Catching Killers is a four-episode docuseries that examines how some of the most notorious serial killers in American history were finally tracked down by law enforcement. The cases examined are the Green River Killer, the Aileen Wuornos case, and the Happy Face Killer case, which is split into two parts. The first episode is about the Green River Killer, who murdered over 49 young hustlers and buried them in wooded areas in and around Seattle between 1982, he was finally arrested in 2001. The episode starts off with scenes from the special Manhunt Live Search for the killer, hosted by Patrick Duffy. One of the people on the special was Dave Reichert, the lead detective on the task force created by the King County Sheriff’s office to find the killer. He’s one of three investigators interviewed for this episode: Fae Brooks, who was on the task force due to her experience with crimes, and Tom Jensen, who joined the task force due to his ability to organise the evidence that was gathered. The investigation is examined through the use of those interviews, media coverage at the time, and some reenactments. It details how one body after another was found and how the cops had narrowed on a couple of suspects at the time, including Gary Ridgeway. But because they couldn’t pin physical evidence to Ridgeway, the case grew cold until Reichert became sheriff in 1997, when DNA technology had been developed. It still took four more years to nail Ridgeway, based on that evidence.
