According to the Pierce County Prosecutor's Office, Pitts was dead, and Horton was laughing - having shot his victim in the chest and abdomen with a .45 caliber pistol before dragging him to the parking lot. Authorities say the murder was the result of gang bravado and a slap-boxing match gone wrong.
Prosecutors contend that Horton and Pitts were hanging out at the apartment of a friend when they got into a "heated discussion began regarding whose gang was better." Horton allegedly told authorities he is a Gangster Disciple from Chicago, while Pitts allegedly claimed allegiance to the Lakewood Hustler Crips.
As can apparently happen in such situations, the argument escalated into a slap boxing match. But the only trouble is, Horton got upset when he thought Pitts smacked him too hard.
So prosecutors say he opened fire. Witnesses tell authorities they heard shots and then saw Pitts stumble backwards and fall to the floor.
"This case highlights the senselessness of gang violence," says Pierce County Prosecutor Mark Lindquist in a press release distributed to the media announcing first-degree murder and possession of a firearm charges against Horton.
Horton is scheduled to be arraigned today at 1:30 p.m.
