The family of a cafe owner murdered at his business in Kent two years ago have renewed their appeal for information.
The body of Andrew Cresswell, 51, from Pluckley, was found at Unit 2 on the Pivington Mill industrial estate, in Pluckley, on 11 November 2008.
He had been hit over the head with a weapon, and one theory investigated by police was he had disturbed intruders.
His sister Sue Harris urged anyone who knew anything that could help catch the killers to come forward.
"It could happen to you one day. It could be your brother," she said.
Three men arrested on suspicion of murder soon after the killing were later released.
Mr Cresswell lived on the premises where he ran the cafe and also had a workshop.
His family have now had a plaque erected in his memory at Lashenden Air Warfare Museum in Headcorn, where he was a member.
"We're also going to have a little plaque put on the wall at Pivington for him," Mrs Harris said.
