Aaron Alexis, the gunman who killed 12 people during a shooting rampage at the Washington Navy Yard on Monday, was "obsessed" with violent video games, a new report claims.
A friend who lived with Alexis said he saw him playing "zombie" video games in his room, sometimes for up to 16 hours, until 4:30 a.m., which he believes may have contributed to a violent streak, the U.K.'s Daily Telegraph reports
"He could be in the game all day and all night. I think games might be what pushed him that way," said restaurant-owner Nutpisit Suthamtewakul, who met Alexis at a Buddhist temple in Texas. Suthamtewakul said Alexis also loved watching football on television.
He said Alexis had his .45 caliber handgun with him at all times.
"He always had this fear people would steal his stuff, so that's why he would carry his gun all the time. He would carry it when he was helping out in the restaurant, which scared my customers," he said.
Still, he described Alexis, a 34-year-old former Navy reservist, as having a "chilled" personality and as "a smart guy" for learning to speak Thai fluently during the time they lived together.
"He never got angry with us. He was always very nice to us. He had a couple of issues with being black. He felt he hadn't been treated right, not by the Navy, just generally. He didn't have a lot of friends — me, my wife and family, and people from temple," he said.
Alexis, he said, didn't have a grudge against the government.
Suthamtewakul recalled an incident in 2010 when Alexis was arrested for firing a gun in their home.
"It didn't go through the ceiling, it went through a wall. I was in the bedroom and I heard the gunshot. I jumped up and said, 'What the…' and Aaron came in and was really sorry. He said, 'I was cleaning my gun.' I said 'Put the safety on so you don't kill people in here.' He said 'I'm sorry, man.' It was just an accident."
Suthamtewakul's wife, Kristi, also described Alexis as "chilled," but recalled that he was angry about the Sept. 11 atrocities.
"I remember him talking about 9/11. He was there and when he came outside one of the buildings was gone already. All of a sudden the second building came down. He was an angry American, angry with the terrorists. I think maybe there was PTSD," she said.
"But he was very chilled. He loved Thai culture, Buddhist culture, he just loved to hang out and help out. He always had the gun tucked in his pants in the restaurant, but it didn't concern me because he had a license."
