The Pembrokeshire Murders is a three-part Welsh crime drama series that aired in 2021. Based on the real-life investigation of Welsh serial killer John Cooper, the series delves into the chilling murders that took place in Pembrokeshire during the 1980s. The show follows Detective Steve Wilkins as he investigates cold cases from the past, which were solved using modern forensic science and DNA technology. The series masterfully combines suspense, drama, and the real-world application of science to bring a chilling crime story to life.

The plot of the series revolves around the efforts of Detective Steve Wilkins (played by Luke Evans) to solve the murders of siblings Helen and Gwenda, and the subsequent discovery of John Cooper as the prime suspect. The investigation reopens the cold cases of these killings, as well as other crimes committed by Cooper, including rape and robbery. The real breakthrough occurs when DNA evidence, a relatively new forensic tool at the time, links Cooper to the crimes, leading Wilkins and his team to pursue justice for the victims after years of evasion by the killer. The show highlights how technological advancements in forensic science helped uncover the truth long after the crimes were committed.

One of the key aspects of The Pembrokeshire Murders is its focus on the detailed investigation process. The series portrays how Detective Wilkins uses forensic evidence, particularly DNA, to unravel the case. This is an essential part of the story, as the use of DNA analysis to link a suspect to a crime that had remained unsolved for years is a fascinating and realistic depiction of modern-day policing. The attention to detail in showcasing this process adds authenticity to the series and demonstrates how scientific advancements can have a transformative effect on criminal investigations.

The character development of Detective Steve Wilkins is another strong element of the series. Luke Evans delivers a compelling performance as a dedicated, methodical, and compassionate investigator. His portrayal of Wilkins captures the complexity of the character as he deals with both the pressure of solving the case and the emotional toll it takes on him personally. Wilkins’ persistence and commitment to bringing justice to the victims are central to the story’s emotional depth. The series effectively explores his journey, giving viewers insight into the mind of a dedicated detective who refuses to give up.

The portrayal of John Cooper, the serial killer, is both chilling and captivating. Played by Keith Allen, Cooper is shown as a manipulative, sadistic figure who has evaded capture for years. His calm demeanor and ability to deceive others make him all the more menacing. As the series reveals more about Cooper’s past, the audience is taken deeper into his twisted psyche, which adds an unsettling atmosphere to the show. The gradual reveal of Cooper’s dark history keeps the audience hooked, and his portrayal in the series is one of the most haunting aspects of the drama.

In conclusion, The Pembrokeshire Murders is a well-crafted, suspenseful true-crime drama that effectively portrays the investigation into the chilling crimes of John Cooper. With strong performances, particularly from Luke Evans and Keith Allen, the series keeps viewers engaged while shedding light on the crucial role of forensic science in solving cold cases.
