In an exclusive interview, Arabo "BK" Babakhani tells Anderson Cooper what happened when his roommate at the University of Central Florida, James Oliver Seevakumaran, confronted him with a gun before Seevakumaran took his own life.
Babakhani immediately slammed and locked the door and called 911. "I was definitely scared, but calm, I was just taking cover in my room behind objects ... so that if he did fire, he wouldn't be able to hit me" he says.
By the time law enforcement arrived and raided the dorm, the 30 year old was dead.
Throw down some drinks at The Mad Hatter bar in Orlando? Check.
Pull the fire alarm, so about 500 students in Tower 1 on the University of Central Florida campus rush outside, together? Done.
Give them hell?
Those three words were the last item of James Oliver Seevakumaran's checklist that he made before, authorities say, he would go out with up to 1,000 rounds of ammunition and start shooting, possibly setting off bombs in the process.
It was not crossed off.
Instead of a mass killing early Monday morning, police reported only one fatality: Seevakumaran.
In the wake of a shooting at Lone Star College in Houston, Rep. Sheila Jackson Lee and Texas State Sen. Dan Patrick debate a proposal that would permit concealed guns on campuses in Texas.
Amanda Vasquez describes the panic she and other students at Lone Star College experienced during a shooting on the Houston, Texas campus.
Police say the suspected gunman in the shooting rampage at Oikos University was on the hunt for a female administrator at the school. When One L. Goh, 43, couldn't locate his target, he went after others at the small college.
Oakland, California Police Chief Howard Jordan said, "This was a calculated, cold-blooded execution in the classroom." After shooting a receptionist in front of students, Goh demanded they lineup so he could kill them. The attack left seven dead and three wounded.
Goh allegedly fled the scene in a victim's car as police searched the school. He surrendered to authorities at a supermarket after telling the security guard he needed to speak with police. Police Chief Jordan told CNN's Dan Simon that Goh does not appear remorseful about the killings.
Seven people died and at least two others were wounded in a shooting at a California college. CNN's Dan Simon reports.
Dina Parmertor, the mother of one of the teens killed in the school shooting at Chardon high school in Ohio, tells Anderson Cooper what she loved about her son's personality and how losing him has left her heartbroken. She also says that Danny was excited about recently getting his first job; as a symbolic gesture, she and her husband will place his first paycheck in his coffin.
Student Nate Mueller shares his experience caught in the shooting at Chardon High School in Ohio. He was grazed by a bullet before escaping the gunfire.
It started with an e-mail. In fact, it was the last of more than 600 e-mails CNN received in the wake of the Northern Illinois University shootings on Valentine’s Day. But this one stood out to me.

A frustrated and clearly anguished mother of a teenager was telling us she could relate to the massacre. That’s because her own son planned a school shooting when he was a high school junior in Idaho.
I immediately contacted Elaine Sonnen and spoke to her for at least an hour. I was immediately fascinated by her story - she saw the warning signs in her son, Richard, and was able to stop him from killing his classmates. But she still worried that he could be violent if he stopped taking his medication.
Still, there was little she could do because he was now over 18 and living on his own. She wanted to talk, but we knew the story would not be complete without hearing from Richard himself.
“Do you think he would talk to us?” I asked her. She agreed to call him and find out.
Program note: Tonight on 360°, CNN Special Investigations Unit Correspondent Abbie Boudreau has the second part of her exclusive interview with the girlfriend of Northern Illinois University shooter Steven Kazmierczak.
WONDER LAKE, Illinois - The girlfriend of the gunman who killed five people and then himself at Northern Illinois University last Thursday told CNN there was "no indication he was planning something."
"He wasn't erratic. He wasn't delusional. He was Steve; he was normal," Jessica Baty tearfully said in an exclusive interview.
Baty, 28, said she dated Steven Kazmierczak off and on for two years and had most recently been living with him.
