A jealous lover who hid overnight in his ex-partner’s loft before he throttled her to death has been jailed for life.
William Mack, aged 39, laid in wait for more than 16 hours and then caught Leanne Wall, 36, by surprise soon after she awoke.
Fuelled by paranoia that she had cheated on him at a party, he headbutted her and then strangled her with a belt and his hands in what the sentencing judge said was “a callous pre-meditated and planned killing”.
He threatened to kill Ms Wall the day before and made clear his intentions to a friend in “chilling” text messages, Manchester Crown Court heard.
In one, he wrote: “I am going to do her in. We both lose. I will get locked up but at least I will still have a life.”
When Ms Wall returned from work on February 11 she suspected Mack had been in her house as the kettle was warm and some of her clothes were missing.
She texted him — unaware he was in the loft with a sleeping bag and food and drink — and later rang a friend to say she had heard noises in the house but thought it was her dog.
Rob Hall, prosecuting, said the pair first met in 2009 shortly after Mack ame out of prison after being jailed for wounding.
Her family, he said, could not understand what attracted Ms Wall, a business risk manager, to the unemployed regular cannabis smoker, but they supported her nonetheless.
