"[The skull] appears to be weathered. It appears to have been there for a time," Sgt. Deeann Servey of the Davis County Sheriff's Office told KUTV.
Additional remains and pieces of clothing were found a short distance away and investigators used dental records to identify Greaves, according to Philly.com.
It took authorities several weeks to track down Greaves' relatives and share the tragic news. Investigators tried to reach family members through former classmates, but to no avail. On April 1, officials connected with the woman's cousin and uncle living in Florida, according to NJ.Com.
The circumstances surrounding her 1983 disappearance remain under investigation, however, Philly.com reported she was living with a friend in Voorhees before she relocated to a mobile-home park in Woods Cross, Utah.
Reports indicate a convicted murderer, Douglas Lovell, was once questioned abut Greaves' disappearance.
