Joseph Fierro, 59, was shot and killed on the evening of July 21, 2025, while driving east on the Pomona Freeway near the Garey Avenue off-ramp. California Highway Patrol units arrived about 8:30 p.m. and found him outside his vehicle with an upper-body/neck wound. He was taken to a nearby hospital and later pronounced dead. The Los Angeles County Medical Examiner identified Fierro and listed the cause of death as a gunshot wound to the neck, ruling the death a homicide.

Initial accounts say the shooting followed a confrontation on the freeway; officers provided life-saving measures at the scene. Traffic was halted under a SigAlert while investigators searched the off-ramp area. Authorities detained one person at the scene, and later reports said that individual was taken into custody and a firearm was recovered, though that person had not been charged at the time of reporting. CHP’s Major Crimes Unit is leading the investigation and anyone with information was asked to contact investigators.

Does anyone who travels that stretch of the Pomona Freeway regularly recall seeing or hearing anything unusual that night?
