Arthur Samuel Romero, 51, of Covina, California, was shot and killed on October 21, 2017, in the 18800 block of Elizondo Street in the South San Jose Hills area of the San Gabriel Valley. The shooting occurred about 7:49 p.m. during what appeared to be a social gathering at a private residence. Romero was found on the sidewalk outside the house; another victim, Roberto Diaz, 32, was found in the driveway. Both men were pronounced dead at the scene.

Deputies arriving at the scene reported the party’s attendees had fled, and the homeowners heard but did not witness the shooting. Los Angeles County Sheriff’s investigators described the scene as chaotic and said there were few concrete leads. No arrests have been announced and the Homicide Bureau has asked anyone with information to contact them or Crime Stoppers.

Does anyone who was in the area that night or who knew Arthur Romero or Roberto Diaz have information that could help the investigation?
