A man has been found guilty of stabbing his pregnant ex-girlfriend in a jealous rage, killing her and their baby. Aaron McKenzie, 26, broke into Kelly Fauvrelle’s bedroom as she slept and stabbed her 21 times, causing catastrophic injuries, the Old Bailey was told. Their son, Riley, was delivered by caesarean section but died in hospital four days later. McKenzie killed Fauvrelle, a 26-year-old Royal Mail worker, in a “vicious and cowardly” attack after their “toxic” relationship ended, the court heard. He denied responsibility, claiming a man named Mike, to whom she owed money, carried out the attack. But a jury found McKenzie, a crane driver from Peckham in south London, guilty of the murder of Fauvrelle, who was 33 weeks pregnant, the manslaughter of Riley and possession of a knife. Fauvrelle’s relationship with McKenzie, with whom she shared an interest in motorbikes, had ended early last year, the court heard. In February, McKenzie messaged that he was feeling “not needed, not wanted, unimportant and lost” as he appealed to her. Fauvrelle told him he needed professional help, saying: “Until u get the fact I don’t want to be with you anymore ... I will no longer speak or see you unless is about the baby” (sic). Last March, Fauvrelle told McKenzie’s mother that the relationship was “toxic” but she would not deny him access to their child. At about 3.15am on 29 June last year, an intruder broke into Fauvrelle’s family home in Thornton Heath, south London, through patio doors. After the attack, McKenzie pretended to have nothing to do with it, the court heard. He went to the hospital where medical staff were trying to save the life of his child, “posing as a victim”, the court heard. McKenzie lied to police and did not tell them that he had spent more than an hour before the killing accessing and reading his ex-partner’s emails. He continued to deceive officers, hospital staff and Fauvrelle’s family until he was arrested and then he confessed. Claire Mays, from the Crown Prosecution Service, said: “This was a vicious and cowardly attack on a heavily pregnant woman, which was borne out of jealousy. Aaron McKenzie murdered his ex-girlfriend and in turn also killed their child Riley. “Just hours after carrying out the attack, McKenzie went for a driving lesson as if nothing had happened. “The prosecution evidence included a confession McKenzie had made to police officers taking responsibility for the killings before he decided to change his story and blame his actions on his learning difficulties and depression. “By choosing to take this tragic case to trial, McKenzie took the family of his victim through the heartbreak and ordeal of listening to all of his lies and the damning evidence against someone who had once been a part of their family. “Although nothing can bring back Kelly and Riley, I hope these convictions provide some comfort to the family. Our thoughts remain with them at this difficult time.” McKenzie will be sentenced on 17 July.
