A JEALOUS lover knifed a mother-of-three through the heart at her Sheffield home to stop her leaving the city and starting a new relationship, a court heard.
Dawn Backhouse, aged 31, was allegedly stabbed with a chef’s knife in the kitchen of her home in Langsett Grove, Walkley, by 45-year-old Mark Hatter.
Sheffield Crown Court heard Dawn had moved to Sheffield from Maidstone, Kent, in 2008, with her third husband, Andrew Backhouse. Around the time the marriage broke down, Dawn began a sexual relationship with Hatter, of Hammerton Road, Hillsborough.
She told her cousin that Hatter wasn’t a serious boyfriend and she had begun a relationship with David Brunger, a man from her home town.
On the night of her death last June, Hatter became “increasingly frustrated” when Dawn failed to reply to his texts and phone calls, took a knife from his kitchen and climbed through Dawn’s bedroom window, the court was told. Neighbours heard a man shout: “Die, die.”
Hatter claimed Dawn had stabbed herself in the arm and the fatal injury was caused accidentally when he tried to wrestle the blade from her. When Dawn said she was dying, he plunged the knife into his own chest.
Richard Mansell QC, prosecuting, said: “He was plainly jealous and unable to accept she no longer wanted to be with him and he either could not or would not let her go.”
Hatter was prescribed medication for depression and suicidal thoughts a week before the killing, jurors heard. The trial continues.
