SOUTH WHITTIER – The FBI on Wednesday added a 37-year-old gang member sought since the 2000 shooting of a deputy in South Whittier to its “Ten Most Wanted” list, authorities announced. The agency offered a $100,000 reward for the capture of Emigdio Preciado Jr., who authorities say sprayed a patrol car with 21 rounds from an assault rifle when deputies tried to stop a van in unincorporated South Whittier on Sept. 5, 2000. The shooting, which occurred at about 3:15 a.m., triggered a massive hunt for the van’s occupants. In the search, authorities closed two nearby elementary schools and detained some students and several guests at a motel. Deputy Michael Schaap, then a nine-year veteran of the Sheriff’s Department, was shot in the head. Taken to St. Francis Medical Center in Lynwood in critical condition, Schaap eventually recovered and returned to work, according to sheriff’s officials. Although Preciado remains at large, authorities arrested three accomplices shortly after the shooting. Omar Jimenez, 30, pleaded no contest to assault and was sentenced in 2003 to 15 years in state prison. Jose Guardado, 42, and Carlos Gutierrez, 30, were each sentenced in 2003 to 19 years in state prison for assault with a semiautomatic weapon on a peace officer. On Tuesday, the Los Angeles County Board of Supervisors authorized a $50,000 reward for information leading to Preciado’s arrest and conviction. A spokesman for Whittier-area Supervisor Don Knabe said the reward was boosted from an original $10,000 in hopes that it would prompt witnesses to come forward. Any information about this case should be directed to any local law enforcement agency, or the Los Angeles County Sheriff’s Department’s Homicide Bureau at (323) 890-5500. – From staff and wire reports 165Let’s talk business.Catch up on the business news closest to you with our daily newsletter.

Immediately after the shooting, Timberlake was overheard by a witness pleading with Schaap: “Talk to me! Don’t die on me!” Sheriff’s officials said the deputies never got the chance to step outside their vehicle before it was sprayed with bullets. Preciado, a member of the Southside Whittier street gang, is the 485th person named on the list since it was started in 1950. FBI officials believe Preciado is in Mexico.
