But they say the shootout wasnt motivated by race. The victims just happened to be present at the moment in time when selis decided to carry out this spontaneous act of violence. There is zero information to indicate that race played a factor in this terrible and horrific crime. Reporter today Officials Say it was a breakup between selis and his girlfriend that may have triggered the rampage. This spontaneous act of violence. Reporter police say that as the shooting started selis used the other hand to dial his girlfriend. Ziftical ical sadistically making her listen to the spray of bullets and the screams that followed. Family members described selis as distraught and depressed over this breakup. Now, while they had no idea that he would resort to any kind of violence, let alone shooting at innocent victims, based on the information that we have gathered so far, investigators, it is very clear that selis was despondent over the breakup of his girlfriend. Reporter according to court documents, the 49yearold gunman was a car mechanic who had been struggling financially for years, filing for bankruptcy in 2015. I heard about five to six gunshots and now people are screaming. Reporter the chaos started just after 6 00 p. M. On sunday. Hes sitting in a lawn chair. He is telling people to leave. Reporter 911 calls began pouring in as selis started shooting into a crowd of some 30 people gathered for a birthday barbecue. Almost nobody thought that this was a gangrelated shooting because this is an upscale apartment complex full of professionals where even a studio apartment can go for 2,0 2,000.

White male, 40. Reporter others fled, but kayla and her friend said they felt they had no choice but to hunker down in the hot tub. Were you able to see any of the victims from where you were in the jacuzzi . Yeah, so i saw the woman lying face down on the floor with blood on her back. I saw another woman in a long black dress like all bloodied running out. I saw a man with a side wound, a side gunshot wound hopping over the fence. I think he felt. Reporter meanwhile, she says selis kept sitting calmly in his lounge chair. He was very discreet. He didnt draw any attention to himself. I didnt see him walk in. He was just sitting under an umbrella in the corner in the shade. He had a beer in one hand and his gun in the other. I didnt even realize that he had a gun until he started shooting. In that moment we were kind of frozen and we didnt have the initial flight fight or flight reaction. So we just stayed in the jacuzzi for a little bit. Reporter at around 6 13 the officers arrived on the scene with a chopper overhead. Directing the team on the ground, which confronted selis. They may have already known about the kind of threat they faced. My first takeaway of hearing information about this shooter being relaxed, drinking a beer or otherwise not concerned about the damage or the carnage that hes yielding on these crowds is that hes coldblooded, that he doesnt care about life, which ratcheted up the level for officers because someone like that will kill you just as soon as look at you. Reporter the gunman continued to fire his weapon. Police say that when selis raised his weapon at officers they fired. Well over a dozen shots. Shots fired. Suspect down. Shots fired. Suspect down.
