Sylvia Vogel, a 71-year-old white woman from Los Angeles County, California, was found dead in her residence on March 22, 1975. At the time her death was unexplained; she was buried at Mount Sinai Memorial Park in Hollywood Hills, Los Angeles.

Forensic evidence later linked Vogel’s death to John Floyd Thomas Jr., a serial offender active in Southern California in the 1970s and 1980s whose victims were often older white women living alone. Thomas was arrested in 2009 after DNA tied him to multiple unsolved murders and was charged in several killings. No other suspects were arrested in connection with Vogel’s death.

Does anyone have memories of Sylvia Vogel, her neighborhood, or details from 1975 that might help illustrate her life or the circumstances around that case?
