A knife-wielding cagefighter was captured on camera running down street chasing a neighbour after murdering his ex.
Andrew Wadsworth, 37, stabbed 32-year-old Melissa Belshaw at her home in Wigan after binging on cocaine and alcohol.
Wadsworth, described as a "violent" and "dangerous" former cage fighter, will be in his late 60s before he will be considered for release after he was convicted of the murder.
After killing Miss Belshaw in the horror attack witnessed by her 13-year-old daughter, Wadsworth fled the house and and took exception to a neighbour who had gone to check the house after hearing the violence.
Wadsworth began to terrifyingly pursue the man, armed with a knife, reports the Manchester Evening News.
CCTV of the incident shows the man in blue desperately trying to hold off Wadsworth's attack as he raises his arms to block the weapon.
But violent Wadsworth repeatedly stabbed the man, with the judge saying he came "close to killing him".
Miss Belshaw's daughter only escaped the house after a brave workman smashed open a window with a hammer to free her as the doors were locked.
Prosecutor Tim Storrie QC said the attack represented a "catastrophe" for the victim, "which left him in fear of his life".
In court, Wadsworth attempted to assassinate Miss Belshaw's character, saying he "lost control" after she made a series of revelations that "humiliated" him.
Before passing a life sentence with a minimum of 32 years, the judge told him: "You had degraded her in life, and you continued to do so after her death."
After sending Wadsworth down, one of Ms Belshaw's supporters in court said 'thank you judge'.
Ms Belshaw's mother paid tribute to her daughter, describing her as a 'beautiful soul, inside and out' who had a 'heart of gold'.
"On May 20 my world fell apart," Jean Mulvaney said in a statement read at Manchester Crown Court.
"I had to hear my 13-year-old granddaughter tell me on the phone that Melissa had been stabbed and that she had died.
"I can still hear that call in my head."
"Nothing will ever be normal again," she continued.
A jury found Wadsworth guilty of murder and attempted murder.
Despite saying that he wanted "no more to do" with Ms Belshaw, he spent the days prior to the murder at her home taking "large quantities" of cocaine.
"You claimed that you had loved her, but the numerous derogatory words used in your text messages to her suggest otherwise," the judge said.
"By contrast, you appear to have had a very high opinion of yourself.
"Your messages display a wholly unwarranted air of moral superiority."
The judge said that on May 20, the day of the murder, Wadsworth had been "badgering her to admit your accusations of misconduct".
Wadsworth stabbed Ms Belshaw multiple times in the bedroom of her home in Upholland Road.
The court was told Ms Belshaw's daughter witnessed "at least some" of the attack.
The child called 999 and her grandmother, in heartbreaking calls played to the court.
When the police arrived, he attacked two officers.
Wadsworth delivered a "roundhouse kick" to the head of one officer, and when he was taken to the police station he punched another officer.
"As a former professional mixed martial arts fighter, you knew exactly what you were doing," the judge told him.
The court was told Ms Belshaw was looking forward to her "dream" of opening a beauty shop.
"The opening of her new shop was her dream and a turning point in her life," her mother said.
"Sadly, she never got to open the shop after all her hard work."
Ms Mulvaney continued: "Our family is broken.
"Even happy events now bring sadness.
"I feel I am going through hell every day.
"I can't sleep, eat, and getting dressed in a morning is hard.
"I will never come to terms with what has happened and will never forgive.
"My heart will never recover as the loss is too great."
Before sending him down, the judge told Wadsworth: "You have displayed no remorse for the death of the woman you professed to have once loved."
