Grandson murdered wealthy grandmother and staged fire to conceal killing

Joshua Powell, 27, murdered his 96-year-old grandmother Emma Finch in her Hampshire home on 17 May 2024, strangling her whilst she slept before setting fire to her bungalow to disguise the killing as an accident. The Tesco cashier, who was in significant debt, had deliberately cultivated a close relationship with his wealthy grandmother to position himself as her beneficiary. The case exemplifies a calculated betrayal of trust, as Powell had built a reputation as a devoted grandson visiting weekly to help with shopping and play Scrabble.

When interviewed by police, Powell exercised his legal right to silence and refused to answer any questions, despite direct allegations about the murder. Investigators established the fire was staged through forensic evidence: it was unusually confined to the bed, spent matches at the scene differed from others in the house, and a post-mortem examination revealed Ms Finch died from neck compression before the fire started. CCTV footage contradicted Powell's claim of being asleep at home, showing his car left his address at approximately 2am on 17 May, whilst phone and social media data confirmed he was active at the time. Powell was sentenced to life imprisonment with a minimum term of 26 years in November 2025.
