Stephen Akinmurele

Victims The victims in the case were all senior citizens; the lead investigator in the case noted that Akinmurele had a "pathological hatred" of old people. He was dubbed the "Cul-de-Sac Killer" due to his choice of elderly victims living in quiet suburban streets.

His first two known victims were Eric Boardman, 77, and his wife Joan Boardman, 74. Both were murdered at their home in Blackpool on 30 October 1998. One of their daughters discovered their bodies. Eric, who had been beaten to death, was found under a wardrobe in the hallway of their home. Joan had been strangled to death and was left on the living room floor. Akinmurele used batteries bound together to make a cosh, which was found beneath Eric's body. Akinmurele was arrested and charged with their murders on 1 November 1998.

In the months following his arrest, he was charged with 3 further murders. In November 1998, he was charged with the murder of Jemimah Cargill, 75, who had previously been his landlady. She died in a flat fire in Blackpool in October 1998, prior to the murder of the Boardmans.

In November and December 1998, following a joint investigation between Lancashire and Manx police, he was charged with 2 murders that had taken place on the Isle of Man. First, he was arrested in connection with the murder of Dorothy Harris, 68, who was killed in February 1996. Harris, who had been partially blind and deaf, was found after a house fire at her home in Ballasalla. The second murder was of Marjorie Ashton, 72, who was found strangled in her home, also in Ballasalla, in May 1995.

A suicide note was found in his pocket after his death, with Akinmurele having written: "I know it's not right always thinking like this but it's always on my mind. I can't help the way I feel, what I did was wrong — I know that and I feel for them — but it doesn't mean I won't do it again. I'll keep on having this feeling I'm going mad because I can't take any more of this and that's why I'm saying goodbye." He had also written to this mother: "I couldn’t take of the feeling like how I do now, always wanting to kill".
