Netflix has added one of the top detective series to its lineup.

The three-part miniseries "Murders in Pembrokeshire," based on the true crimes committed by Welsh serial killer John Cooper, featuring Luke Evans in the lead role, is now available to watch on Netflix. Actor Kyle Lima was one of the first to announce this on his X account.

"I am proud to have been part of this magnificent production," he wrote, describing the project as "brilliant" and "a true crime drama."

In "Murders in Pembrokeshire," Luke Evans portrays Detective Superintendent Steve Wilkins, who led the investigation into two brutal unsolved double murder cases in 2006, which occurred two decades prior to his involvement. The series is based on a 2012 book by Steve Wilkins, the same police officer that Luke Evans plays in the show.

This three-part series boasts an impressive Rotten Tomatoes rating of 82% and has been received by viewers as "one of the best true crime shows."

It first aired in January 2021. In addition to Evans, the cast includes Charles Dale from the series "Coronation Street," Owen Teale from "Game of Thrones," and Steven Meo from "Gavin & Stacey."

The Story of the Pembrokeshire Killer

In December 1985, siblings Richard and Helen Thomas were found dead in their farmhouse at Scoveston Manor, near Milford Haven (Wales). The killer doused the house in gasoline and set it on fire to cover up the crime.

Four years later, the bodies of Peter and Gwenda Dixon were discovered on a coastal path in Pembrokeshire. The perpetrator shot them in the face with a shotgun while they were enjoying a seaside walk on the last day of their summer vacation in Wales in June 1989. He hid their bodies in nearby bushes, stole their money, and withdrew £300 from their accounts.

The culprit of these two double murders, John Cooper, was brought to justice only in 2011, thanks to Detective Sergeant Steve Wilkins, who gathered evidence against him. Notably, he found the blood of one of the victims on the hem of the serial killer's shorts after it had been sewn up to conceal the stain.

Additionally, he noted Cooper's appearance on the game show Bullseye, where he bore a striking resemblance to a police sketch of the killer based on a witness's description following the Dixons' deaths. In an earlier police interview, Cooper claimed that the sketch created in 1989 did not resemble him at all at that time. However, in the series, Wilkins pauses the Bullseye episode precisely where the suspect's profile matched the drawing.

Real detectives, led by Sergeant Wilkins, were able to capture Cooper using advanced DNA technology and scientific evidence. Cooper's long history of crimes already included 30 burglaries and a violent assault, for which he was arrested and sentenced to 14 years in 1998 for burglary and robbery, before being released in 2009.

During the investigation, detectives were able to link the gun used in the robbery to the murder weapon in the Dixon case. He was also found with several items belonging to both sets of victims. In 2011, he was sentenced to life imprisonment.
