Luis Gonzalez, 18, and two other teens are now in custody. The 18-year-old who died in the shooting has now been identified as Alejandro Vazquez.
Investigators say the gunman got out of a car in the area of Tulare and Wessmith Thursday night and shot Vazquez twice. The bullets also injured his twin brother and an eight-year-old girl. They're both recovering.
Vazquez's little sister says she witnessed the shooting. "He was a good brother, I was always there for him. When he had bad times, I was there for him. He shouldn't have died like that," said Rosa Vazquez.
Vazquez says her brother had tried to leave the gang lifestyle behind. Detectives believe he and the suspects were involved in an on-going dispute.
