Santa Clara County sheriff’s detectives have identified and arrested a man in a shooting at a Valley Transportation Authority facility in San Jose that left one person dead Friday. The department said 33-year-old Duc Minh Bui was the sole shooter and is “responsible for the victim’s death.” Bui is an employee at VTA and supposedly worked with the victim. The shooting was initially reported just before 10 p.m. Friday at VTA’s Chaboya Division Yard in the 2200 block of South Seventh Street. Officers responded to the scene to find a man suffering from “at least one gunshot wound.” The victim was pronounced dead at the scene after the San Jose Fire Department and county EMS arrived. Sheriff’s officials identified the victim as a VTA employee but did not release the victim’s identity Sunday. Due to the incident, VTA increased its security at all facilities. “VTA is committed to supporting its employees during this difficult time, and mental health professionals have been made available to employees and their families,” the agency said in a news release Saturday. Raj Singh, president of the Amalgamated Transit Union Local 265, said employees are still in shock. He added that amid the “confusion and chaos,” the person who died was a beloved individual at VTA. “I had the pleasure of working with him for the last seven or eight years since he was at this division; we lost a good person. He’s a very good individual,” Singh told NBC Bay Area on Saturday. This is the second deadly shooting in three years that has impacted the VTA community. In 2021, an employee shot and killed nine coworkers before taking his own life. “This incident is triggering some of our folks. We really thought we were past some of the stuff from before, and obviously, this is going to spur a lot of that back,” Singh said. Following the incident, employees gathered to set up a memorial to remember their colleagues and bring flowers, candles and balloons.
