ORLANDO, Fla. (AP) — A college student with two guns, hundreds of rounds of ammunition and a backpack filled with explosives pulled a dorm fire alarm Monday in what may have been an attempt to force other students out into the open so that he could slaughter them, authorities said. But he instead put a bullet in his head as police closed in.

James Oliver Seevakumaran, 30, was found dead in his dorm room at the 51,000-student Orlando campus of the University of Central Florida. No one else was hurt.

"His timeline got off," university Police Chief Richard Beary said. "We think the rapid response of law enforcement may have changed his ability to think quickly on his feet."

Some 500 students were evacuated from the building in the middle of the night, unaware how narrowly they had escaped what could have been another Virginia Tech-style bloodbath.

Police shed no light on a motive, but university spokesman Grant Heston said that before the episode, the school was in the process of removing Seevakumaran from the dormitory because he hadn't enrolled for the current semester. He had never been seen by university counselors and had no disciplinary problems with other students, Heston said.

Detectives found notes and other writings that indicated Seevakumaran had carefully planned an attack and "laid out a timeline of where he was going to be and what he was going to do," Beary said.

The episode began when Seevakumaran pulled a gun on his roommate, who called police and holed up in a bathroom, Beary said. Around the same time, Seevakumaran pulled a fire alarm, apparently to get other students out in the open, the police chief said.

In his room, police found four makeshift explosive devices in a backpack, a .45-caliber handgun, a .22-caliber tactical rifle, and a couple of hundred rounds of ammunition, police said.

Antonio Whitehead, 21, said he heard the fire alarm go off in the dorm and thought it was a routine event.

"All of a sudden, I felt the crowd move a little faster. And a police officer with a machine gun or something told everyone to start moving a lot faster," he said.

Seevakumaran had attended the university from 2010 through the fall semester as a business student. His roommates told detectives that he had shown antisocial behavior but had never expressed any violent tendencies, Beary said.

According to Florida records, his only adult arrest in the state was in 2006 for driving with a suspended license.

Morning classes were canceled, but most campus operations resumed around noon.
