The father of a man who was murdered in Watford three years ago, has made an emotional appeal for information on the whereabouts of his son’s body.

Murray Thompson from St Albans, who was 34-years-old when he disappeared, went missing on April 20, 2010.

James Evans, a remorseless cannabis grower involved in high-level organised crime, was jailed for 21 years for the murder in October last year.

St Albans Crown Court heard that the 24-year-old from Watford killed Murray in a flat in St Albans Road on April 20, 2010 before disposing of his body.

No motive or weapon was ever discovered.

Despite making several appeals in the past, Murray’s parents are no closer to finding their son’s body.

His father Tony Thompson said: "I can’t believe it has been nearly three years. It is still very difficult.

"It is constantly on our minds all the time.

"You can never put anyone to rest if you don’t know what has happened to them. It is still not complete.

"We acknowledge that he has died but without any idea where his body is it leaves it up in the air all the time."

Soon after Murray was reported as missing police launched a murder investigation centred around the flat.

His work van was seen in the area at the time he went missing and was discovered in Robin Hood Drive, Bushey, two weeks later.

Mr Thompson added: "One day I was talking to him and the next day I was never going to see him again.

"It is just a terrible loss. He was my only son.

"We ask people to put themselves in our situation.

"It will be hard if they do find him because it will bring it all back but at least we could live with the fact the we had done something to say goodbye to him."

A Facebook group that was set up around the time Murray went missing is still active, with family and friends leaving tributes and messages regularly.

A reward has been put up for any information that leads to the discovery of his body.

Detective Inspector Jerome Kent from the Beds, Cambs and Herts Joint Major Crime Unit said: "We support Tony’s appeal to find his son, Murray.

"Despite the fact we have secured a murder conviction and justice has been served, we will continue to pursue any lines of enquiry that may lead us to finding Murray.

"Many searches were conducted during the police investigation, which proved negative.

"James Evans, and other involved in the case, have never revealed to police where Murray is, despite being found guilty.

"I am confident there are people connected to this investigation who may also have information about the whereabouts of Murray’s body and I would urge anyone with information to contact us."

Anyone with information is asked to contact Hertfordshire Constabulary on the non-emergency number 101 or anonymously via Crimestoppers on 0800 555 111.
