Georgia shooting lasted about a minute after 26 teachers alerted authorities, sheriff says

Sayarath said the class started scrambling, many students rushed against the back wall of the room, others helped barricade the door by pushing desks against it, while some students called their parents.

Gray’s mother, Marcee Gray, called the high school Wednesday morning to warn a counselor of an “extreme emergency” involving her son, his aunt, Annie Polhamus Brown, told ABC News, after it was first reported in the Washington Post.

The Washington Post was the first to report on Marcee Gray’s alleged phone call with the school and obtained text messages between family members.
