Guillermo Ceja, a 20-year-old resident of Pomona, California, tragically lost his life on June 24, 2018. The incident occurred near Fanshaw Avenue and Vamana Street in Pomona. According to reports, Ceja was in a car with friends when they encountered another vehicle, leading to a confrontation. Witnesses stated that Ceja exited his vehicle and approached the other car, at which point someone inside the other vehicle opened fire. Ceja was struck by a bullet but managed to return to his car.
The suspect's vehicle fled the scene, and Ceja's friends attempted to drive him to safety. However, they abandoned him on the road at Aliso Street and Westwood Place, approximately two miles from the shooting site and half a mile from Pomona Valley Hospital. Despite efforts by police and paramedics to revive him, Ceja was pronounced dead at the hospital, with the cause of death being a gunshot wound to the chest.
The investigation into Ceja's death quickly led to the identification and arrest of Cristobal Limon-Aguilar, a 22-year-old Pomona resident. The following morning, investigators spotted Limon-Aguilar's vehicle and conducted a traffic stop, leading to his arrest on suspicion of murder. Witnesses and surveillance footage played a crucial role in linking Limon-Aguilar to the crime. During a search of his residence, authorities discovered guns and ammunition, although it was unclear if these were used in the shooting. The Los Angeles County District Attorney's Office charged Limon-Aguilar with murder on June 27, 2018, and he was held without bail. He faced the possibility of life imprisonment if convicted.
The motive behind the shooting remained unclear, with investigators unable to determine what sparked the confrontation between the two vehicles. The case garnered significant attention, and an online fundraiser was established to support Ceja's family. Described as a hardworking and generous individual, Ceja was remembered for his dedication to his family and his kind-hearted nature. The Pomona Police Department continued to seek information from the public to aid in their investigation, urging anyone with details to come forward.
