The family of a solicitor who was stabbed to death in Durham have said that words cannot describe how they are feeling.
"Peter was a loving husband to Joanna, a devoted father to Lucy and Jessica and a much-loved son of George and brother to Helen.
"Words at this time cannot express how we, his family, are feeling. We would ask that anyone with information regarding what happened to Peter to please contact Durham constabulary.
"This is a very difficult time for us, his loving family, and we request that we be afforded privacy in order to try and come to terms with our very sad loss."
The body of Peter Thomas Maine, 56, from Wynyard, Stockton-on-Tees, was found near the running track of Maiden Castle Sports Centre.
He was under investigation for fraud by Durham Police.
A "murder-style inquiry" has been launched.
"We would especially like to hear from any rowers, dog walkers, cyclists and runners who use this area frequently.
"We are treating Mr Maine's death as suspicious. However, it does remain unexplained and we would appeal to the public for assistance."
