Detectives investigating the death of a 40-year-old man in Cheshire believe he may have been murdered for cash he kept in his flat.
The body of Carl Chadwick was discovered in Grasmere Avenue, Warrington, on 29 January. He had been stabbed and strangled.
Police believe thousands of pounds were stolen from his flat after his death.
A 32-year-old man and a woman, 29, were arrested on suspicion of murder and have been bailed until 8 March.
Mr Chadwick, known locally as Dancing Carl, was described as vulnerable by his family.
He was known to keep cash in his flat, police said.
Officers have released CCTV footage of him in a local shop 11 days before his body was found, hoping it will jog someone's memory.
Det Insp Nigel Wenham, of Cheshire Police, said: "This CCTV is the last confirmed sighting I have of Carl and I believe he may have died within a couple of days of it being taken.
"I am keen to speak to anyone that saw or spoke to Carl around this time as you could have vital information for my investigation."
He said he was trying to build up a picture of what had happened to Mr Chadwick since the CCTV recording.
He added: "I am convinced that the answers I am seeking lie in the community.
"I would urge people to ask themselves if they have noticed anyone behaving differently lately, or if someone suddenly appears to have more money and their spending habits have recently changed?
"Your information could be crucial to finding out who was responsible."
