ANCHORAGE, Alaska — A woman known for 37 years only as Horseshoe Harriet, one of dozen or so victims of a notorious Alaska serial killer, has been identified through genetic genealogy and a DNA match, authorities said Friday.

The victim was identified Friday as Robin Pelkey, who was 19 and living on the streets of Anchorage when she was killed by Robert Hansen in the early 1980s, the Alaska Bureau of Investigation’s Cold Case Investigation Unit said Friday.

“I would like to thank all of the troopers, investigators, and analysts that have diligently worked on this case over the last 37 years. Without their hard work and tenacity, the identity of Ms. Pelkey may have never been known,” Alaska Department of Public Safety Commissioner James Cockrell said in a statement.

Hansen, who owned a bakery, gained the nickname “Butcher Baker” for abducting and hunting down women — many of them sex workers — in the wilderness just north of Anchorage through the early 1980s, when the state’s largest city was booming because of construction of the trans-Alaska pipeline.

The 2013 movie “Frozen Ground,” starring Nicolas Cage and John Cusack, chronicled the troopers’ investigation and capture of Hansen.

Hansen was convicted in the deaths of four women but confessed to killing several more, troopers said. At one point, he flew with investigators over an area north of Anchorage, where he pointed out where 17 of his victims were buried.

In 1984, Alaska State Troopers returned to those areas, where the remains of eight women were discovered. In total, 12 bodies have been found, and 11 of those have been identified, trooper spokesperson Austin McDaniel said.

The only person not yet identified is known only as Eklutna Annie, who is believed to have been Hansen’s first victim, McDaniel said. Her body was found near Eklutna Lake just north of Anchorage.

Genetic genealogy efforts are underway in hopes of also identifying her, Randy McPherron, an Alaska State Troopers cold case investigator, told The Associated Press.

“We really got our fingers crossed that we may know, find out who Eklutna Annie is,” he said, adding the timeframe could take up to a year.

Among the skeletal remains found in 1984, Pelsky was discovered lying on the ground near Horseshoe Lake, near the Little Susitna River just a few miles northwest of Anchorage, troopers said.

There was no ID on the body that became known as Horseshoe Harriet. Hansen told investigators she was a sex worker he abducted from downtown Anchorage sometime in the winter of 1983. He told investigators he flew her to the lake in his small airplane, murdered her and discarded the body. He didn’t know her name or much else about her.

The case was reopened in 2014, the same year Hansen died in prison at the age of 75.

The body was exhumed, and samples were sent to create a DNA profile, which was added to the FBI’s national missing person database. It didn’t provide an identification.

In September 2020, investigators made another attempt to identify the remains using genetic genealogy.

A bone sample was sent to a private lab and additional DNA was extracted and sent for Whole Genome Sequencing, troopers said. This data was then sent to another lab, where a DNA profile was generated and uploaded into a public access genealogy database in April.

Troopers said several close matches were found and used to create a family tree for the victim.
