— Family and friends of a North Carolina Central University student killed by a security guard last month were protesting outside the security company’s building Friday afternoon.

DeAndre Ballard, 23, was shot Sept. 17 at his off-campus apartment at Campus Crossings in Durham.

Police have still not released the details of what happened that night, but the security company said the guard was acting in self-defense.

Ballard’s mother said she was told her son was trying to break into cars and got into a tussle with the guard prior to the shooting. She previously said she doesn’t believe that story, claiming her son was wearing only shorts and socks at the time, which is an indication he had briefly stepped out of his apartment to get something and was not up to mischief.

In a 911 call released Friday afternoon, the security guard who fired the weapon can be heard telling a dispatcher how the shooting unfolded.

"I see this guy, I'm in my car and I see this guy tried to get inside somebody else's car. I say, "Hey, man, what's going on?' He jumped inside my car, he started trying to fight me or whatever and tried to reach for my gun and so that's why I think I had shot him," the caller says.

In a second 911 call, a caller says Ballard was going in and out of consciousness as he sat propped up against the security booth at the entrance to the apartment complex following the shooting.

"He's going into shock. He's been shot in the abdomen. He tried to grab the officer's gun," the caller said.

The caller told the 911 dispatcher that Ballard was wearing a short-sleeved white shirt and long white pants at the time of the shooting, which contradicts the account given by Ballard's mother.

Friends and family believe there are many unanswered questions in Ballard’s death and held up signs across the street from the NC Detective Agency Friday. They said they want to hear what police say happened that night and want authorities to release the name of the security guard involved in the shooting.

“We want the name of the guard. If you’re so innocent and your killing was so justified, what are you hiding from? What are you afraid of? It’s not right, what happened to DeAndre, and what happens too often in the country and we want to shed light on that,” said Ballard’s friend, Alvarez Rodgers.

The NC Detective Agency said last month that the guard involved in Ballard’s death is state-certified and has 15 years of experience.

Records from the Private Protective Services Board show several violations for the NC Detective Agency's president, Roger Ladd. The violations are from 2010 to 2012 for failing to properly train guards and for falsifying training records.

The group said they will continue to protest until their questions are answered and additional protests are scheduled for this weekend.

Police haven't charged anyone in Ballard's death but said an investigation is ongoing.
