Ep 28. Traces Of Murder/The Bathtub Killer

In the 28th episode of Cold Case Files season 1, titled "Traces of Murder/The Bathtub Killer," the investigators shed light on the heinous crimes of serial killer David Carpenter, also known as "The Trailside Killer" and "The Bathtub Killer".

The episode starts with the introduction of the killer David Carpenter, who terrorized California for several years during the 1970s and 1980s. The episode provides background information about Carpenter and his childhood, which may have contributed to his violent tendencies. Carpenter was convicted of kidnapping and murder and was serving time in prison for over 10 years when Cold Case investigators reopened his case.

The episode features interviews with the victims' family members, forensic experts, and detectives who worked on the case. One of the primary investigators who was responsible for solving the case was Rick Jackson, who is featured prominently in the episode. Jackson and his team review evidence from past crime scenes, such as blood samples and hair strands, to discover new leads.

The investigators also delve into the challenges they faced while investigating these cold cases. The passage of time had made it particularly difficult to gather new evidence, although technology had advanced since the time of Carpenter's original conviction. The team utilized DNA testing to link Carpenter to crimes that were previously unsolved.

One of the key challenges the investigators faced was establishing a link between Carpenter's different murder cases, as most of his victims had no apparent connection. The team looked at commonalities between the cases, such as time of day or location, to piece together a timeline of Carpenter's crimes.

The episode also highlights the impact that Carpenter's crimes had on the communities he terrorized. His victims' families speak out about the longstanding emotional scars that have arisen from the lack of closure and justice. The episode also stresses the importance of continuing to investigate cold cases, even years after they have gone cold.

Overall, Traces of Murder/The Bathtub Killer is a thought-provoking and compelling episode that examines the tireless efforts of detectives to bring justice to victims and their families. It shows how modern methods and technology can be used to unravel old cases and how community outreach can play a vital role. The episode also offers a sobering reminder of the dangers of violent crime.
