The family of a father-of-three who died after being attacked have offered a £20,000 reward to help catch his killer.
Adrian Cooksey, 50, died nearly two years ago after he was found with head injuries by an off-duty police officer in Spa Road, Melksham, Wiltshire.
In November last year, Thomas Minshull, 20, of Spa Road, was cleared of manslaughter by a jury at Bristol Crown Court.
Wiltshire Police then asked South Wales Police to review its investigation into Mr Cooksey's death and the inquiry was reopened. Now his family have offered a £20,000 reward in the hope of catching the person responsible.
At a police press conference in Melksham, Mr Cooksey's son Adam appealed directly for help in solving the case.
"It is now nearly two years since our dad was killed and although this time has passed, the sadness and devastation that we feel has not gone away," Mr Cooksey said.
"We have decided to offer a reward of £20,000 for information which leads to the conviction of the person who took dad away from us. He was a good man, he was kind and caring and we were a close family. We all miss him and there is not a day that goes by that we don't think about him.
"Someone out there knows what happened to him that night in Spa Road, Melksham. As a family we would like to appeal for anyone who has any information to contact police.
"Nothing can ever ease our pain but to find out who was responsible for his death would mean we can finally start to move on. Whoever knows what happened to our dad, please come forward."
Mr Cooksey, of Trowbridge, died on March 8 last year after he was found earlier that day with head injuries.
