A drug dealer who bore a grudge against a Manchester criminal has been found guilty of his murder.
Derek McDuffus was a drugs dealer
Derek McDuffus, 41, of Merseybank Avenue in Chorlton, Manchester, denied murdering Desmond Noonan, 45.
But he was convicted on Monday at Preston Crown Court and will be sentenced on Tuesday.
Shajahan Cooke, 39, of Chorlton, was also convicted of attempting to pervert the course of justice and sentenced to 18 months in prison.
Cooke, who had denied the offence, was convicted on charges relating to attempts to destroy evidence and provide an alibi for her partner McDuffus.
The court had been told Desmond Noonan, who was known as Dessie, managed to phone his wife for help after suffering massive bleeding caused by a stab wound to the stomach.
His body was found outside a house on Merseybank Avenue, Chorlton, in March this year.
McDuffus was a dealer who had supplied crack cocaine and Mr Noonan had gone to him in the past for the drug.
Noonan was murdered days before he appeared on a channel Five documentary in which he bragged about being untouchable by the police and claimed to have killed more than 20 people.
Det Ch Insp Shaun Donnellan, who led the investigation, told people not to copy Noonan's lifestyle despite its apparent glamour.
"I would urge those attracted to such a lifestyle to consider the pain it would cause their family and friends, and turn away from it before they end up dead or in prison," he said.
"No matter who the victim, Greater Manchester Police takes murder very seriously and we will work tirelessly to bring justice to the victim and their family."
