Jason Conroy

In October 2014, 18-year-old Jason Conroy murdered Melissa Mathieson by strangulation at Alexandra House, a residential care home in Bristol providing support for adults with autism and Asperger’s syndrome. The killing was sexually motivated, stemming from Conroy's fascination with necrophilia and his history of predatory sexual behaviour. Avon Coroner’s Court later heard that Conroy, originally from Guernsey and then residing in Windsor, had previously attempted to strangle a teacher to abuse her and had tried to kill his mother, indicating a pattern of dangerous conduct.

Conroy had been transferred to Alexandra House from a boarding school in the Midlands after the incident with the teacher. A forensic psychologist's report commissioned by the school explicitly warned that Conroy posed a physical risk to others due to his sexualised behaviour. Despite this, the care home's managers failed to incorporate these risks into his support plan, which only contained basic information. Staff at the home were unaware of his history, and several reported feeling unsafe around him but were not adequately supported in raising concerns.

Senior Coroner Maria Voisin, in her scathing judgment, described a 'catalogue of failures' by the care home's management, labelling their conduct as 'reckless' and a 'gross breach of duty'. She concluded that Melissa Mathieson 'died as a result of unlawful killing caused by both the act of strangulation and also due to the acts and omissions by the home entrusted with her care'. The coroner emphasised that Conroy should never have been placed in the same facility as Melissa, given his known high risk, particularly to petite females, and the lack of supervision allowed him the opportunity to commit the murder.

Following the incident, Conroy was convicted and jailed for life for the sexually motivated killing. The directors of the company operating Alexandra House pleaded guilty to a health and safety offence and were fined £125,000. Melissa's family, including her parents James and the late Karen Mathieson, expressed profound grief and blamed systemic failures by social services, care providers, and governing bodies for not addressing Conroy's risks or protecting their daughter. Family solicitor Joseph Morgan from Bindmans described the coroner’s findings as 'utterly damning', highlighting the catastrophic multi-agency failures that led to the tragedy.
