A reward has been offered to find those responsible for the murder of a man killed in his Essex home more than four years ago.
Michael Shipton, known locally as Joe, was found on 25 March 2006 at his house in The Plashets, Sheering, near Harlow.
The 61-year-old died of head injuries after being struck several times with a blunt instrument.
A £5,000 reward has been put forward by Crimestoppers for information leading to a conviction.
It comes two days after Essex Police renewed their appeal for information and issued an artist's impression of the victim.
He was discovered after a friend called at the house where he lived alone and found him dead.
Police found no evidence that the attacker forced their way in, but said they were keeping an open mind on whether Mr Shipton knew his killer.
He had been made redundant from his job in the 1970s and did gardening and other odd-jobs for cash.
