A JILTED boyfriend who stabbed his ex-girlfriend's new man to death after flying into a jealous rage has been jailed for life.

Daniel McGuiness, aged 22, stabbed 53-year-old Jeffrey Farrow at least 18 times with an eight-inch kitchen knife in front of horrified Derica Weatherby.

He then told his own mum: "I've done the bastard and he's dead."

Mr Farrow and 19-year-old Miss Weatherby, who was previously McGuiness' girlfriend and the mother of his two children, became a couple while the killer was behind bars for assaulting a police officer.

Although McGuiness and Miss Weatherby briefly rekindled their relationship after he was released in August 2006, he became angry that she and father-of-three Mr Farrow were still talking.

His envy culminated in the attack on Mr Fallow at his home on Pendlebury Road, Swinton, on November 9 last year.

McGuiness, of Aspinall Close, Little Hulton, was told by a judge that he would spent at least 15 years and four months in prison after pleading guilty to murder.

"This was a premeditated and deliberate attack," said Judge Clement Goldstone at Manchester Crown Court.

"You went armed to the house and following the attack you made callous remarks to anybody who would listen.

"Jeffrey Farrow was a much-loved father, grandfather, son and brother and no sentence I give you today will help to fill the void that his death has left in the life of many people."

At the time when McGuiness was jailed in May last year for assaulting a police officer, he and Miss Weatherby were living together in Clifton with a young son, and she was expecting their second child, said Alan Wolstenholme, prosecuting.

While he was in prison, Miss Weatherby started seeing Mr Farrow, although she ended the relationship when McGuiness was freed in August, but returned to the victim within weeks and McGuiness moved back to his mother's house in Little Hulton.

Although McGuiness had access to the couple's two children, he became controlling and demanding and eventually took their telly away from Miss Weatherby's new home in Moston, which caused a row between the killer and Mr Farrow.

In the early hours of November 9, McGuiness caught a taxi from Little Hulton to Swinton with an eight-inch kitchen knife stashed up his sleeve.

He burst in to the house through the unlocked front door and launched a frenzied attack on Mr Farrow as he lay on the settee, stabbing him 18 times to his body.

Mr Farrow also suffered three bad cuts to his hands as he tried to defend himself and died later in hospital.

McGuiness got back in to the taxi outside the house and phoned his mother, who he told that he had killed her.

Mr Wolstenholme said that McGuiness also made an admission to police while he was being medically examined after his arrest, telling them: "I just want to tell the truth and do my time for my two minutes of madness."

Stephen Meadowcroft, defending, said: "The defendant had been drinking and taking drugs and was in a highly charged and emotional state."

Mr Farrow's 34-year-old daughter Leigh said: "My dad was giving Derica things that McGuiness couldn't and he was jealous of that.

"Dad was a lovely person who would have done anything for anybody.

"Justice has been done today, but that will never bring my dad back."
