Ashly Yhuky Tianson was 19 and from Daly City when he was fatally shot on May 14, 2021, in San Mateo. The shooting happened around 9 p.m. while he sat in the driver’s seat of his car in the San Mateo Adult School parking lot, picking up his girlfriend after work. Three individuals approached the vehicle in an attempted carjacking; Tianson used his body to shield his girlfriend and suffered a gunshot wound to the abdomen. He was taken to a local trauma center and later died of his injuries.

San Mateo police investigated immediately; witnesses saw a group flee the scene. Two 16-year-old suspects were arrested, one in San Jose and one in San Mateo, and booked into Hillcrest Juvenile Hall on charges including murder and attempted murder. Authorities described the incident as isolated and not connected to activities at the nearby schools. Tianson’s family recalled his plans to join the Army, his recent high school graduation, and his role supporting the family; they set up a GoFundMe to help with funeral costs.
