Steve Mauricio, 36, a Latino male, was found mortally wounded in the early-morning quiet of a Glendora neighborhood on Saturday, October 25, 2025. First responders were dispatched at about 2:20 a.m. to the 200 block of Forestdale Avenue, where a vehicle had come to rest after crashing into parked cars. Inside, they discovered Mauricio, who was pronounced dead at the scene.
The county medical examiner's records and subsequent local reporting identified him as a Fontana resident, with the place of death listed as a vehicle.
Detectives soon treated the case as a shooting. Community crime reporters noted the call for witnesses in the immediate aftermath, underscoring that investigators believed gunfire preceded the crash. Independent victim registries likewise recorded Mauricio as lost to gun violence that night in Glendora, echoing what officials were piecing together at the scene.
By Monday, authorities publicly released Mauricio's name and age, but they did not say what sparked the violence. The medical examiner's office had not yet finalized a cause and manner of death beyond the preliminary details associated with a vehicle scene, and the broader picture—how the confrontation unfolded, who pulled the trigger, and why—remained unsettled.
As of the latest reports, no arrests had been announced and no suspect description had been confirmed. Investigators asked anyone with information to contact the Los Angeles County Sheriff's Homicide Bureau or leave an anonymous tip with L.A. Regional Crime Stoppers, a plea that signaled just how early and fragile the case remained.
