Jilted partner strangled high-flyer

Mercedes executive Kirsty Wilson was murdered by Alan Jermey

A jealous martial arts expert who strangled his partner after learning she planned to leave him for another man has been found guilty of murder.

Alan Jermey, of Surrey, was "obsessive" about Mercedes executive Kirsty Wilson, the mother of his two children, and could not stand to let her go.

Jermey, a car salesman with a black belt in kung fu, used his skills to throttle her, leaving few external injuries.

He set her body alight to try to make it look as though she had died in a fire but the blaze failed to take hold.

Jermey was remanded in custody to Monday when he will receive a life sentence after the judge decides on the minimum term he should serve.

The killer hatched a cold-blooded plan to kill her after learning she planned to leave him for her married boss Simon Goddard.

Miss Wilson signalled an end to their nine-year relationship when she told him: "I can't see us spending the rest of our lives together."

But Jermey was not prepared to lose her, their two daughters, or the four-bedroom house where they lived together in Woking. He secretly ordered a 100,000-volt stun gun over the internet so he could knock her out before killing her.

After pouring petrol over her, he arranged her body to make it look as if it had been set alight and clambered on to an extension roof with their two daughters as one of them cried: "I want mummy."

Miss Wilson's parents Peter and Sandra Wilson, who both wept as they gave evidence at the trial, described her as popular and beautiful, and "the kind of woman who turned heads". They said the real victims were their two granddaughters, who had been deprived of their mother.
