During the attack, Kelly Fauvrelle’s family awoke to hear her screams, as Aaron McKenzie stabbed her 21 times in her bed.
Aaron McKenzie, 26, from Peckham, south London, has been given a life sentence with a minimum term of 35 years for the murder of his pregnant ex-girlfriend, Kelly-Mary Fauvrelle, also aged 26.
The sentence comes with a further 20 years for the manslaughter of their unborn child, Riley.
McKenzie was also given three years for possession of a knife with all the sentences to run simultaneously.
The court heard on Friday, July 17, 2020 how the crane operator had broken into Ms Fauvrelle’s home in Thornton Heath in the early hours of 29 June last year, before stabbing her 21 times as she slept in her bed.
Her family, who lived in the same property, awoke “to the noise of her screams,” Judge Mark Lucraft QC said as he handed down the sentence for the “ferocious” attack.
“It’s clear from all the evidence this was the most vicious and deliberate killing, which is a cowardly response to the victim.” he added.
The couple’s relationship is said to have ended early last year, with Ms Fauvrelle, who was 33 weeks pregnant at the time of the attack, telling her ex-boyfriend he needed professional help.
She messaged him: “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.”
Their son, Riley, was delivered by caesarean section shortly after the attack, but died four days later.
The jury took less than three hours to find McKenzie guilty on Friday, and the killer gave the judge a thumbs up as he was sent down.
