Farmington • More than a year after a hiker discovered the skeletal remains of a 23-year-old Utah woman who disappeared decades ago, police are analyzing DNA and interviewing people who knew her.

Detectives say they have ruled out one suspect: Douglas Lovell, a death row inmate who was convicted of killing a woman in 1985 so she couldn't testify against him in a rape case in nearby Farmington.

Investigators are working their way through a list of remaining suspects in the death of Theresa Rose Greaves, the Standard-Examiner reported.

Detectives are also talking to people who knew Greaves, who was reported missing after leaving her Woods Cross home for a job interview in Salt Lake City in August 1983, said Davis County sheriff's Sgt. DeeAnn Servey.

She made it to Salt Lake City and called a friend but was never heard from again.

Lovell had been questioned before in her disappearance and was eliminated early on, though Servey declined to say exactly how he was ruled out.

A hiker found Greaves' skull in a heavily wooded area near a U.S. Highway 89 frontage road in February 2015. Officers searched the area and discovered the rest of the skeletal remains and clothing buried and covered with oak brush and leaves.

Police haven't been able to determine exactly how she died, but the evidence indicates her death wasn't an accident, Servey said.

Greaves moved from New Jersey to Utah after meeting a Mormon missionary and converting in the late 1970s.

The missionary was Kevin Higgs, who lives in Riverdale. He told the newspaper that he baptized Greaves into the church.

After her remains were found last year, the host of the genealogy-themed radio show "Extreme Genes" helped detectives find her remaining family. Scott Fisher used Facebook and a school administrator to find one of her high school classmates, who put him in touch with Greaves' relatives.

An anonymous donor paid to send her remains back to the family.
