A cash reward is being offered for information relating to the death of a Gloucestershire man a year ago.
Police are treating the death as unexplained
Shaun James, 32, died on 15 December 2002 from his injuries after being found seriously hurt by the side of the road in Steam Mills, Cinderford.
Gloucestershire Police are now offering a £5,000 reward for information that leads to an arrest and conviction in connection with Mr James' death.
It is believed Mr James was involved in a hit-and-run incident, although police are still treating his death as 'unexplained'.
A post-mortem examination found Mr James had multiple injuries to his body.
Detective Chief Inspector Neil Kelly said: "There may be people who have not previously come forward to speak to us, and perhaps that is because they believe they saw nothing that would help us in any way.
"However, we cannot leave any stone unturned in this investigation as we are still determined to ascertain exactly how Mr James met his death.
"We will treat any information we receive sensitively and in the strictest confidence."
