Known as: Green River Killer
Gary Ridgway grew up in Salt Lake City, joined the U.S. Navy in 1966, was stationed at the Bremerton naval yard in Washington state, married, settled in the Auburn area south of Seattle in the early 1970s, and went to work as a truck painter at a Kenworth dealership near the Port of Tacoma. His hunting ground was a roughly ten-mile corridor of Pacific Highway South (State Route 99) running through the cities of SeaTac, Tukwila, Kent, and Auburn at the southern edge of metropolitan Seattle, in King County, Washington — a stretch of highway lined with adult entertainment clubs, truck stops, motels and street prostitution that police would later describe as the worst stretch of highway in the country for sex-trade homicides. He killed at the rate of roughly one to two women a month in 1982 and 1983, slowed during a stretch of the late 1980s, and is believed to have resumed killing around 1990, continuing intermittently through 2001.
Ridgway picked up victims in his own pickup truck under the pretext of paying for sex, often after approaching them on Pacific Highway South or at an establishment near SeaTac airport after their shifts. He usually drove them to an isolated patch of Green River valley scrub he had identified in 1982 — about three miles south of SeaTac — inside King County, south of Seattle, where he strangled most of them by hand. A few victims were killed elsewhere in unincorporated King County or in his own home. Bodies were disposed of across multiple sites along the Green River and in adjacent ravines, sometimes weighted with rocks. He remembered his killings in unusual detail, often able to direct police back to the precise spot where he'd left years-old remains, and in later years kept keepsakes — a hairbrush, a piece of clothing — from at least some of his victims.
Most of the Green River Killer's victims were young women in their teens and twenties, often runaway girls whose disappearances were not initially reported by family. Wendy Coffield, 16, whose body was found in the Green River on July 15, 1982, was the first victim publicly identified and gave the case its hook. Debra Estes, 15, was the youngest confirmed victim. Lisa Yates, 17, was killed in August 1982 and positively identified only in 2003 after Ridgway's confession. Opal Mills, 23, was murdered in August 1982 and identified only in 2003. Ridgway's victims spanned racial backgrounds and socioeconomic lines but skewed toward women struggling with addiction, homelessness, or street prostitution — one reason so many early disappearances were met with indifference from police and the press. Several victims were found only after 2001, when the DNA backlog from earlier remains produced identifications.
The Green River Task Force, formed inside the King County Sheriff's Office in August 1983 and led for most of its life by Detective Dave Reichert — later King County Sheriff and eventually a U.S. congressman — became the largest serial-killer investigation in American history. Early work focused on matching semen traces recovered from victims to a single offender; by 1985, blood-typing had narrowed the pool to a small percentage of men in the region. The case stalled for nearly a decade while investigators built composite DNA profiles from preserved vaginal swabs and tissue samples. Forensic work intensified after 1999, when the Washington State Patrol crime lab began using new STR analysis on the surviving samples, and in November 2001 DNA from saliva taken from Ridgway in his 1987 traffic stop — preserved by the WSP — matched a surviving victim, putting him under surveillance without his knowledge. Almost all of the 49 convictions began as DNA matches, victims found, or stratigraphic coincidence; the breakthrough confession in 2001 converted years of circumstantial work into a definitive case.
Detectives watched Ridgway for weeks in late 2001 before King County sheriff's deputies arrested him at his Auburn home on November 15, 2001. He was held without bail. On November 5, 2003 in King County Superior Court, Ridgway pleaded guilty to 48 counts of aggravated first-degree murder under a deal that spared him the death penalty in exchange for leading investigators to the remains of still-missing victims. While reading his guilty plea to the court on November 18, 2003, he spontaneously added a 49th murder to his confession — the 1982 killing of Clara Elmore, whose body had already been identified — and the court accepted the addition, dropping his prior 48-count plea to a final 49-count guilty plea. On December 18, 2003, Judge Vetta Lawrence sentenced him to 48 consecutive life sentences without possibility of parole; the 49th sentence was added to running total. The deal was widely criticized by victims' families, in part because of the weak parole protections it offered before the 49th confession.
Gary Ridgway, age 76, is serving 49 consecutive life sentences without the possibility of parole at the Washington State Penitentiary in Walla Walla. He is held in protective custody — believed to be the only prisoner on death row-quality isolation by request of the corrections department after an inmate-on-inmate attack in 2011 — and is one of the longest-incarcerated serial killers in the United States. He has cooperated with law enforcement on the location of additional remains throughout his incarceration, providing maps, return visits to dump sites under guard, and detailed testimony used to close out victim cases and identify remains recovered years after the killings.
Four bodies recovered from the Green River corridor in the early 1980s were never identified despite Ridgway's later cooperation, and have been the subject of periodic DNA-driven re-examination — three were eventually matched in 2020s state-side genealogical work, but at least one remains officially unidentified at the time of writing. King County and Washington State Patrol investigators have also linked the remains of women found in adjacent counties — Pierce, Snohomish — to circumstances consistent with Ridgway's operating territory, but no additional convictions have been brought. Several early Green River Task Force sex-crime investigations of the mid-1980s remain open because the surviving evidence is too degraded for modern STR re-processing.
