Maureen Louise Sterling was 12 when she disappeared from Santa Rosa, California, on February 4, 1972. She and 13-year-old friend Yvonne Lisa Weber had been at the Redwood Empire Ice Arena that evening and were last seen hitchhiking on Guerneville Road northwest of the city.

Their remains were found December 28, 1972, down a steep embankment about 66 feet off the east side of Franz Valley Road. Decomposition left the cause of death undetermined. Maureen and Yvonne are counted among at least seven female hitchhiker victims linked to the Santa Rosa hitchhiker murders of 1972–1973.

Investigators followed multiple leads, including reports the girls had been approached that night by a tall, slender man who offered them marijuana; one witness later said the man resembled Ted Bundy, but no definitive connection was established. No arrests have been made and the killer remains unidentified.

If anyone knew Maureen, Yvonne, or saw them that night, please share information that could help finally close this case.
