Howell, 65, and his former lover Hazel Stewart, 62, murdered their respective spouses Lesley Howell, 31, and police officer Trevor Buchanan, 32, in May 1991. He first told his second wife Kyle Jorgensen in 1998 that he had killed both victims, who were found in a fume-filled garage in Castlerock, County Londonderry. Now, a new episode of 'Confessions of a Killer' on BBC Two this Sunday reveals footage of Ms Jorgensen speaking to detectives just hours after Howell's arrest. Howell first told Ms Jorgensen in 1998 that he had murdered them and was thinking about handing himself in to police. The programme also features audio of Howell telling police about confiding in Ms Jorgensen ten years earlier.
