Florida State University is in shock following a shooting at the school's library early Thursday.
The shooter, identified as an FSU alumni and lawyer, shot three people, one of whom is said to be in critical condition.
The other two suffered only minor injuries.
The attacker was later shot and killed by police.
The shooting has taken place while hundreds of students were studying for exams in the library.
University officials say it remains unclear what sparked the shooting.
"We still have a lot of questions that are unanswered but police investigation will answer many of the questions we are asking today, but just like any tragedy the ultimate question of why will never have an answer that satisfies those whose loved ones have been injured or killed."
The FSU campus is located less than a mile from the state Capitol in Tallahassee.
