The skull was handed over to the county coroner's office to be preserved until further advancements in forensics could possibly help identify the remains.
The sheriff’s office said it recently created a cold case team with the Placer County District Attorney’s office, dedicating additional resources to help bring unsolved missing persons and suspicious death cases to a close.
The new team sent the skull to the California Department of Justice with hopes that advancements in DNA technology could help identify its source.
According to the sheriff’s office, the California Department of Justice Bureau of Forensic Services matched DNA taken from the skull with the DNA of a member of Lass’s family, which was obtained by the South Lake Tahoe Police Department during the missing person’s case investigation.
The match allowed investigators to identify the skull as the remains of Lass.
Last week, the South Lake Tahoe Police Department notified Lass’s family that she had been found.
"We are extremely grateful that this team effort was able to bring closure to the Lass family and are hopeful that cold case detectives can continue to make advances in these cases," the sheriff’s office said in a press release.
Although Lass has been found, the case remains open as investigators vow to investigate future leads on the matter. It is still unclear how Lass died.
