Details of Disappearance

Lass disappeared from her job in South Lake Tahoe, California on September 6, 1970. She worked as a registered nurse at the first aid station at the Sahara Hotel-Casino and her last logbook entry was timed at 1:50 a.m. Her car was found parked near her apartment in Stateline, Nevada, but nobody saw her leave the casino.

In 1986, Lass's skull was found off Highway 20 near Interstate 80 in Placer County, California. No other remains or evidence was located at the time. The skull was identified as Lass's in December 2023, almost forty years after it was located, and over fifty years after Lass's disappearance. Her death is under investigation.
