Green river homicides investigation

Green river homicides investigation

On July 15, 1982, the body of Wendy Lee Coffield was found in the Green River. Within a month, four other bodies were found on the riverbank:  Debra Lynn Bonner, Marcia Faye Chapman, Opal Charmaine Mills and Cynthia Jean Hinds.  Thus began one of the longest and largest serial murder investigations in United States history. Eventually, the deaths of at least 48 women would be linked to the Green River killer.

Our investigation continued for decades. Over time, the combination of advancing technology, science,  and determined investigative work advanced the case until an arrest was made in 2001.

  • November 2001: Gary Leon Ridgway was arrested and subsequently charged with the murders of Cynthia Jean Hinds, Marcia Faye Chapman, Opal Charmaine Mills and Carol Ann Christiansen.
  • April 2003: Ridgway was charged with three additional murders (Wendy Lee Coffield, Debra Lynn Bonner and Debra Estes).
  • June 2003: In exchange for the prosecutor not seeking the death penalty, Ridgway agreed to plead guilty to all murders that he committed in King County. He agreed to provide complete, truthful and candid information concerning the crimes that he had committed in King County and answer all questions during interviews conducted by the detectives or the prosecuting attorney.
  • November 5, 2003: Gary Leon Ridgway pled guilty to 48 counts of Aggravated Murder in the First Degree.

Unidentified Victims

Gary Ridgway admitted to killing of all of these women, but could not supply any significant information that would assist in the identification of these women. The clay reconstructions were done by National Center for Missing and Exploited Children (NCMEC) to assist us in identifying the women. Hair styles are only a ‘best guess’.

Victim #10:
White Female found 3/21/1984 in the Burien area off of Des Moines Memorial Drive. This victim could be as young as 12 years of age. Ridgway implied that the victim was killed in the spring or summer of 1983.
Victim #17:
White Female found 1/2/1986 near Mountain View Cemetery in Auburn. Age estimated between 14 and 18 at the time of her death. Ridgway implied that the victim was killed in the spring or summer of 1983
Victim #20:
Unknown race female found 8/21/2003 off Kent-Des Moines Road at a site pointed out by Ridgway.  Ridgway described her as white, possibly with a brother named 'Mike.'  Her age is estimated as between 20 and 30.
