Salvador Alcala Lopez, 24, was shot and killed in San Bernardino, California, on June 18, 2016. He was found dead at the scene from gunshot wounds. Investigators have said the circumstances suggested the shooting may have been connected to gang activity, but the case has been hindered by a lack of witnesses willing to come forward.

The murder occurred during a period when San Bernardino County was experiencing a rise in violent crime between 2015 and 2016, a backdrop that police say complicated efforts to solve cases. Despite public appeals and efforts by the San Bernardino Police Department, no arrests have been announced and the case remains unsolved.

If anyone has information about Salvador’s death or saw anything on June 18, 2016, please contact the San Bernardino Police Department or submit an anonymous tip.
