Circumstances of Disappearance


Donna Lass was last seen in South Lake Tahoe, she left her residence without her vehicle or personal belongings. Lass worked as a nurse at the "Sahara Hotel-Casino". Her last entry in the nurse's log book was at 1:50 a.m., and although her car was found parked at her apartment complex in nearby Stateline, she wasn't seen after leaving the Sahara.
The next day, an unknown male called her landlord and employer, stating Lass wouldn't be returning due to a family emergency. The call was a hoax, and there has been no trace of Lass ever since.
Donna Lass may be the "last" suspected victim of the Zodiac Killer, though her body has never been found. A Zodiac letter gave clues to her body, but it has never been found. A few artifacts belonging to Lass were found in what appeared to be a shallow grave, but no body surfaced.
