Of course, we have no idea how much distance the skull has moved in the 16 years since Donna Lass was dumped in this area in 1970 (assuming it was shortly after she was murdered). The skull could have been disturbed by animal predation or water flow, but let us assume it was found in the approximate position it was placed by her killer. A drainage ditch would a viable method of concealment preferable to digging a fresh grave, although one must stress, not necessarily where her body was initially placed.
DONNA ANN LASS (25) One could argue that the murderer of Donna Lass knew well this location by Fuller Lake, and opted to dispose of her body in this region because he felt confident he was not going to be disturbed by the unknown. Maybe he was a PG&E worker, who understood the advantage of using a drainage ditch for concealment and the eradication of evidence. Another thing to consider, is that the least effort principle would be blown out of the park if the killer had lived in close proximity to Donna Lass. He would be obligating himself to a 152 mile round trip, with the greatest risk on the outbound journey. What is the possibility that the murderer of Donna Lase chose a deposition site he was familiar with, on his way home? Were there any "persons of interest" in the Donna Lass case who were residents of Placer County to the west of Lake Spaulding?
Two skulls and a jawbone were found in the area surrounding Lake Spaulding, so it's not out of the question that the murderer of Donna Lass had killed on more than one occasion. However, it must be remembered that the areas around Lake Tahoe are a popular dumping ground for nefarious individuals wishing to evade justice.
