The victim of an unsolved murder was killed by a ju-jitsu stranglehold, it has been claimed.

Sandy Drummond was found dead on a farm path close to his home at Boarhills, near St Andrews in Fife, on June 24, 1991.

The 33-year-old was found strangled days after he had withdrew money from his bank accounts and quit his job at the Guardbridge Paper Mill.

It has also emerged a cold case review had identified a prime suspect in the killing.

Journalist Michael Mulford told STV News: "I unearthed the fact that, in a cold case review, the police identified a suspect, a serious suspect.

"When they went to check up on him they found that he too was already dead now. The only reason, the police might keep the case open beyond that is if they believe that man had an accomplice or accomplices."

Mr Mulford said from the pathology reports he had seen, he had "no doubt" Mr Drummond was murdered by "the perfect execution of a Japanese stranglehold" from the martial art.

He added: "The information is there, the injuries are entirely consistent with having met that death."

Police Scotland and the Crown Office refused to comment on whether or not a prime suspect in the killing had been identified but confirmed the case is under ongoing review.
