Update: The gunman has been identified as Myron May, who fired a semiautomatic .380 caliber handgun, which he reloaded at least once

At 12:30 a.m. a Florida State alumnus and attorney walked into the Florida State library, which was reportedly packed with three hundred students prepping for end-of-semester exams, and opened fire. The gunman left three people wounded before police shot and killed him.

Police were able to stop the gunman after he was confronted outside of the library and ordered him to drop his weapon. He refused and fired a shot at the officers, which led to police firing back, Tallahassee Police spokesman Dave Northway says.

The Washington Post reported that one wounded student could be seen crying out that he had been shot while clutching a bloody leg.

One person is in critical condition and another reported in good condition, while the other victim was released.

Police and FSU officials told the Associated Press that this was an “isolated incident” but have not released many details about the shooter or possible why the shooting happened and how he was able to get onto campus.

FSU sent out an alert after the shooting began, it read: “*FSU ALERT!* Dangerous Situation! Main Campus-Tallahassee, seek shelter immediately, away from doors and windows.”

At 4:15 a.m. an all-clear was given to the school, although classes were canceled for the remainder of Thursday while police continued to interview and investigate the situation.

Pictures and videos of the shooting now appear online, with students screaming, crying, and hiding in fear of the shooter.

Since the Sandy Hook shooting, there have been over seventy-four school shootings.
