DETECTIVES hunting a killer sought help from the victim's neighbours over the weekend.
The body of Colin Johnson, 40, was found by his girlfriend in his living room in Pickering Road, Pennywell, Sunderland, at 10.30pm on Saturday, January 17.
He had suffered multiple injuries.
Officers set up a mobile police station in the street and have made several appeals for witnesses to come forward.
On Saturday, investigators again interviewed residents in a bid to pick up further information into the apparently motiveless murder.
Detective Superintendent Ian Thornton, who is leading the investigation, said: "People may think the information they have is not important, but it could be crucial to this inquiry."
Anyone with information can visit the mobile police station or contact the incident room on 0191-563 6408.
* A man who was arrested and questioned by police over the killing was released without charge on Friday.
