Guillermo Mendoza-Rojas, 21, was shot and killed on September 26, 2009, in Canoga Park, Los Angeles. The shooting occurred around 3:06 a.m. in the 20900 block of Gresham Street; Guillermo was struck twice. His cousin, 28-year-old Isidro Meza-Rojas, was also fatally shot in the same incident.

The LAPD investigated, noting there were no immediate witnesses and that the case had complications investigators attributed to the area’s pattern of gang-related violence. Later federal indictments against members and associates of the Orange County Mexican Mafia describe the organization’s control over local Latino gangs and list murder and attempted murder among the charged offenses; those filings reference the broader pattern of violence that included this killing.

Who knew Guillermo or Isidro, or has information about the events on Gresham Street that night?
