On February 3, 2024, 68-year-old Aristeo Zambrano was fatally shot at his business, Bay City Alternators, located at International Boulevard near 88th Avenue in Oakland, California. Zambrano, who immigrated from Michoacán, Mexico, in the 1970s, had a history of labor activism, having worked alongside Cesar Chavez in the United Farm Workers movement. He later established his auto repair shop, which he operated for over 30 years, becoming a respected figure in the community.
The tragic incident occurred shortly before noon, marking Oakland's tenth homicide of the year. Zambrano was pronounced dead at the scene. His family had long been concerned about his safety due to the area's rising crime rates. He is survived by three daughters and six grandchildren.
In March 2024, the Alameda County District Attorney's Office charged 33-year-old Robert Leigh Moore with Zambrano's murder. Authorities have not disclosed the motive behind the shooting. As of May 2024, Moore remained at large, with law enforcement agencies actively seeking information regarding his whereabouts.
Zambrano's death prompted community outcry over escalating violence in Oakland. Residents organized rallies demanding action to address the city's crime wave and to honor Zambrano's legacy as a community leader and advocate for workers' rights.
