DETECTIVES investigating the death and mutilation of a man in Chester say they can now place his whereabouts on the afternoon before his death.
However, they have still not found the weapon, believed to be a sharp-bladed knife.
Stephen Charles Prudhoe, 49, was found dead at his home earlier this month.
Tests have now been completed on Mr Prudhoe's dog, Milo, a small cross-breed found wandering round the property at Blacon Point Road to see if he had eaten the missing body parts.
A police spokesman said: "Cheshire Police has now received forensic results and there is no evidence from these that links the dog in any way to the body, or to indicate that the dog has digested any human body parts."
DCI Andy Marsden, leading the investigation, said: "We have ruled out any involvement from the dog, and we hope this will help focus the investigation."
Mr Prudhoe was found at 5.10pm on Wednesday March 10.
He was known for walking his dog up to five times a day around the local area, including the Spar shop where he bought alcohol each day.
Officers say he was a heavy drinker and had recently been known to smoke small amounts of cannabis.
Stephen Prudhoe was found on the upstairs landing of his home, fully clothed in a T-shirt, shirt, trousers and socks.
He was last seen alive by a friend at his home at around 11.30am on the day before his death.
DCI Marsden said a post mortem had revealed the mutilation took place after Mr Prudhoe died, and that pneumonia and a heart attack had contributed to his death.
Officers are keeping an open mind about how it happened and discussions are still under way with Cheshire's coroner Nicholas Rheinberg over the possibility of a second post mortem.
Further forensic tests are being carried out at Mr Prudhoe's home, and anyone with information is asked to contact the detectives on 01244 613087, or call Crimestoppers anonymously on 0800 555111.
