Life in jail for man who killed ex after hiding in the loft

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”.
