Aryanna Avila, 23, a Hispanic woman, was shot during a car-to-car attack in the San Gabriel Valley and died after being taken to hospital on the morning of September 9, 2025. The shooting was reported about 1:34–1:35 a.m. near Arrow Highway and Irwindale Avenue; officers later found her in the passenger seat of a white sedan parked along Enid Avenue by Gladstone Middle School. The county medical examiner listed the manner of death as homicide, with a perforating gunshot wound of the neck.

Detectives from the Los Angeles County Sheriff’s Department Homicide Bureau and Irwindale Police canvassed the intersection where shots were fired and the nearby curb where the sedan stopped, collecting witness accounts and surveillance leads. Early reports say officers performed CPR roadside and that only the passenger was struck while the driver was uninjured. The Gun Violence Archive classified the incident as a drive-by, car-to-car shooting.

Investigators identified a suspect, Basilio Perez Valencia of Azusa; Irwindale and West Covina officers stopped his vehicle and took him into custody on September 10. Prosecutors filed charges on September 12, including murder and attempted murder counts with firearm enhancements, and court records show he was held without bail as the first Pomona Superior Court date approached. No definitive motive has been publicly established.

Did anyone in the area that night see the shooting, the suspect vehicle, or the white sedan after it pulled off the roadway?
