Wendy Stephens: Green River Bones 10 Solved via IGG

Restoring Humanity to Bones 10: How DNA Doe Project and King County SO identified Gary Ridgway's youngest victim after 37 years.

Archival Case File Banner: Wendy Stephens (
SECTION 1: THE OFFICIAL CASE RECORD (VERIFIED FACTS)
Official Case Date March 21, 1984 (ID'd December 2020)
Discovery / Last Seen Location Highline Soccer Complex, SeaTac, King County, WA
Demographic Profile White Female Adolescent, 14 Years Old (5'2", Brown Hair)
Anthropological Age Estimate 14 Years Old (DOB: 1968)
Primary Investigating Agency King County Sheriff's Office & DNA Doe Project
Forensic Identifiers Available Ligature Strangulation Trauma, High-Density SNP Profile, Ridgway Confession

On March 21, 1984, skeletal remains were discovered in a dense swampy thicket adjacent to the Highline Soccer Fields near South 146th Street and 16th Avenue South in SeaTac, Washington. Designated by detectives as "Bones 10," the remains were situated in the heart of the killing grounds utilized by Gary Leon Ridgway, the infamous Green River Killer. For thirty-six years, she remained a faceless statistic among Ridgway's admitted forty-nine murders.

Discovery, Scene Architecture & Ridgway's Confessions

The burial site in SeaTac was a known cluster dump area. The remains of another young woman, Cheryl Wims, were located just yards away. During his 2003 plea agreement with the King County Prosecuting Attorney's Office, Ridgway admitted under oath to murdering the girl known as "Bones 10" between 1982 and 1983. He described strangling her and discarding her body in the wooded buffer between the soccer fields and the roadside.

Forensic anthropologists estimated the victim was between 12 and 18 years old, standing approximately 5 feet 1 inch to 5 feet 5 inches tall. She had suffered perimortem neck trauma consistent with ligature strangulation. Because she was a runaway who had traveled cross-country, local Pacific Northwest missing persons registries yielded zero matches.

SECTION 2: PROMINENT COMMUNITY THEORIES & ANALYTICAL HYPOTHESES
Investigative Ethics & E-E-A-T Guarantee: This analytical section examines documented community theories, crowdsourced timeline comparisons from verified cold-case forums (Websleuths, Reddit r/UnresolvedMysteries, Doe Network), and geographic distribution models. In strict accordance with our nonprofit charter, no living unindicted private citizens are named or accused. All hypotheses evaluate physical markers, transportation corridors, and anatomical evidence.

The DNA Doe Project Resolution & Juvenile Predator Patterns

In 2019, King County Cold Case Detective Mike Mellis partnered with the DNA Doe Project to perform advanced whole-genome sequencing on degraded petrous bone samples. Despite extensive postmortem decay from over three decades in wet Pacific Northwest loam, laboratory technicians successfully generated a high-density SNP profile.

Volunteer genetic genealogists triangulated fifth- and sixth-degree cousin matches across GEDmatch and FamilyTreeDNA, steadily reconstructing extensive family trees rooted in Denver, Colorado. In late 2020, the team identified Wendy Stephens, who had vanished from Denver in August 1983 at just 14 years old.

Official reference DNA submitted by Wendy's surviving mother provided absolute mathematical confirmation. Wendy Stephens is believed to be the youngest confirmed victim murdered by Gary Ridgway. Her identification underscores how adolescent runaways in the early 1980s fell prey to predatory cross-country truckers and local serial offenders along the Pacific Highway corridor.
