Raymond August was 28 and an Oakland resident when he was killed on July 27, 1989. His death was one of several linked to a series of random shootings near Interstate 580 that terrorized the Oakland area in 1989, in which victims were shot on or near the highway while in or near their cars.

Authorities later identified Charles Arnett Stevens as the person responsible for the string of attacks that also claimed the lives of Leslie Ann Noyer, Lori Anne Rochon, Laquann Sloan and others. Stevens was charged with multiple counts of first-degree murder and attempted murder; legal proceedings in the broader case were extensive.
