A year has passed since a Sunderland man was found dead at his home - and police are urging the public to help piece together his final movements.
David Wilson, who was 49, of Southwick Road, Sunderland, was found dead at his home on December 14 last year.
Police are continuing work to find the person responsible for his death - and detectives have spoken of a call made to police in the early hours of December 14 where a man says he is lost and is next to the Halfway House pub, near to the street where Mr Wilson lived.
The man made the call to police at 4.41am on this day - and told them he was lost and needed to know how to get back to Gateshead from Sunderland. He said his lift had been unable to collect him as had been arranged.
Police want to speak to the caller as he was in the area at the time, and may be able to assist officers with their inquiries. They are also appealing for the person expected to pick the caller up from the Southwick area to make contact with them.
A robbery, believed to be connected with the incident, is also being investigated.
At 4.18am on December 14 last year, police received a report from a man saying he had been mugged near to the Post Office cash machine in Southwick Green.
Detective Inspector Mark Ord said: "This has obviously been such a difficult year for David's family and I want to commend them for their support and patience during this investigation.
"It is a very complex investigation with many parts of the puzzle we are trying to piece together. We need the help of the public to come forward with any information, no matter how small or insignificant they may think, as it may just be the final key detail we need to solve this murder.
"I would urge the man who made the call to police at this time to contact police as he may have information which could help police with the investigation. It is believed he was in the area of Southwick Road at the time and may have seen something suspicious.
"I would also ask the person who had arranged to give the man a lift home to contact us as, again they may have information.
"We are still investigating a robbery which we believe was connected to the incident and would reappeal to the public to come forward with any information about this."
David's family have released the following statement in line with the anniversary of his death - and are asking anyone who has any information to help them find closure.
It said: "As the first anniversary of David’s death approaches, we would like to thank everyone involved with the investigation up to now.
"These last twelve months have been very difficult to deal with.
"David has missed so much, including what should have been his 50th birthday, instead of celebrating the day we marked the date by laying flowers in his memory.
"As a family we do not feel that we are able to grieve properly as every day we have to carry on with life knowing that someone who is responsible for such a savage and brutal murder is still to be identified.
"David was a very kind individual who did not deserve to have his life taken as he did.
"He was a dad, grandad, son, brother, uncle and friend and he deserves justice.
"We beg anyone with information to please get in touch no matter how small you may think it is."
