The man suspected of fatally shooting Pomona Police Officer Shaun Diamond on Tuesday while the SWAT officer was serving a search warrant was charged today with capital murder, the Los Angeles County District Attorney’s Office announced. 

David Martinez (dob 3/02/78) is scheduled to be arraigned today at the Foltz Criminal Justice Center, Department 30, in case BA431000. Prosecutors will ask that he be held without bail. 

Deputy District Attorneys Jack Garden and Andrew Kim in the Crimes Against Peace Officers Unit are assigned to the case. 

Diamond, a 15-year law enforcement veteran, was shot in the pre-dawn hours Wednesday in San Gabriel while taking part in a multi-agency operation targeting the Mongols motorcycle gang. He died the following day. 

Martinez, a suspected Mongols motorcycle gang member, was charged with one count of murder with the special circumstance of murder of a police officer engaged in his duties. The complaint also includes gun and gang allegations. Prosecutors will decide later whether to seek the death penalty. 

The case remains under investigation by the Los Angeles County Sheriff’s Department.
