On 29 January 2009, dentist Colin Howell walked into a police station in Coleraine, County Londonderry, and admitted to killing his wife, Lesley Howell, and his former lover Hazel Stewart’s husband, Trevor Buchanan, 18 years earlier

Confessions Of A Killer, a new two-part documentary series, features original audio recordings of what Colin Howell told police in 2009.

Broadcast for the first time, these recordings provide a revealing insight into his actions and his decision to make a confession about them near two decades later.

Back in May 1991, it had been thought that the deaths of Lesley Howell and Trevor Buchanan were the result of a ‘suicide pact’. The truth was shockingly different.

Confessions Of A Killer remembers Lesley Howell and Trevor Buchanan, the victims of this story, and the impact of their deaths on some of those closest to them.

It also details Colin Howell’s account of these murders and his then lover Hazel Stewart’s involvement as well as her recent unsuccessful appeal against her sentence and her claim to have been under Howell’s coercive control.

Confessions Of A Killer includes interviews with individuals who knew the victims as well as investigators, journalists, legal experts and people closely familiar with this case and with those most directly affected by it.

Confessions Of A Killer has been made by Below The Radar Television with support from Northern Ireland Screen.

Both episodes are available now on BBC iPlayer.
