An artist’s impression of a man whose badly battered and burned body was dumped at the side of the M45 in Warwickshire has been released by police.

The drawings were completed by a forensic artist, using still photographs of the body and scanned images, in a bid to discover the identity of the man who remains unknown more than a week after the discovery of his body.

The victim, who was murdered before his body was set alight, was discovered naked in a ditch at the side of the motorway near Dunchurch during the afternoon of December 30.

A week on from the grim discovery, murder hunt detectives from Warwickshire Police have stepped up their investigations. Posters, banners and Bluetooth technology at nearby service stations are among the tools being used to try and establish the identity of the man and the latest artist’s impression is to be distributed internationally.

DNA information and palm prints, which is a relatively new use of forensic technology, have been sent to Interpol, the national Missing Persons Bureau, and police forces throughout the UK.

The victim suffered substantial head injuries and was dead before he was set alight on the motorway.
