Frank DeAngelis was serving as Columbine High School's principal when a pair of students killed 13 people and themselves. DeAngelis vowed to stay in that job until every child in the district who wanted to graduated from Columbine. With that promise fulfilled, Frank DeAngelis is now ready to retire. He spoke to Anderson about the recent string of school shootings and how he handled the job for the last 15 years.
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.
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.
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.
Anderson Cooper goes beyond the headlines to tell stories from many points of view, so you can make up your own mind about the news. Tune in weeknights at 8 and 10 ET on CNN.
