Found Deceased CA - Donna Lass, 25, South Lake Tahoe, 6 Sept 1970

I believe this is the JD thread, skull found in Placer Co. August 1986 near I-80 and Hwy 20.

Thank you so much for finding that, @Caring1 .
 
*Cross posting:

While the investigation went nowhere at the time, the Placer County Sheriff's Office did find a skull off Highway 20 near Interstate 80 more than a decade later. However, detectives at the time couldn't identify that person.

The skull was preserved and, in recent years, was re-examined by Placer County's new cold case team.

With advancements in DNA technology at their disposal, the skull found in 1986 had DNA that matched with a member of Lass' family. The remains were then positively identified as that of Donna Lass
 
states "skull was discovered in a drainage ditch near
Interstate 80 and State Highway 20."


That would seem to be somewhere in this area:
Google Maps
If you drove from South Lake Tahoe where Donna
Lass disappeared, assuming for instance that you
drove via roads following the west shore of Lake
Tahoe, that's about 110km of road to travel on.
 
Donna Ann Lass

Missing since September 6, 1970 from South Lake Tahoe, El Dorado County, California.

Classification: Endangered Missing

Vital Statistics

Date Of Birth: November 3, 1944

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.

I wonder if that 'shallow grave' containing her artifacts was anywhere near where the skull was found?
 
Donna and Judith, both nurses and located in Placer county. And Judith's murder has often been related to Nancy Bennallack's murder... which is solved: Richard John Davis was identified as the murderer; so is there any connection between Davis and Donna?
 
The 25-year-old Lass was reportedly last seen Sept. 6, 1970, "walking with a young, blonde man near the apartment she had rented the day before and never lived in," according to a newspaper article published the year after Lass went missing. Hiring a private investigator and offering a $500 reward for information, Lass' family kept the search alive despite SLT police following "every lead to a dead end."

A postcard depicting a Sierra scene sent to authorities and a Christmas card mailed to Lass' sister raised suspicions Lass could be a victim of serial murderer the Zodiac Killer. The postcard included what appeared to be clues, leading investigators to search unsuccessfully for Lass in Tahoma and Zephyr Cove.
 

Donna Ann Lass, age 25
Went missing 6 September 1970.
Identified in December 2023.

It is good that this 53 year old missing person case has been partially solved by the recent identification of some previously unknown remains. It is now an unsolved homicide case. Perhaps new interest and potentially connected evidence will lead to the identification of her killer.

Anyone with information was asked to contact South Lake Tahoe police detectives at crimetips@cityofslt.us and refer to case 0070-6436.
