DETECTIVES investigating the death of a former solicitor say they are following up a number of lines of inquiry, thanks to calls fom the public.
Peter Maine, 56 was found on a footpath opposite the running track at Maiden Castle sports centre, on the outskirts of Durham city just after 8am last Sunday.
He was found with three stab wounds to his chest and was confirmed dead shortly after being taken to the University Hospital of North Durham.
Police are continuing to treat his death as suspicious and unexplained, but stress they are keeping an open mind as to how he received his injuries.
Mr Maine left a wife, Joanna, and two daughters in their early 20s, Lucy and Jessica. The family live in Wynyard village, near Stockton.
Police have established Peter and Joanna were out for a meal with friends in Yarm on Saturday night. The next morning Peter drove to Durham where at 7.25am he parked his car outside his former business office in Old Elvet, which has now been converted into student flats.
He carried some furniture into the premises before moving his car a short distance to a marked parking bay in the street, after which he set out on his run towards the riverside.
The officer leading the investigation, Det Chief Insp Steve Chapman said there had been a good response to the release of CCTV footage showing Mr Maine setting out on his run.
He said: “We are working on a number of lines of inquiry, which include building up a picture of Peter’s lifestyle, his friends and associates and his movements in the 24 hours leading up to his death.
Police have confirmed Mr Maine was arrested in April 2011 as part of a long-running investigation into allegations of mortgage fraud.
A second, larger-scale investigation has been conducted by Northumbria Police into similar alleged offences and seven people have been charged. Mr Maine was never arrested as part of the Northumbria Police investigation.
