The revelation of Colin Howell’s heinous crimes shocked his son, who described how his world crumbled upon learning that his father had murdered his mother, Lesley, and Hazel Stewart’s husband, Trevor Buchanan. Howell engineered the killings to appear as a suicide pact, deceiving authorities in 1991. Only in 2009 did he confess at a police station in County Londonderry, divulging the truth behind the staged suicides.
After admitting to the murders, Howell was sentenced to life imprisonment in 2010, with a minimum term of 21 years. Subsequently, he faced additional charges for sexually assaulting female patients during his dental practice, leading to a concurrent five-and-a-half-year sentence. Moreover, evidence of disturbing child pornography on his computer emerged post his confession, further tarnishing his image.
Currently incarcerated at HMP Maghaberry, Howell awaits potential parole from 2031 onwards. Meanwhile, Hazel Stewart, also serving a life sentence, faced legal setbacks in 2025 when her bid for sentence reduction was rejected. The surviving children of Colin and Lesley shared their emotional journey in the recent ITV documentary, “Killer in the House,” shedding light on the tragic events of 1991.
Reflecting on his tumultuous upbringing under Howell’s oppressive religious beliefs, Seamus Daniel, now a doctor in New York, recounted the chilling atmosphere at home, marked by control and punishment. Despite acknowledging Stewart’s victimhood, he criticized her compliance with Howell’s authoritarianism, emphasizing the impact of their mother’s absence on their family dynamics.
The siblings’ accounts revealed a complex web of manipulation and trauma orchestrated by Howell, whose unraveling began with a family tragedy in 2007. Seamus described the mixed emotions upon learning of his father’s confessions, highlighting the struggle to forgive while seeking closure. Meanwhile, Lauren Bradford-Clarke expressed the distress caused by revisiting the harrowing details of her father’s crimes, as aired in the BBC documentary “Confessions of a Killer.”
The siblings’ poignant narratives underscored the enduring pain and quest for healing stemming from the appalling events of 1991. The documentaries provide a chilling insight into the disturbing past and its lasting impact on the survivors, urging reflection and empathy from the broader community.
