On February 4, 1979, 24-year-old Michael Olson was one of three employees executed during a robbery at a Payless Drug Store in San Mateo, California. Olson and coworkers Tracy Anderson and Billy Baumgartner were shot in the back of the head during the attack, which left the community stunned and the case unsolved.

The victims’ families have actively appealed for public assistance and participated in press conferences, and rewards have been offered for information leading to an arrest and conviction.

The crime remains unsolved. If anyone worked at or near that Payless Drug Store in 1979, or remembers unusual activity or people in the area around February 4, 1979, please contact the San Mateo Police Department with any information.
