The Los Angeles County Board of Supervisors has authorized a $100,000 reward for information leading to the arrest and conviction of the suspect alleged to have shot two Sheriff’s deputies in an ambush, Saturday evening.

The deputies, a 31-year-old woman and 24-year-old man, were attacked around 7 p.m. while sitting in their cruiser and were rushed to St. Francis Medical Center in Lynwood where they underwent surgery and are listed in critical condition.

The suspect is described as a male Black, age 28-30 years-old. Surveillance video shows the suspect approaching the patrol vehicle, parked at the Metro A (Blue) Line station at Willowbrook Avenue and Palmer Street, from behind and walking as if he was going to continue past it before turning, walking to the passenger side and firing into the cab, then running back the way he came.

“Two deputies were ambushed in a cowardly fashion,” Sheriff Alex Villanueva told reporters. “It pisses me off and it dismays me.”

The Sheriff’s department launched an overnight manhunt for the suspect, going door-to-door in some parts of Compton, while the FBI announced that it was offering resources to help with the investigation.

Anyone with information was encouraged to contact the Sheriff’s Department’s Homicide Bureau at 323-890-5500. Anonymous tips can be left for L.A. Crime Stoppers at 800-222-TIPS (8477), or at lacrimestoppers.org.

Local officials pleaded for calm Sunday after the shooting, which followed two weeks of protests against the Sheriff’s department over the fatal Aug. 31 shooting of 29-year-old Dijon Kizzee by deputies.

“I am devastated to learn of the tragedy that occurred in our city tonight,” Compton Mayor Aja Brown said Saturday, pledging the city’s cooperation to track down the shooter. “Both deputies and their families will remain in our prayers.”
