Los Angeles County Sheriff’s Sergeant Alfonso Lopez, 47, died October 24th after an apparent medical emergency while driving his patrol vehicle in Compton.

Around 5:30 a.m., authorities rushed the sergeant to St. Francis Medical Center after a citizen reported seeing the deputy slumped over and unresponsive in his patrol car, which was crashed into a fence.

The sergeant had left the station to provide help in a stolen vehicle chase, but the pursuit had been canceled just as Lopez was driving out of the parking lot. His vehicle was found 1 block away.

Authorities said an autopsy would be conducted to determine Lopez’s cause of death.

Lopez, a 27 year veteran, is survived by his wife and 2 adult children. He spent many years with the department in the special victims unit on child sexual assault cases and had been transferred to the Compton station a year ago.
