The relationship of James Todd and David Fielding has been described as tempestuous and volatile.
The two men who lived in Clayton-le-Moors had only met at a Canal Street bar in Manchester in April 2009.
Seventeen months later chef James Todd – who referred to himself and was known locally as the ‘Salford Soldier’ – was stabbed through the heart by his partner Fielding.
The 27-year-old’s body lay in the flat the young pair shared on Rutlands Close for three weeks and was badly decomposed when the police found it in September 27 last year.
After a judge jailed Fielding for life Detective Superintendent Neil Hunter spoke of the issues surrounding domestic violence.
"James and his partner David Fielding shared a tempestuous relationship punctuated with episodes of violence of which James was invariably the victim," he said.
"The same sex relationship is no different than any form of domestic abuse.
"It’s extremely serious and was certainly present in this relationship.
"I’m convinced that the majority of the bullying and violence and all the control was inflicted by David Fielding. It wasn’t two-way domestic abuse.
"Although there were elements of threats from James Todd I’m convinced he was the one living in fear of intimidation."
DS Hunter says his team are sure James Todd was stabbed in the heart by Fielding on Sunday, September 5.
He said: "On that Sunday they were exchanging texts to each other while Fielding was inviting another man he’d met on the internet to the pub where James was going to be.
"This is maybe indicative of what he was like as a man.
"Immediately after the offence Fielding showed his true colours, disappearing off to Kent to visit a relative and then visiting the Lake District and Birmingham, while no doubt planning and inventing a story in an effort to excuse his wicked, fatal and violent attack.
"He also used James’ cash card and phone after the killing and, quite remarkably, even returned to the flat to recover a computer while James was still lying dead in the bedroom.
"Fielding even closed James’ Facebook account down in a despicable attempt to cover his tracks."
In one incident Fielding is said to have bitten off part of Mr Todd’s ear. DS Hunter also said Mr Todd had old stab wounds to both shoulders.
He added: "The web of deceit that Fielding wanted us to believe were all quite unsavoury to besmirch James’s character.
"Let’s not forget that Fielding wanted people to believe that James was a person who he had previously been affectionate towards.
"Fielding’s attempts to hoodwink the jury failed miserably and I am pleased that they saw through his efforts to escape being brought to justice."
