Alaina announces upfront that this is a four-part series because Gary Ridgway's case is so vast. She explains that Ridgway was long considered the most prolific serial killer in American history but has since been surpassed by Samuel Little, who killed at least 93 known victims. The hosts issue a frank content warning: the episode contains graphic descriptions, rape, and victims as young as 15 and 16 years old. Ash and Alaina agree to skip any lighthearted intro business and dive directly into the case, setting a sober, respectful tone from the start.

Wendy Coffield's story is one of quiet desperation: after her parents divorced, she moved with her mother from a farm to subsidized housing and began drifting. After two theft arrests — including stealing food stamps to help her mother — she was placed in a foster home. On July 8th she left to visit her grandmother and never arrived. A week later, two boys on bikes spotted her nude body tangled in branches along the Green River, her pants tied tightly around her neck. The only meaningful physical evidence was an unusual industrial spray paint on those pants, which led nowhere. Detectives knew she had been sexually assaulted, but a week in the water had washed away nearly all forensic evidence. Wendy's case went cold almost immediately — just one more tragic story in a region already too familiar with young women disappearing.

On August 12, 1982, P.D.J. Meat Company employee Frank Leonard stepped outside for a cigar break and noticed the water churning strangely below the old slaughterhouse — then realized he was looking at a woman's body. By the time officers arrived, nearly the entire factory crew had gathered at the scene. King County Detective David Reichert, already a hardened veteran who had survived being stabbed in the neck multiple times while rescuing a trapped woman, arrived and found 21-year-old Deborah Lynn Bonner face down in the current, her hands raised as if waving or reaching for help. The last known sighting of Deborah was July 25th, when she left the Three Bears Motel to 'catch some dates.' The Bonner family pointed detectives toward her boyfriend Martin as a possible suspect. Barely had Reichert begun to pursue that lead when the next report came in.

Three days after finding Deborah Bonner, a rubber raft treasure hunter on the Green River came upon two nude women half-submerged along the bank. He spotted a young man on the shore who waved politely, then walked to a pickup truck and drove away. When Reichert arrived and walked the banks himself — crawling through tall weeds on his hands and knees — he came face to face with a third body: a teenage girl, partially dressed, her pants tied around her neck in the same fashion as Wendy Coffield's. The three victims were identified as 31-year-old Marcia Chapman, 17-year-old Cynthia Hines, and 16-year-old Opal Mills. At a press conference the following day, officials confirmed to the public that one suspect was likely responsible for all five deaths, making it official: there was a serial killer on the loose in the Tacoma area.

Alaina takes time to tell each victim's story with care. Marcia Chapman was a mother of three young children living on the SeaTac Strip who left her apartment telling her children she'd be back soon. Cynthia Hines, 17, had a self-described 'protector' who was really a pimp and who watched her get into a black Jeep without writing down the plate. Then came Opal Mills — a 16-year-old who spent her time in church and with her family, a curious outlier with no sex work history whatsoever. The press, however, made no such distinction, and a school official told a reporter that 'Opal's pimp picked her up from school the day she went missing.' That pimp? Her brother, who was simply making sure she got home safely. The episode also reveals the grotesque detail from Marcia Chapman's autopsy: the killer had placed small stones inside her so tightly they required surgical removal.

The formation of a 25-person task force — King County's largest investigation since the Bundy slayings — should have represented a turning point. But investigators were so consumed by their five known victims and the tip hotline that they never checked open missing persons cases, which might have revealed the killer's weekly pace. Giselle LaVorne's story is perhaps the most damning example: she disappeared July 17th, exactly between Wendy Coffield and Deborah Bonner. Her partner James Tyndall filed a report, offered investigators a list of her regular clients, and begged them to take it seriously. Officers told him she'd turn up. She did — nude, with men's socks tied around her neck, found in underbrush near the airport months later. The episode also explores the systemic failure of the era: 600 teenagers lived on the streets of King County, and police operated on the assumption that missing adults, especially sex workers, had simply chosen to vanish.

Ash kicks off the break by mentioning how much she missed her dog Dolores while traveling.

Sixteen-year-old Linda Rule had dropped out of school and was sharing a motel room with her 24-year-old boyfriend Bobby. On September 26th, she told Bobby she was going to Kmart before trying to make some money, and never came back. Bobby kept meticulous notes of his search and turned them over to police, but Linda effectively vanished. Her skeletal remains were found in January 1983 near the Northgate Hospital construction site, identified through dental records. Because she wasn't found near the river and no cause of death could be confirmed, Seattle Police initially didn't classify her as a Green River victim. Meanwhile, the task force, run primarily by David Reichert and former sex crimes detective Faye Brooks, continued fielding calls from parents with missing children as the Green River Killer appeared to go quiet through the winter.

In the fall of 1982, the Green River Task Force enlisted the FBI's Behavioral Analysis Unit — the group immortalized in the show Mindhunter, which Alaina briefly laments was cancelled. The resulting profile pointed to a man familiar with the area who had contact with sex workers. That description fit Melvin Foster, an unemployed cab driver who had inserted himself into the investigation by offering to be an informant. He failed a polygraph and became the primary suspect. But critical details didn't add up: a March 1982 knee injury would have made carrying bodies physically impossible, and his car was broken down around the time the victims were being transported to dump sites. Within months, Foster was ruled out entirely, and the task force was right back where they started — seven victims, no suspects.

Carol Ann Christensen was 22 years old, a mother of five, and had just secured her first waitressing job after months of unemployment. On May 3rd, 1983, she disappeared while walking to work. Her body was found five days later in Maple Valley, about 20 miles from the strip — a disturbing departure from every previous Green River crime scene. The body had been posed: hands folded across her chest with ground sausage placed on them, two gutted trout laid across her throat, an empty wine bottle across her stomach, and a paper bag over her head. Her bra was on inside out and her shoes were unlaced. Investigators debated whether this was a different killer entirely, but the washerwoman wrinkles on her skin suggested recent immersion in water — a Green River signature. A paper bag was traced to a grocery store near the killer's known hunting grounds. Investigators concluded the elaborate staging was likely Ridgway's attempt to throw off detectives, and it nearly worked.

Shonda Summers left her family in San Diego to live with her father in Seattle, but after being arrested on a prostitution charge and her father refusing to post bail, she took off with her boyfriend. In October 1982, she vanished — and it took nearly a month for anyone to even file a missing persons report, with no one able to clearly recall the last time they'd seen her. Her badly decomposed body was found in August 1983 by an apple-picking couple near the strip, close to where Giselle LaVorne had been discovered the year before. Advanced decomposition made it impossible to determine cause of death. The task force added her to the list as victim number 9. But Alaina drops the chilling corrective: Shonda was actually victim number 12 — the true order of Ridgway's crimes wouldn't be untangled for years.

Alaina caps Part 1 by noting that by the end of 1983, the Green River Killer was far from done — and lays out his ultimate known tally: convicted of 49 murders, he later confessed to 65. The hosts share a moment of disbelief that such an 'unremarkable little rat' could operate for so long, from the early 1980s into the 1990s. Ash observes that the idea of his face being the last you'd ever see is uniquely horrifying. To offer listeners a palate cleanser before signing off, Ash shares a fun fact: the average person in Sweden eats about 22 pounds of chocolate per year, prompting a brief, warm tangent about Swedish gummy candy and a recommendation to seek out Sweetish Candy.

The episode ends with a Capella University spot targeting lifelong learners and degree-seekers ('What can't you do? Visit capella.edu'), followed by a quick plug from Angie co-founder Angie Hicks, promoting Angie as the platform to find trusted local contractors for home projects. With that, the episode formally closes out.
