Guillermo Ceja, 20, of Pomona, California, was shot and killed on June 24, 2018. The shooting happened near Fanshaw Avenue and Vamana Street after a confrontation between occupants of Ceja’s car and another vehicle. Witnesses said Ceja got out of his car and approached the other vehicle when someone inside opened fire. Ceja was struck in the chest, returned to his car, and friends tried to drive him to safety but abandoned him on the road at Aliso Street and Westwood Place, about two miles from the shooting scene and half a mile from Pomona Valley Hospital. He was pronounced dead at the hospital.

Investigators identified and arrested 22-year-old Pomona resident Cristobal Limon-Aguilar the following morning after spotting his vehicle and stopping it. Witness statements and surveillance footage were cited in linking him to the incident. Authorities recovered guns and ammunition at Limon-Aguilar’s residence, though it was not clear if those items were the weapon used. The Los Angeles County District Attorney charged Limon-Aguilar with murder on June 27, 2018; he was held without bail. The motive for the confrontation remains unknown.

Anyone with information about the shooting or what led to the confrontation is asked to come forward.
