Sophia Darlene Vasquez Rubin, 31, was fatally shot on February 1, 2017, in San Bernardino, California. The shooting occurred about 11:30 a.m. while she sat in a parked car on the 3500 block of Mountain View Avenue. Rubin was found bleeding in the street and taken to Dignity Health–St. Bernardine Medical Center, where she was pronounced dead.

Police and witnesses identified the suspect as 39-year-old Christian Omar Jaciento, described as Rubin’s former boyfriend; their recent breakup is believed to have been a motive. Jaciento fled the scene in a white four-door car; the vehicle was later recovered at an apartment complex in Riverside but he was not located. Authorities deployed a SWAT team to the apartment, described the killing as an execution, and issued a warrant calling him armed and dangerous.

Rubin was a mother of two and her death shocked the community. Police asked the public for help in locating Jaciento and continued the investigation. If anyone knew Rubin, Jaciento, or saw the white four-door car in February 2017, please come forward with information.
