DONNA LASS: THE MISSING BLUE SUIT

1/31/2026

 
Picture
Thanks to the recently unveiled FBI files regarding the disappearance of Donna Lass (25), last seen at the Sahara Tahoe Hotel & Casino on September 6th 1970 at 2:00 am, it is safe to say that Donna Lass was not abducted from the casino (or its parking lot) at the end of her shift, and didn't meet foul play by the hands of a random stranger, who intercepted her journey while she returned back to her apartment in the early morning hours (whether she was walking or in a vehicle).

Donna Lass had changed out of her nurse's uniform and into a navy blue slack suit shortly before her shift end at 2 am. These were the clothes the young woman was last seen wearing at the Sahara Tahoe Hotel & Casino, that were not found in her apartment by investigators, which may lead some to believe she never arrived home that morning. However, her purse (handbag for carrying personal items) was discovered in her apartment, containing money, her personal cosmetics and car keys, which almost certainly suggests she returned back to her home after leaving the casino. She may have walked home, or accepted a lift from somebody at the casino (or during her journey), but the important thing to remember here, is that her navy blue slack suit was missing, yet her purse wasn't.

Her 1968 Chevrolet Camaro was found outside her Monte Verdi apartments on 3893 Pioneer Trail Road by the South Lake Tahoe Police Department on September 13th 1970, which suggests, that had she met foul play that morning, we are still unable to rule out that she drove to work on September 5th 1970, and returned home in her car on September 6th 1970, knowing now her car keys were found in her purse inside the apartment. In absence of any confirmed sightings of Donna Lass after 2 am on September 6th 1970, the fact that her navy blue slack suit was never seen again, strongly indicates she didn't change out of these clothes after arriving home that morning. Especially when we consider a malicious phone call was received by the Sahara Tahoe Hotel & Casino on September 7th 1970, claiming falsely that Donna Lass had been called out of town for a family illness and would not be returning to work for a few days. This obviously means that Donna Lass met foul play between the time she returned to her apartment on September 6th 1970, to the time the malevolent call was made to the casino the following day (September 7th 1970). And it tells us that she never likely removed her navy blue slack suit and went to bed.

EXCERPTS FROM THE FBI FILES OBTAINED BY TRAVIS MILLER
Picture
The private investigator's report stated that the mysterious caller identified himself as Mr. Davis (Donna's new landlord), which Nick Davis vehemently denied was him. It would have been extremely stupid to have murdered Donna Lass and then used your own name to excuse her absence due to family illness, that obviously would have been discovered in due course by investigators. If this was the case, the caller wasn't Nick Davis. But this detail about "Mr. Davis" was not mentioned in the FBI files, which only referred to the phone caller as an unknown male. Even if the caller mentioned no name, it is clear that this person was involved in the disappearance (and likely murder) of Donna Lass, who knew where she worked, and felt the need to buy time and phone the casino to excuse her absence.

A random killer (unknown to Donna Lass and living distant from her residence), who murdered her at the apartment or abducted her from it, has absolutely no need to make contact with the Sahara Tahoe Hotel & Casino and make a bunch of excuses. The only person who needs to buy time is somebody the police would have chosen to visit first, such as friends, neighbors  and work colleagues. Somebody who may have given Donna Lass a lift in the early hours of September 6th 1970, somebody who rode in her vehicle that morning, or somebody that visited her apartment after she arrived home from work. Somebody that killed or abducted her while she was still wearing her navy blue slack suit, who needed to confuse the timeline of her disappearance and murder. The clothes she left work in vanished alongside her, but her purse, that she almost certainly carried with her when she arrived at work on September 5th 1970, found its way back to her apartment on September 6th 1970.

​It appears as though Donna Lass met her demise shortly after leaving work and arriving home. Was it a co-worker or a resident at the Monte Verdi apartment complex at ​3893 Pioneer Trail Road? The final question is why did the "killer" make the phone call on September 7th 1970 and inform the casino that Donna had gone out of town, rather than phoning her workplace in the daytime hours of September 6th 1970. Was he aware that Donna Lass wasn't working on the evening of September 6th 1970, and had the day off? There can't be many other reasons why the perpetrator waited over 24 hours to phone the casino. If this was the reason, it may narrow the focus to somebody who was not only familiar with her profession, but to somebody who knew her work schedule, such as a friend or close work colleague. A person who didn't want this crime investigated as a murder and needed to make the body disappear.
