DNA Evidence Breakthrough and Match

Advances in DNA technology allow investigators to re-examine evidence collected in 1987. Semen samples from multiple victims are conclusively matched to the DNA profile collected from Gary Ridgway.

1. The Washington State Crime Lab begins using a new DNA method (touch DNA/PCR) to test Green River killer evidence collected years earlier.
2. Ridgway's DNA is definitively matched to samples from victims Marcia Chapman, Opal Mills, and Cynthia Hinds.

Ridgway First Identified as a Suspect

Gary Ridgway is first contacted by police after the disappearance of Marie Malvar. Her boyfriend reports seeing her get into a pickup truck traced back to Ridgway. He is interviewed, denies involvement, and passes a polygraph test in May 1984.

1. Victim Marie Malvar disappears. Her boyfriend reports the truck she was seen getting into is Ridgway's, leading to police contact.
2. Ridgway is officially interviewed as a prime suspect and submits to a polygraph examination, which he passes, diverting suspicion for years.
3. Police search Ridgway's home and vehicles and take DNA/bodily samples, but there is still insufficient evidence for an arrest.

49th Conviction (Rebecca Marrero)

Ridgway pleads guilty to a 49th murder, that of 20-year-old Rebecca 'Becky' Marrero, whose remains were found in December 2010. He is given another consecutive life sentence.

Identification of Lori Anne Razpotnik ('Bones 17')

Using forensic genetic genealogy, investigators identify the remains previously known as 'Bones 17' as 15-year-old runaway Lori Anne Razpotnik, nearly 40 years after her remains were found near Mountain View Cemetery.

Identification of Tammie Liles ('Bones 20')

The King County Sheriff's Office announces the remains labeled 'Bones 20' have been identified as 16-year-old Tammie Liles through DNA technology, confirming the identity of the last set of unidentified remains associated with Ridgway's 49 victims.

Transport Purpose Revealed in Unsealed Documents

A King County judge unseals court documents from the September 2024 transfer, officially confirming that Ridgway was moved to physically guide detectives to locations of unrecovered victim remains under the terms of his 2003 plea agreement.
