On December 2, 1993, 65-year-old Richard Bateman was one of three people fatally shot inside the California Employment Development Department office in Oxnard, California. Bateman was visiting on behalf of a nonprofit that helped disabled adults find employment when a gunman opened fire inside the office, killing him and two employees, Phillip Villegas, 43, and Anna Velasco, 42.

The shooter, identified as Alan Douglas Winterbourne of Ventura, fled in a car after the Oxnard attack. During a high-speed pursuit toward another unemployment office in Ventura, he shot and killed Oxnard police officer James E. O Brien. The chase ended outside the Ventura office, where Winterbourne was killed by police as he emerged from his car with a rifle in hand.

Authorities reviewed documents Winterbourne left behind but found no definitive motive. If anyone knew Richard Bateman or has information about his visit to the Oxnard office that day, please share what is known.
