Nazario Ramirez, age 54, a Latino man from Lancaster, California, was found shot to death on August 17, 2025, in the remote Lake Los Angeles area east of the city. Deputies from the Lancaster Sheriff's Station responded around 4:48–4:50 p.m. to reports of gunfire near 215th Street East and East Avenue Q/East Palmdale Boulevard, where they discovered three victims—two men and one woman—inside two vehicles on the desert roadside. Paramedics pronounced all three dead at the scene.
The county medical examiner later identified the deceased as Nazario Ramirez, age 54; Juan Arteaga Díaz, age 44; and Beverly Cassese, age 65.
Investigators pieced together a harrowing sequence. While driving east, the shooter allegedly pulled alongside a vehicle occupied by Juan Arteaga Díaz and Nazario Ramirez, age 54, and opened fire multiple times. He then drove up to a second vehicle in the same stretch of desert and shot Beverly Cassese, age 65. Authorities described the attack as brazen and unprovoked, carried out on a desolate corridor where the only witnesses were the wind and the sand.
By the following days, the Los Angeles County Sheriff's Department identified a person of interest and asked for public help locating him, describing a man believed to be traveling in a silver Nissan Altima. Soon after, homicide detectives announced they had detained and then arrested 32-year-old Axel Treviño in connection with the killings of Juan Arteaga Díaz, Nazario Ramirez, age 54, and Beverly Cassese. Authorities did not immediately disclose a motive.
The medical examiner ruled the manner of death for Nazario Ramirez, age 54, as homicide caused by multiple gunshot wounds, a finding that underscored the suddenness and violence of the ambush in the high desert. In the weeks that followed, news outlets reiterated that investigators believed the assailant struck from a moving car, aligning with the scene's sparse evidence and the tight timeline between the initial burst of shots and the discovery of the victims.
