Vital Statistics at Time of Disappearance
Details of Disappearance
Donna was last seen in South Lake Tahoe, she left her residence without her vehicle or personal belongings. On September 6, 1970, Lass was working inside the old Sahara Hotel-Casino, which today is the Horizon. She signed the work log at 1:50 a.m. When she left she was never seen nor heard from again.
Donna had lived in San Francisco and had worked at Letterman Hospital there prior to moving to Lake Tahoe. She vanished three months later.
Six months after her disappearance – the San Franscio Chronicle received a postcard that may have been sent by the Zodiak killer. Investigators said the postcard suggested Lass was his 12th victim and that she was buried somewhere in the Sierra. That possibility hasn't been entirely discounted as the Lass cold case remained unsolved.
