Florida State University Shooting

While students were cramming for their midterms at FSU’s Stozier library, a gunman fired multiple shots, hitting three students, reported the Tallahassee Democrat. In an effort to protect themselves, other students hid behind rows of books or barricaded themselves inside study rooms.

“This person for whatever reason produced a handgun and then began shooting students in the library,” Florida State University Police Chief David Perry said, according to The Washington Post.

The gunman was shot and killed by Tallahassee police on an access ramp outside the library. Despite calls from police to drop his weapon, the gunman fired. In response, the police fired back.

“He was challenged by the officers and given commands to drop his weapon, but the male fired at the officers,” said a police statement. “The officers returned fire, killing the gunman.”

One of the wounded students was treated at the scene. The other two victims were transported to Tallahassee Memorial HealthCare, where one remains in critical condition while the other is reported in good condition.

On Thursday morning, Florida Governor Rick Scott arrived on the FSU campus to address the student body.

“I know every Seminole has the heart of a dreamer and every dreamer is resilient,” Scott said, reported the Democrat. “It’s very important to talk about what happened.”

As for FSU president John Thasher, he noted that thanks to the quick work of FSU PD and Tallahassee Police Department, the shooting wasn’t as bad as it could have been, stating, “Their training obviously showed up and helped defuse a situation that could have been worse.”

The identity of the lone gunman has not yet been released.
