SARASOTA - The family of the student at UCF, who police say tried to carry out a mass killing, lives in Sarasota County.
Detectives found 30-year-old James Seevakumaran, dead of an apparent suicide. Next to his body, officers found guns, ammunition and a backpack of bombs.
Police say he pulled a fire alarm then went back to his room to pick up his weapons, when he ran into one of his roommates. That roommate ran into the bathroom and called 911.
A statement issued on behalf of Seevakumaran's family says that James was a loner, with no history of violence. They also requested privacy during a difficult time.

ORLANDO, Fla. (AP) -- 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 911 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 and didn't have any friends.
"He didn't like to talk to people," Beary said.
The roommate who called 911 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 911. He said he slammed the door on Seevakumaran after seeing the gun and hid behind furniture.
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."
Babakhani didn't immediately respond to messages left by The Associated Press.
AP reporters have also knocked on the doors of his mother and sister's homes, but no one answered.
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 university spokesman Grant Heston. Heston said that the school had been in the process of removing Seevakumaran from the dormitory because he hadn't enrolled for the current semester. He had attended the university from 2010 through the fall semester.
Some 500 students were evacuated from the dorm just after midnight Monday, and morning classes were canceled at the 51,000-student campus.
