A crane operator from Peckham has been convicted of killing his pregnant ex girlfriend and their unborn baby in Thornton Heath.

26-year-old Aaron McKenzie of Peckham was found guilty of one count of murder and one count of manslaughter in relation to his unborn child, as well as one count of having an offensive weapon, the Crown Prosecution Service (CPS) announced today (Friday, July 10).

McKenzie will be sentenced next week after he broke into the family home of Kelly Fauvrelle in Thornton Heath and stabbed her 21 times as she slept in the ground-floor bedroom they had once shared.

Kelly was 33 weeks pregnant at the time, carrying their unborn child named Riley.

Paramedics battled to save 26-year-old Kelly but she died at the scene in the early hours of Saturday, June 29, last year.

Riley was delivered by caesarean and was taken to hospital but he too died four days later.

The CPS described how Kelly and McKenzie had broken up months prior to the killings and that he had attacked her after learning she was in a new relationship:

"Kelly had ended her relationship with McKenzie more than four months before her death, and made clear that it was over. She had met someone else at Royal Mail where she worked," a spokesperson for the CPS described.

"On the day of the attack, McKenzie had been going through Kelly’s emails and spotted a confirmation email for an online order for some menswear clothing.

"He drove on his motorbike from a friend’s home in Honour Oak to Thornton Heath before sneaking into the house and carrying out the fatal attack just after 3.15am," they added.

Claire Mays, from the CPS, described the killings as "vicious and cowardly" in a statement released Friday: “This was a vicious and cowardly attack on a heavily pregnant woman, which was borne out of jealousy," she said.

“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," she added.
