On August 30, 1979, 21-year-old Frank Cash was shot and killed during a robbery at an auto parts store in East St. Louis, Illinois. According to reports, Cash pleaded for his life during the attack but did not survive his wounds.

The killings have been linked to Girvies L. Davis and Richard Ricky Holman, who were implicated in a series of violent crimes across Illinois in 1978 and 1979 and nicknamed the .22 Caliber Killers because of the firearms used in several murders. Both men were convicted in multiple slayings, including the death of Frank Cash; Davis received a death sentence and Holman, who was under 18 at the time of the crimes, was given life without parole.

Anyone who remembers the auto parts store, the area around East St. Louis in 1979, or has information about Frank Cash is asked to come forward.
