Orlando, FL (Florida Today) -- The former student behind an aborted attack plot at a Florida university was working off a checklist that included plans to get drunk, pull a fire alarm and then "give them hell," authorities said Tuesday.
James Oliver Seevakumaran was crossing items off his list ahead of his planned attack on classmates with guns and homemade explosives, University of Central Florida Police Chief Richard Beary said at a news conference.
The list found along with his dead body early Monday included drinking at a bar near campus and pulling the fire alarm - which investigators believe was meant to flush out victims. Beary says the final item was "give them hell."
Instead, Seevakumaran shot and killed himself as police officers arrived in response to the fire alarm and a 9-1-1 call from a roommate. Beary says authorities confirmed he had gone earlier to the bar and drank.
At the time of the attack, packages were waiting for Seevakumaran at a campus mailroom containing two 22-round magazines and a sling for his rifle and a firearms training DVD, officials said Tuesday.
Investigators have also said that they found an assault rifle, handgun, high capacity ammunition drums, hundreds of bullets and four makeshift explosives in a backpack near his body.
Beary said authorities still aren't aware of a motive or significant circumstance that led Seevakumaran to plan for an attack. The chief said no written explanation was left.
More details emerged Tuesday about Seevakumaran's solitary lifestyle. Seevakumaran's family said he was a loner who didn't have a history of violence in a brief statement released by authorities. Beary told the news conference that he acted alone.
"He didn't like to talk to people," Beary said.
The roommate who called 9-1-1 said Seevakumaran rarely left the dorm apartment, according to a dispatcher's notes. The caller also said Seevakumaran had pulled a gun on him.
In an interview with student publication Knightly News, Arabo "BK" Babakhani identified himself as the roommate who called 9-1-1.
Babakhani said Seevakumaran avoided eye contact, never had visitors to the dorm and never was seen talking to anyone on a cellphone.
"Instead of walking by me, sometimes he'll walk around me," the roommate said in an interview posted on the Knightly News website. "The only time he made solid eye contact with me is when he was pointing the gun at me."
Freshman mechanical engineer student Spencer Renfrow said when he would see Seevakumaran in the dorm's hallways and elevator, he would wave and Seevakumaran would wave back.
"Everything would seem fine," Renfrow said.
The business major, who held a job at an on-campus sushi restaurant, had never been seen by university counselors and had no disciplinary problems with other students, said spokesman Grant Heston.
