Olga Harper, 75, a white woman who lived alone in Los Angeles, was last seen entering her apartment on April 20, 1975 and was found dead there on April 23. The victim had been beaten, raped, and murdered. Her death was described as part of a pattern of violent crimes that targeted elderly women in Los Angeles during the 1970s.

Investigators later grouped her killing with a series attributed to a suspect known as the Westside Rapist, who was later identified as John Floyd Thomas Jr. Although Thomas was not formally charged in Harper’s murder, law enforcement included her name among suspected victims because of similarities in circumstances and modus operandi with other attacks on elderly white women living alone.

The case remains officially unsolved. Does anyone have information about Olga Harper, her neighborhood in April 1975, or contacts who might have known her routines?
