A woman who was compared to a character from horror movie The Shining was jailed for life today for stabbing her long suffering boyfriend to death during a series of psychotic rages.
Builder's labourer Clare McMahon, 35, used two blades to knife John Robinson up to 30 times after he had earlier likened her mood swings to Jack Nicholson's crazed character in the 1980 film's iconic 'Here's Johnny' scene.
Mr Robinson, 37, who had been asleep in bed suffered fatal wounds to his neck, navel and back when he woke up and then began struggling with McMahon on the balcony of their second floor apartment in Dukinfield, Greater Manchester.
He died at the scene with tests showing he sustained three wounds to the back including one deep 12 cm deep wound which severed an artery and a wound to his throat which cut his windpipe in two.

After the killing McMahon rang her boss in tears say: 'I just couldn't stop myself - I stabbed him all over' and falsely said the victim had come at her with a knife and stabbed her in the hand before she grabbed the weapon from him.
But police inquiries revealed she had been terrorising and tormenting Mr Robinson during their five year relationship and he referred to her as 'that mad bitch' when talking to his family.

The victim's sister told police her brother was seen with scratches on her neck and he told her he was 'frightened and petrified' of McMahon.
During violent rages, McMahon had also smashed a coffee table by throwing it at a wall, had hurled a Christmas tree at Mr Robinson and held a knife to his throat.
She had also banged his head so hard against the wall, Mr Robinson told friends his ordeal was like the 'Here's Johnny' scene from The Shining in which author Jack Torrance played by Nicholson takes an axe to a bathroom door in a bid to kill his wife Wendy.
McMahon herself had even handed a knife to a neighbour in a carrier bag for 'safe keeping' - to stop herself from attacking Mr Robinson.
At Manchester Crown Court, McMahon was convicted of murder after a two week trial and was ordered to serve a minimum of 18 years.
She admitted killing Robinson but denied murder claiming she suffered a form of 'complex post-traumatic stress disorder' due to her being in a 'violent abusive relationship.'
The jury heard the couple had been in a relationship since 2014 but would argue with one neighbours saying they were 'having words with each other' once a month.
The tragedy occurred on May 23 this year after McMahon had been dropped off at home by her boss Daniel McManus who was an ex-boyfriend as well as her employer.
