Michael Porchetta, 28, might never be released after he brutally stabbed Aimee Cannon, 26, to death at her home in West Calder, West Lothian, on May 7, 2022.
He has been detained in hospital indefinitely.
The deceased who was a beautician had previously spurned his advances insisting they were just ‘pals’.
Her father Vince discovered her body when he came to her house the next day.
The post mortem concluded that she died of multiple sharp force injuries.
‘She had at least 45 stab wounds and multiple clean cut wounds on her scalp as well as both hands.’
Porchetta stayed with his uncle Robert Nicoll, 59, and sister Gabriella, 29, after their parents passed away.
Porchetta had been due to stand trial for murder but was deemed unfit as a result of a learning disability.
An examination of facts hearing instead took place to look at the circumstances of the incident and Porchetta’s mental state at the time.
Lord Mulholland concluded in November last year that Porchetta ‘beyond reasonable doubt’ carried out the attack.
After hearing evidence from two psychiatrists who had compiled reports on Porchetta, Lord Mulholland imposed an indefinite compulsion order for him to remain at the State Hospital in Carstairs.
The judge told him: ‘I found that you murdered Aimee Cannon – for whatever reason, only you will know.
‘You subjected her to a cowardly, vicious and frenzied attack.
‘She was defenceless as you were armed with a knife or knives. It is clear from some of her defensive injuries and her broken nails, she fought for her life.’
He added Porchetta had ‘deviously tried to cover his tracks’ including getting rid of the victim’s mobile phone and trying to clean blood from his trainers.
