past 3 days.
“Melissa, it’s so great to finally meet you in person,” Derek said with genuine enthusiasm.
“You look even more beautiful than your photos.
” Melissa felt herself blush at the compliment.
“Thank you.
You, too.
I mean, you look like your photos, which is good.
She laughed nervously at her awkward phrasing, and Derek laughed along with her, immediately putting her at ease.
They sat down, and the conversation picked up right where their text messages had left off.
There was no awkward silence, no struggling to find things to talk about.
Derek asked about her shift at the hospital, and Melissa told him about a particularly challenging case involving a 7-year-old with complications from pneumonia.
Derek listened attentively, asking follow-up questions and showing genuine empathy for both Melissa and her young patient.
The dinner lasted 5 hours.
They ordered appetizers, entre, dessert, and multiple glasses of wine, losing track of time as they talked.
Derek was charming and engaging, telling stories about his work in software development, his move from Seattle to Denver, and his love of outdoor activities.
He talked about growing up in the Midwest, his close relationship with his mother, who had passed away from cancer 3 years earlier, and his desire to build a stable, meaningful life with the right person.
Everything he said resonated with Melissa.
She found herself opening up in ways she hadn’t expected, telling him about her own family, her passion for pediatric nursing, her dreams of maybe working internationally with doctors without borders someday.
Derek’s responses were thoughtful and supportive, never dismissive or condescending.
When Melissa mentioned that she had been single for 2 years after a difficult breakup, Derek nodded understandingly and shared his own story of heartbreak in Seattle.
His girlfriend of four years had cheated on him with a mutual friend, and the betrayal had left him devastated.
“Moving to Denver was about starting fresh,” he explained.
Looking back later, investigators and psychologists would analyze this first date in detail, identifying the subtle manipulation tactics that Derek, whose real name was Vincent Crawford, employed so effectively.
He was lovebombing Melissa, showering her with attention and affection, creating an intense connection in a compressed time frame.
He was mirroring her interests and values, making himself seem like the perfect match.
He was sharing vulnerable personal stories designed to create emotional intimacy and trust.
But in the moment, sitting across from Derek in that candle lit restaurant, Melissa simply felt happy.
She felt seen and understood in a way she hadn’t experienced in years.
When Derek walked her to her car at midnight, he asked if she would like to see him again.
“Melissa didn’t hesitate.
” “I would love that,” she said.
Derek suggested a hike the next day at Red Rocks Park.
Melissa agreed immediately, excited to combine two things she loved.
Being in nature and spending time with this intriguing man, they hugged.
goodbye.
And Melissa drove home with a genuine smile on her face.
She texted Katie as soon as she got back to her apartment.
Best first date ever.
He’s amazing.
Katie responded with celebration emojis, but also repeated her earlier warning.
Just be careful and keep me posted.
Melissa went to bed that night feeling hopeful about her future for the first time in a long while.
She had no way of knowing that the man she had just spent 5 hours with was not who he claimed to be.
Derek Hoffman did not work for Techvision Solutions.
He had never lived in Seattle.
His mother was not dead.
His golden retriever, Cooper, did not exist.
The man sitting across from Melissa at dinner was Vincent Crawford, a 36-year-old serial predator who had been hunting women through dating apps for 4 years.
He had studied Melissa for weeks before creating his fake profile, learning her routines, her vulnerabilities, her desires.
He knew exactly what to say to make her feel special and safe.
And he was already planning how he would kill her.
The next morning, Melissa woke up energized despite getting only 5 hours of sleep.
She had to work the morning shift at Denver Children’s Hospital, 7:00 in the morning until 2:00 in the afternoon.
She texted Derek from the hospital during her lunch break, confirming their plans to meet at Red Rocks Park at 3 that afternoon.
Derek responded immediately with enthusiasm.
Can’t wait to see you again.
Bring Bailey if you want.
Cooper would love to meet another Golden.
Melissa thought it was sweet that Derek wanted their dogs to meet.
It felt like a natural progression in getting to know each other, introducing the important beings in their lives.
She finished her shift and drove home to change into hiking clothes and pick up Bailey.
The Golden Retriever was excited as always, tail wagging enthusiastically at the prospect of an outing.
Melissa loaded Bailey into her 2015 Honda Civic and drove to Red Rocks Park, arriving at exactly 3:00 in the afternoon.
Red Rocks Park was a stunning natural area just outside Denver, famous for its dramatic red sandstone formations and outdoor amphitheater.
The hiking trails offered spectacular views of the surrounding landscape.
And on a beautiful March afternoon like this one, the park was filled with other hikers, joggers, and families enjoying the sunshine.
Melissa parked in the main lot and looked around for Derek.
She spotted him standing near the trail head, waving at her.
As she approached with Bailey on a leash, she noticed something that should have been a red flag.
Derek was alone.
No dog.
Where’s Cooper?” Melissa asked, trying to hide her disappointment.
Derek’s face fell with what appeared to be genuine regret.
“I’m so sorry.
I completely forgot he had a grooming appointment this afternoon.
I couldn’t reschedule it because they’re booked out for weeks.
I hope Bailey isn’t too disappointed.
” Melissa accepted the explanation, though something about it felt off.
If Cooper had a grooming appointment, wouldn’t Derek have remembered that before suggesting a hike where the dogs would meet? But she pushed the thought aside, not wanting to be suspicious or judgmental.
People forgot things sometimes.
It wasn’t a big deal.
They began hiking on one of the moderate trails, Bailey trotting happily beside them.
The conversation continued to flow easily, though Melissa noticed that Derek skillfully avoided certain topics.
When she asked about his family, he gave vague answers about having a sister somewhere on the East Coast, but not being particularly close with her.
When she asked about his apartment in Denver, he described the general area, Cherry Creek, but didn’t offer specific details or an invitation to visit.
When Melissa tried to take a selfie of the two of them with the red rocks in the background, Derek politely declined, saying he looked terrible and sweaty from the hike.
These small moments of evasion should have added up to a pattern of concerning behavior.
But Melissa was caught up in the excitement of a new connection.
She was also falling victim to something psychologists call confirmation bias.
She wanted Derek to be genuine, so she interpreted his behavior in the most charitable light possible.
What Melissa couldn’t have known was that Derek had carefully calculated every aspect of their interaction.
He never brought a dog to their second date because there was no dog to bring.
The Cooper in his Tinder photos belonged to a man in Austin, Texas named Michael Torres, whose entire dating profile had been stolen and repurposed by Vincent Crawford.
Derek avoided selfies because he knew that photos could be traced, reverse searched, and potentially connected to his real identity.
He was vague about his living situation because the address he had provided, 1523 Cherry Creek Drive, was not his actual residence.
It was a corporate rental unit that he had access through hacking into the building’s reservation system.
He would only have access to that apartment for a limited time, just long enough to execute his plan.
Despite these warning signs that Melissa missed or dismissed, the hike was pleasant.
They talked for 3 hours, climbing to scenic overlooks and discussing everything from their favorite books to their thoughts on current events.
Derek demonstrated knowledge about topics that interested Melissa, from healthcare policy to environmental conservation.
He asked about her goals and dreams, seeming genuinely invested in her answers.
By the time they finished the hike and returned to the parking lot, Melissa felt even more convinced that she had found something special.
As they said goodbye, Derek brought up the possibility of a third date.
“Would you want to come over to my place tomorrow night?” he asked.
“I’m actually a pretty good cook.
I could make us dinner, Italian, if you’re interested.
” Melissa hesitated for just a moment.
Going to a man’s apartment on a third date felt fast.
But then again, everything about this connection had moved quickly.
They had talked for 3 days straight before even meeting.
They had already spent 8 hours together between the dinner and the hike, and Derek had been nothing but respectful and genuine in all their interactions.
Plus, Melissa told herself she was a good judge of character.
She worked with people every day in the hospital, reading their emotions and intentions.
She would know if something was wrong.
She would sense danger if Derek was actually dangerous.
“I would love that,” Melissa said, sealing her fate with those four words.
Derek’s face lit up with apparent joy.
“Perfect.
Tomorrow at 8, I’ll text you the address.
” They hugged goodbye and Melissa drove home feeling excited about where this relationship might lead.
She called Katie on the drive, putting her on speaker phone to give her an update about the second date.
“It went great,” Melissa said enthusiastically.
“He’s even better in person than he was over text.
We hiked for 3 hours and just talked about everything.
He’s so easy to be with.
” That’s wonderful, Katie replied, though her voice carried a note of caution.
But did you say you’re going to his apartment tomorrow? Melissa immediately became defensive, anticipating Katie’s concerns.
Don’t start with the safety lecture.
I’ve known him three whole days now.
We’ve talked constantly.
I can read people, Katie.
I’m a nurse.
I know when something’s off, and there’s nothing off about Derek.
Katie tried to push back.
I just think you should meet in public a few more times before going to someone’s house.
You don’t really know him yet, no matter how much you’ve talked.
Melissa’s tone became sharp.
You’re the one who told me to try online dating.
You said I needed to put myself out there and take chances.
So, that’s what I’m doing.
Can you be happy for me instead of acting like I’m making a terrible decision? Katie backed down, not wanting to fight with her best friend.
You’re right.
I’m sorry.
I just worry about you, but I’m sure it will be fine.
Derek seems nice from everything you’ve told me.
Just please text me when you get there and check in during the evening.
Okay.
Melissa agreed to the safety protocols and they ended the call on good terms.
But Katie couldn’t shake the uneasy feeling in her stomach.
Something about the speed of this relationship and Derek’s reluctance to take photos bothered her.
But she told herself she was probably being overprotective.
After all, what were the odds that Melissa would randomly match with a dangerous person on Tinder? The odds, it turned out, were higher than either of them could have imagined.
March 20th, 2023, was a Monday.
Melissa worked another morning shift at Denver Children’s Hospital, 7:00 in the morning until 7:00 in the evening.
It was a long shift, 12 hours of caring for sick children and supporting worried parents.
By the time Melissa clocked out at 7:00, she was exhausted, but still excited about her dinner date with Derek.
She had changed out of her scrubs and into a casual dress she had brought from home, touching up her makeup in the hospital bathroom before leaving.
Katie found her in the locker room as Melissa was getting ready to leave.
“You look beautiful,” Katie said, then added with forced cheerfulness.
“Have a great time tonight.
Be safe.
Melissa hugged her friend.
I will.
I promise.
Stop worrying so much.
I’ll text you at 9:00 to let you know everything’s good.
Katie watched Melissa leave the hospital.
A sinking feeling in her chest that she couldn’t explain.
Later, she would tell police that she had an intuition.
Something bad was going to happen, but she hadn’t known how to articulate it without sounding paranoid or controlling.
She would spend years wondering if she could have said something, done something to prevent what happened next.
Melissa got into her Honda Civic and entered the address Derek had texted her that morning into her phone’s GPS.
1523, Cherry Creek Drive, Apartment 12B.
The drive took 20 minutes through evening traffic.
Melissa sent one last text to Katie at 7:43 in the evening, heading to his place now.
We’ll check in at 9:00 with a red heart emoji.
She arrived at the address at 7:50 in the evening.
The building was nice, an upscale apartment complex in the Cherry Creek neighborhood with a doorman and modern architecture.
Melissa felt reassured by the professional appearance of the building.
This confirmed Derek’s story about having a good job and living comfortably.
She parked in the visitor lot, checked her appearance one more time in the rear view mirror, and walked into the lobby.
The doorman, a middle-aged man named James Patterson, greeted her politely and asked who she was there to see.
Derek Hoffman in apartment 12B, Melissa said.
The doorman checked his computer and nodded, directing her to the elevators.
Later, James Patterson would tell police that he remembered a young woman matching Melissa’s description entering the building that evening around 8, but he had no clear memory of the man she was meeting.
This was unusual for Patterson, who prided himself on recognizing residents and their guests.
The elevator security footage would show Melissa entering alone, pressing the button for the 12th floor.
Then the footage cut out due to what the building management claimed was a technical malfunction.
This malfunction was not accidental.
Vincent Crawford had remotely disabled the cameras using skills he had developed during his years working in IT.
Melissa knocked on the door of apartment 12B at exactly 8 in the evening.
Derek opened the door with a warm smile, wearing a casual button-down shirt and jeans.
Come in,” he said, stepping aside to let her enter.
The apartment was tastefully decorated with modern furniture, soft lighting, and the smell of something delicious cooking in the kitchen.
Classical music played softly from a speaker in the living room.
It all seemed perfect, romantic, thoughtful, everything a woman could hope for on a third date with a promising new partner.
Derek offered Melissa a glass of wine, which she accepted.
He had already poured himself a glass, and they toasted to getting to know each other better.
Melissa took a sip of the wine, a nice red that tasted slightly bitter, but not unpleasantly so.
She attributed the bitter note to the wine varietal, not knowing that Derek had dissolved rohypnol, a powerful seditive commonly known as a date rape drug, into her glass.
They talked for about 30 minutes.
Derek asking Melissa about her day at the hospital while he finished preparing dinner in the kitchen.
Melissa began to feel strange.
The room seemed to tilt slightly.
Her thoughts became fuzzy around the edges.
She tried to stand up from the couch where she had been sitting, but her legs felt weak and unsteady.
“Are you okay?” Derek asked, his voice coming from far away despite him standing right next to her.
Melissa tried to respond, but her words came out slurred and incomprehensible.
She felt Derek’s hands supporting her, guiding her back to sit down.
“Just relax,” he said softly.
“You’re probably just tired from your long shift.
” Melissa wanted to argue, wanted to say this felt like more than just tiredness, but she couldn’t form the words.
The last thing she saw before losing consciousness completely was Derek’s face.
No longer warm and charming, but cold and calculating.
The mask had finally dropped, revealing the monster beneath.
When Melissa’s eyes closed, Vincent Crawford checked his watch.
8:47 in the evening.
right on schedule.
He had maybe two hours before Katie Morrison would start calling, wondering why her friend hadn’t checked in at 9 as promised.
That gave him plenty of time to complete his plan.
He picked up Melissa’s phone from where she had left it on the coffee table and powered it off.
Then he went to work, moving with practiced efficiency through the steps he had executed five times before.
At 9:00 in the evening, Katie Morrison checked her phone during a break in her evening shift at Denver Children’s Hospital.
No message from Melissa.
She texted her friend.
Everything okay? Just checking in.
The message showed as delivered, but not read.
Katie waited 30 minutes, trying not to worry.
Maybe Melissa was just caught up in a romantic moment and forgot to check her phone.
Maybe she and Derek were having such a good time that 9:00 came and went without notice.
But at 9:30, when there was still no response, Katie’s anxiety increased.
She called Melissa’s phone.
It went straight to voicemail.
Katie left a message trying to sound casual rather than panicked.
Hey, it’s me.
Just wanted to make sure you’re having a good time.
Call me when you get this.
By 10:00 in the evening, Katie’s concern had transformed into genuine fear.
She called again, straight to voicemail.
She sent multiple texts.
None of them showed as red, indicating Melissa’s phone was powered off.
This was completely unlike her friend.
Melissa was responsible and thoughtful.
She wouldn’t just ignore check-in messages after promising to stay in contact.
Katie’s mind raced through possibilities.
Maybe Melissa’s phone died.
Maybe she was in an area with no service.
Maybe she was so involved in her date that she genuinely lost track of time.
Or maybe something terrible had happened.
At 11 that night, Katie made the decision to call Melissa’s parents.
She hated to worry Robert and Linda Chen, but something felt desperately wrong.
Robert answered the phone, his voice groggy with sleep.
Katie, is everything all right? It’s the middle of the night.
Katie explained the situation as calmly as she could.
Melissa had a date tonight at a man’s apartment.
She promised to check in at 9:00, but never did.
Her phone is off.
I’m really worried.
Robert’s voice became instantly alert.
What man? Where? Katie provided all the information she had.
Derek Hoffman, the address on Cherry Creek Drive, the details Melissa had shared about meeting him on Tinder three days earlier.
Robert and Linda Chen were both wide awake now, sharing Katie’s fear that something bad had happened to their daughter.
At midnight on March 21st, Robert Chen called the Denver Police Department to report his daughter missing.
The officer who took the call was initially dismissive.
Adults are allowed to turn off their phones and not check in with their parents.
The officer said, “Is there any indication that your daughter is in danger or that a crime has been committed?” Robert tried to explain that this behavior was completely out of character for Melissa, but the officer remained skeptical.
In missing person’s cases, police are often hesitant to act immediately for adults who have only been out of contact for a few hours.
People have the right to their privacy, and many missing person reports turn out to be misunderstandings or adults choosing to disconnect temporarily, but Robert Chen was persistent.
My daughter is a responsible adult who promised to check in with her friend.
She would never break that promise without a reason.
Something is wrong.
I know it.
Please send someone to check the address where she went.
Finally, the officer agreed to send a patrol car to conduct a wellness check at 1523 Cherry Creek Drive.
Two officers arrived at the building at 1:00 in the morning on March 21st.
They spoke to the doorman, James Patterson, who confirmed that a young woman matching Melissa Chen’s description had entered the building around 8 the previous evening.
The officers went up to apartment 12B and knocked on the door.
No answer.
They knocked harder, announcing themselves as police.
Still no response.
The building manager was called to unlock the apartment.
When the door opened, the officers found the unit completely empty.
Not just empty of people, but empty of furniture, personal belongings, any sign that someone lived there.
The apartment appeared recently cleaned with the chemical smell of disinfectant in the air.
There was no food in the kitchen, no dishes in the sink, no indication that dinner had been prepared.
It was as if no one had been there at all.
The officers checked with building management who confirmed that apartment 12B was a corporate rental unit.
It had been vacant for the past 3 weeks with no scheduled rentals.
Someone had accessed the apartment without authorization, though the building’s digital key system showed no record of entry.
This was sophisticated.
Whoever had lured Melissa Chen to this location had the technical skills to hack into building security systems and leave virtually no trace of their presence.
The officers returned to their patrol car and called in their findings.
A young woman had entered the building and never come out, at least not through the front entrance.
The basement parking garage had multiple exits and security footage was being reviewed.
Melissa Chen’s car, a 2015 Honda Civic with Colorado license plate CDH4892, was found in the visitor parking lot.
The car was locked with Melissa’s purse still inside on the passenger seat.
Inside the purse, officers found her wallet, identification, credit cards, and $40 in cash.
What they didn’t find was her phone.
This discovery elevated the case from a possible voluntary disappearance to a likely crime.
A woman doesn’t leave her purse and wallet behind voluntarily.
A woman doesn’t abandon her car and disappear without taking her belongings.
Something bad had happened in apartment 12B, even if there was no visible evidence of violence.
By 2:00 in the morning, the case was assigned to Detective Sarah Ramirez of the Denver Police Department’s missing person’s unit.
Detective Ramirez was a 15-year veteran of the force, known for her tenacity and her ability to spot details others missed.
When she arrived at the apartment building and reviewed the initial findings, her instincts immediately told her this was more than a simple missing person case.
This was an abduction, carefully planned and expertly executed.
Detective Ramirez began by interviewing the doorman, James Patterson.
She showed him a clear photo of Melissa Chen that Robert Chen had provided.
Yes, that’s definitely the woman who came in around 8, Patterson confirmed.
She asked for Derek Hoffman in 12B.
I directed her to the elevators.
Did you see Derek Hoffman? What did he look like? Patterson struggled to remember.
That’s the strange thing.
I see a lot of people come and go in this building, and I usually remember the residence pretty well.
But I can’t picture the man she was meeting.
I don’t think I ever actually saw him.
Ramirez made a note of this.
Either Derek Hoffman had entered the building through a different entrance or he was skilled at avoiding notice.
She reviewed the building’s security footage personally, noting that cameras covered the lobby, the parking garage, and the hallways, but the elevator cameras had mysteriously malfunctioned between 7 and 11 that evening.
The footage showed Melissa entering the lobby at 7:50 in the evening, walking to the elevators and pressing the button.
Then nothing.
No footage of her on the 12th floor.
No footage of her exiting the building and no footage of any man matching a description of Derek Hoffman.
It was as if Melissa had been swallowed by the building itself, disappearing into a technological blind spot.
Detective Ramirez knew this was not a coincidence.
Someone with advanced technical knowledge had disabled those cameras at precisely the right time to hide their actions.
This suggested premeditation and sophistication far beyond typical crimes of opportunity.
By the time morning broke on March 21st, Detective Ramirez had assembled a team to begin a comprehensive investigation.
The first priority was accessing Melissa’s phone records and digital footprint.
Through her carrier, investigators were able to remotely track the last known location of Melissa’s phone.
The phone had been at 1523 Cherry Creek Drive until 8:47 in the evening when it was powered off.
The phone had not been turned back on since, and its current location was unknown.
Ramirez obtained a warrant to access Melissa’s Tinder account and found the conversation history with Derek Hoffman.
The messages confirmed Katie Morrison’s account of the rapid development of the relationship.
Hundreds of messages exchanged over 3 days, increasingly personal and intimate.
Derek Hoffman’s profile was carefully examined.
The photos were professional quality, showing an attractive man in his mid30s with a golden retriever in various outdoor settings.
The bio claimed he was a software engineer recently relocated from Seattle.
But when investigators ran reverse image searches on the profile photos, they discovered something disturbing.
The photos belonged to Michael Torres, a real software engineer living in Austin, Texas.
Torres was contacted by Denver police and confirmed that he had never used Tinder and had no idea his photos had been stolen and used to create a fake profile.
Someone had taken his pictures from his LinkedIn profile and Facebook page, neither of which had privacy settings enabled.
Torres was shocked and horrified that his image had been used to commit what appeared to be a serious crime.
With the real identity of Derek Hoffman unknown, Detective Ramirez focused on the phone number associated with the Tinder account.
The number was traced to a burner phone, a prepaid cell phone purchased with cash at a 7-Eleven convenience store located at 945 Broadway in Denver.
Security footage from the 7-Eleven was reviewed, but the footage quality was poor, and the buyer had worn a baseball cap and kept his face down, making identification impossible.
The phone had been purchased on March 10th, 2023, just 5 days before Derek Hoffman’s Tinder profile had matched with Melissa Chen.
This timing suggested that the profile had been created specifically to target Melissa or women like her.
The burner phone had only ever contacted one number, Melissa’s cell phone.
This level of operational security indicated someone with experience in avoiding detection.
By midday on March 21st, Melissa Chen’s disappearance was being treated as a critical missing person case with suspected foul play.
Her photo was circulated to all hospitals, morgs, and law enforcement agencies in Colorado and neighboring states.
An Amber Alert was considered, but did not meet the criteria since Melissa was an adult, and there was no confirmed abduction by a known suspect.
Still, the media was alerted and local news stations began running stories about the missing nurse.
Katie Morrison was interviewed by police and media, providing details about Melissa’s character and the events leading up to her disappearance.
She’s the most responsible person I know, Katie said tearfully to a local news reporter.
She would never just vanish without telling someone.
Whoever this Derek person is, he did something to her.
I know it.
Robert and Linda Chen made emotional pleas on television, begging anyone with information about their daughter to come forward.
They released home videos of Melissa from childhood, images of her graduating from nursing school, photos of her with her golden retriever, Bailey.
The community response was immediate and overwhelming.
Hundreds of people volunteered to help search for Melissa.
Flyers with her photo were posted throughout Denver.
Social media campaigns using the hashtagfind Melissa Chen began trending locally.
Denver Children’s Hospital released a statement expressing their hope for Melissa’s safe return and describing her as a valued member of their team who would be greatly missed.
But as the hours turned into days, hope for finding Melissa alive began to fade.
Detective Ramirez knew from experience that the first 48 hours were critical in missing person cases.
After that, the statistics became grimmer, and they had no leads, no suspects, and no idea where Melissa had been taken or what had happened to her after she entered that elevator at 1523 Cherry Creek Drive.
On March 22nd, search teams were organized to canvas areas around Denver, where a body might be concealed.
Red Rocks Park, where Melissa and Derek had hiked on their second date, was searched extensively.
K9 units trained to detect human remains were deployed.
The trails were walked by dozens of volunteers calling Melissa’s name, hoping against hope that she might be injured somewhere, unable to call for help, but still alive.
Cherry Creek Trail was searched.
City parks were searched.
Vacant lots and construction sites were checked, but there was no sign of Melissa Chen.
It was as if she had simply ceased to exist the moment she stepped into that elevator.
The case was featured on local news every night with updates on the investigation and renewed appeals for information.
Crime experts were brought on television to discuss the dangers of online dating and the sophisticated methods predators use to target victims.
Tinder released a statement expressing sympathy for Melissa’s family and pledging cooperation with law enforcement.
The company emphasized that they had safety features in place and encouraged users to meet in public places and tell friends their plans, but critics pointed out that these safety measures had not prevented what happened to Melissa Chen.
On the morning of March 23rd, 2023, everything changed.
Amanda Russell, a 41-year-old accountant, had a morning routine that she followed religiously.
Every day before work, she would go for a 5mile run on the trails around Chatfield Reservoir, a large body of water located about 30 minutes south of Denver in Littleton, Colorado.
The reservoir was surrounded by beautiful natural areas with well-maintained trails perfect for running, hiking, and enjoying nature.
Amanda had been running these trails for years and knew them well.
On this particular morning, she was running along a less popular trail near the water’s edge when something caught her eye.
A pile of fabric partially hidden in the brush near the trail.
As she got closer, Amanda realized with growing horror what she was looking at.
Medical scrubs, navy blue in color, crumpled and discarded among the rocks and vegetation.
But what made her blood run cold was the dark staining on the fabric.
Blood.
Lots of blood.
Amanda pulled out her cell phone with shaking hands and dialed 911 at 6:45 in the morning.
The dispatcher answered immediately.
911.
What’s your emergency? I’m at Chatfield Reservoir, Amanda said, her voice trembling.
I found I found bloody clothes on the trail.
Medical scrubs.
I think something really bad happened here.
The dispatcher kept Amanda on the line, asking for her exact location and advising her not to touch anything.
Amanda gave the address of the nearest road access point, 15241 Waterton Canyon Road in Littleton.
Within minutes, Littleton police were dispatched to the scene, and Detective Sarah Ramirez was immediately notified.
Ramirez arrived at Chatfield Reservoir at 7:30 in the morning, her stomach already tight with dread.
The location was isolated, exactly the kind of place someone would choose to dispose of evidence or a body.
Crime scene technicians were already setting up a perimeter around the area where Amanda Russell had found the scrubs.
Ramirez approached carefully, not wanting to contaminate the scene.
The scrubs were laid out on a tarp for examination.
They were navy blue, a common color for medical professionals.
There was a hospital logo on the pocket, Denver Children’s Hospital.
And there on a white name tag still pinned to the shirt were words that confirmed Ramirez’s worst fears.
Melissa Chen RN.
The scrubs were soaked in blood, far more blood than would come from a minor injury.
The fabric was torn in several places, suggesting a violent struggle.
Ramirez felt a wave of nausea and grief wash over her.
She had been hoping against hope that Melissa Chen would be found alive, that somehow this would turn out to be a misunderstanding.
But these scrubs told a different story.
They told a story of violence and murder.
The area around where the scrubs were found was immediately searched by multiple teams.
K9 cadaavver dogs were brought in to search for a body.
The reservoir waters near the location were searched by divers.
Helicopters with thermal imaging cameras flew over the surrounding area, but no body was found.
Just the scrubs, discarded like trash, left for someone to find.
Crime scene technicians collected the scrubs carefully, preserving every possible piece of evidence.
Blood spatter analysis indicated that the blood had been fresh when the scrubs were discarded, meaning Melissa had likely been killed very recently, possibly the same night she disappeared.
DNA testing was expedited with results expected within a few days.
Detective Ramirez knew the DNA would confirm what she already knew, that the blood belonged to Melissa Chen, but she was also hoping for something else.
If there had been a struggle, there might be DNA from the perpetrator as well.
A single strand of hair, a flake of skin under Melissa’s fingernails, a drop of blood from an injury sustained during the fight.
Any biological material left by the killer could potentially be the key to identifying and catching him.
At 9 in the morning on March 23rd, Detective Ramirez had the devastating task of visiting the Chen family home in Boulder to inform them of the discovery.
Robert and Linda Chen had spent the past 3 days in a state of suspended horror, hoping for good news, but preparing themselves for the worst.
When they opened the door and saw Detective Ramirez’s expression, they knew immediately that the news was not good.
Can I come in?” Ramirez asked gently.
The Chens led her into their living room, the same living room where Melissa had grown up, where family photos covered the walls and showed a happy, smiling girl growing into a beautiful young woman.
Ramirez sat down across from them and delivered the news as compassionately as she could.
We found Melissa’s scrubs this morning at Chatfield Reservoir.
The scrubs had significant blood on them.
We’re still searching the area, but I need to prepare you for the likelihood that Melissa may not be coming home.
Linda Chen’s scream of anguish was something Ramirez would never forget.
Robert Chen sat in stunned silence, his face going pale as the words sank in.
Both parents began crying, clinging to each other as their worst nightmare became reality.
Ramirez stayed with them for an hour, answering their questions as best she could and connecting them with victim services support.
She also called Katie Morrison to come be with the family during this horrific time.
When Katie arrived and was told about the scrubs, she collapsed on the floor, sobbing.
She immediately recognized the specific coffee stain on the pocket of Melissa’s scrub top.
A stain from 3 days ago when Melissa had accidentally spilled her morning coffee before their shift.
That small detail, that coffee stain, confirmed beyond any doubt that these were the scrubs Melissa had been wearing at work on March 20th, her last shift before meeting Derek Hoffman.
The news broke to the media quickly.
By noon, every local news station was running the story.
Missing nurses, bloody scrubs found at Chatfield Reservoir.
The story was picked up by national media outlets within hours.
Cable news channels ran segments about the case, bringing on experts to discuss online dating safety and the psychology of predators who use dating apps to find victims.
Tinder’s stock price dropped as parents and partners expressed concern about the safety of the platform.
The hashtag find Melissa Chen evolved into justice for Melissa Chen.
True crime communities on Reddit and Tik Tok began their own investigations, analyzing Melissa’s Tinder profile, trying to find clues about who Derek Hoffman really was and discussing similar cases of women who had disappeared after meeting someone from a dating app.
The search around Chatfield Reservoir intensified over the next 2 days.
The area within a 15-mi radius was systematically searched.
Divers spent hours in the cold water looking for a body weighed down at the bottom of the reservoir.
Helicopters with thermal imaging cameras surveyed the area from above.
Hundreds of volunteers walked the trails, looking in the brush and the woods for any sign of Melissa, but no body was found.
It was as if the killer had made Melissa’s body disappear completely, leaving only her scrubs behind as evidence that she had been murdered.
This suggested the killer was organized, experienced, and knowledgeable about how to avoid detection.
He had disposed of the body in a location that would not be easily found.
while leaving the scrubs in a more accessible location to taunt law enforcement.
This behavior pattern was consistent with serial offenders who enjoyed the psychological game of cat and mouse with police.
By March 25th, the FBI officially joined the investigation.
Federal resources were brought to bear on the case, including behavioral analysts, forensic experts, and investigators with experience in hunting serial predators.
The involvement of the FBI indicated that authorities believed this was not an isolated incident, but potentially part of a larger pattern of crimes.
Detective Ramirez met with FBI special agent Marcus Webb, who had been assigned as the lead federal investigator on the case.
Webb was in his mid4s with 15 years of experience tracking down violent criminals.
He reviewed all the evidence collected so far and came to the same conclusion Ramirez had already reached.
Whoever did this has done it before.
Agent Webb explained his reasoning.
The level of planning, the use of a fake profile with stolen photos, the burner phone purchased with cash, hacking into building security systems, the careful disposal of evidence.
All of this requires experience and sophistication.
Firsttime killers don’t operate with this level of precision.
This is someone who has refined his methods over multiple victims.
The FBI’s behavioral analysis unit was consulted to develop a psychological profile of the unknown subject.
Based on the evidence and the methods used, they described the perpetrator as a white male between the ages of 30 and 45, likely living alone with above average intelligence and strong technical skills in computers and digital systems.
He would be socially skilled enough to appear normal and charming in person, able to quickly build rapport with potential victims.
He would have a history of controlling and manipulative behavior in relationships.
He would likely have a collection of trophies from previous victims, items he kept to relive the experience of his crimes.
And most importantly, he had probably killed before and would kill again if not stopped.
With this profile in mind, the FBI began cross-referencing missing person cases across Colorado and neighboring states.
They were looking for women who fit a similar pattern to Melissa Chen, professional women in their late 20s to mid30s who had disappeared after meeting someone through an online dating platform.
What they found was deeply disturbing.
Five other women in the region had disappeared under similar circumstances over the past four years.
Jessica Turner, 31, a marketing manager from Fort Collins, Colorado, had disappeared in June of 2019.
She had told her roommate she was meeting someone she had connected with on Bumble.
She was last seen getting into her car to drive to a first date.
Her car was found abandoned 2 days later in a parking lot.
She was never seen again.
The only evidence ever found was her jacket discovered near Horsetooth Reservoir 3 weeks after her disappearance.
Brittany Walsh, 28, a parallegal from Colorado Springs, disappeared in November of 2020.
