The remains of the Green River killer have been identified as 15-year-old Lori Anne Radzbotnick, who ran away.

The Green River Killer’s victim has been identified nearly four decades after her body was found.

In 1985, two sets of human remains were found on a steep bank in Auburn, Washington. News release from the King County Sheriff’s Office. At the time, the remains were being investigated by the Green River Task Force—set up in the early 1980s to investigate a series of bodies found in the woods along the Green River in Washington state. The boxes have been identified as Bones 16 and Bones 17, the sheriff’s office said.

In 2002, the Green River Killer, Gary Ridgway said he led officers to the location and placed the victims there. He pleaded guilty in 2003 to the murders of those two victims and 46 other women and girls. In 2012, the remains, known as Bones 16, were identified by DNA testing as Sandra Majors.

The sheriff’s office said as of this week, investigators had not been able to determine whether the 17 bones were those of 15-year-old Lori Anne Radzbotnick, who ran away from home in 1982. Radzbotnik lived in Lewis County, about 75 miles from Auburn.

The investigators used a forensic genomics test in collaboration with Parabon NanoLabs. The lab was able to create a new DNA profile. Rasbotnik’s mother provided detectives with a saliva sample, and the University of North Texas conducted a DNA comparison test that “confirmed they were Lori Anne’s remains,” the sheriff’s office said.

Ridgway’s first killers were discovered in 1982 and Ridgway was arrested in 2001. In 2003, Ridgway agreed to plead guilty to all murders in King County to avoid the death penalty. According to Kings County, Ridgway admitted to 48 counts of aggravated first-degree murder. He is in prison for the rest of his life Washington State Penitentiary in Walla Walla without possibility of release.

Two victims not identified: Although Ridgway confessed to their murders, King County said he was unable to provide any significant information that could help identify them. Page dedicated to the investigation Inside the Green River Killer.

The county also said there were three women, Cassie Ann Lee, Kelly Kay McGinnis and Patricia Ann Osborne, who were last seen in the Seattle area in the early 1980s. They are still missing today and “listed on the Official Green River Murders List,” but Ridgway has not been charged in their disappearance.

The county noted that authorities are searching for three women who have been missing since the early 1980s, one of whom remains unidentified. One of the women was an associate of Ridgway’s other victim, Tammy Lyles. Police are asking anyone with information about these women or any other crimes related to the Green River case to contact them.
