Alex Giovani Zepeda was 19 and a college sophomore when he was shot dead outside a Halloween party in Wilmington, Los Angeles, on October 28, 2017. He stepped outside the party at about 1:45 a.m. to hang out with other attendees; a person approached and opened fire. Zepeda was struck multiple times and pronounced dead at the scene at 2:05 a.m. The Los Angeles County coroner listed the cause of death as homicide by gunshot wounds.

Investigators concluded the shooting was a targeted attack tied to a long‑running rivalry between Eastside and Westside Wilmas; detectives said the party had been attended by members of both groups. A 14‑year‑old boy was arrested on November 2, 2017, in Wilmington and charged with murder; his name has been withheld because of his age and he was held in juvenile detention in Downey. Zepeda was a criminal justice major at California State University, Fullerton and had interned for Los Angeles City Councilman Joe Buscaino, who publicly expressed sorrow over the killing.

If anyone who knew Alex or who attended that Halloween party can help fill gaps about what happened that night, please come forward with information.
