Rhonda Faye Lyons, 26, was one of three people killed when a gunman opened fire at an end-of-summer party at the Mother Lode Bar in Sacramento on October 1, 1982. The attacker, identified in reports as Douglas Mozingo, fired an automatic rifle and a pistol into the crowd; nine others were wounded. Rhonda died later at a hospital; two other victims, Pamela McCoy and Randall Sherwood, were killed at the scene.

Mozingo was taken into custody at Sacramento Medical Center after a suicide attempt and was charged with three counts of murder and nine counts of attempted murder. The shooting devastated families and the local community and prompted public discussion about gun violence and safety.
