Roman Valenciano was headed to pick up his mom from work Thursday when his gray Nissan Sentra crossed paths with a silver Ford Mustang on San Mateo Boulevard just after 1:45 p.m. Surveillance footage shows the Mustang making an abrupt U‑turn and cutting directly in front of Valenciano’s car in heavy traffic. Moments later the Mustang brake‑checked the Nissan, stopping in the lane and forcing the younger driver to slow down. Detectives say the Mustang’s driver then pulled even with Valenciano and fired at least two shots into his sedan, one hitting him in the driver’s seat. The gunfire matched a ShotSpotter alert recorded in the area at that time.
Police arrived within minutes and attempted emergency aid, but Valenciano did not survive. Witnesses described the scene as chaotic, with people on foot trying to help and bystanders in tears as officers worked at the traffic stop where the Sentra came to rest.
Investigators tracked the suspect vehicle as it circled back to the area multiple times and later tried to hide evidence. Police say the Mustang was taken to a body shop and repainted black in an apparent bid to shield its identity. Automated license‑plate readers ultimately led detectives to the car and to Cecilio Lopez, who was on probation for a prior felony. Cell‑phone data also placed him at the scene around the time of the shooting.
Lopez was arrested Friday evening at a North Valley residence. He now faces charges including open count of murder, tampering with evidence, shooting at or from a vehicle resulting in death, and being a felon in possession of a firearm. Court proceedings are expected to begin as the case moves forward.
Family members and friends of Valenciano described him as a young man who was close with his mom and had a bright future ahead. They spoke of the senselessness of the violence, saying he was simply doing a favor for his mother when the encounter turned deadly.
Police officials are urging anyone with additional information or video of the incident to come forward. They noted that crimes like this not only take lives but deeply impact communities trying to feel safe on their city streets.
