Detectives: My Killer Case is a true crime show that profiles some of the most notorious killers in recent history. Season 1, episode 4 is titled John Sweeney: The Canal Killer.

John Sweeney is a British serial killer who was convicted of two murders in 2011, though he is suspected of several more. Sweeney's preferred method of killing was to bludgeon his victims to death, often with a hammer, and to then dump their bodies in canals or other bodies of water.

The episode begins by introducing viewers to Sweeney, who had a long history of violence and aggression towards women. His ex-girlfriends speak candidly about their experiences with him, describing him as sullen, abusive, and possessive. One woman recounts how Sweeney smashed her head into a brick wall, while another describes how he broke her nose and almost strangled her to death.

The episode then delves into the investigation of Sweeney's crimes, which began in the mid-1990s when the body of a young woman named Melissa Halstead was found in a London canal. Halstead had been brutally assaulted and left to drown in the water. The police had no leads and the case went cold for several years.

In 2000, another body was found in a different canal in London. This time, it was a woman named Paula Fields who had been killed in a similar manner to Halstead. The police began to suspect that they were dealing with a serial killer and launched a massive investigation.

The episode follows the police as they try to piece together the evidence and track down Sweeney. They interview numerous witnesses and acquaintances of the killer, trying to build a profile of him and figure out where he might be hiding. The investigation takes them all over the country, from London to Liverpool to Scotland.

One of the key moments in the investigation comes when the police discover that Sweeney had been arrested in the Netherlands for a violent assault. They are able to obtain a DNA sample from him while he is in custody and match it to the crime scenes in London. With this crucial piece of evidence, they are able to finally arrest Sweeney and charge him with the murders of Halstead and Fields.

The episode goes on to detail Sweeney's trial and eventual conviction. It also explores some of the unanswered questions surrounding his crimes, such as whether he was responsible for other unsolved murders in the area. Viewers will be left with a chilling portrait of a man who was able to commit horrific crimes for years without being caught, and the dogged police work that eventually brought him to justice.
