Steven Bell, 24, died of a gunshot wound to the head, Los Angeles County Coroner's Lt. Larry Dietz told Patch in a telephone interview.
According to a witness, the victim and his friend had just left a family gathering on East 148th State and South Loness about 9 p.m. Sept. 21, when someone shot into their vehicle, striking the victim seated in the front passenger seat.
The driver of the vehicle was not hit by the gunfire and ran off before deputies arrived.
Bell died at a hospital, authorities said, the first of three men to die within a four-hour period between Sept. 21 and Sept. 22.
Compton police have released no suspect information.
