Detectives have told a coroner they still can't be sure whether Durham solicitor Peter Maine was murdered or took his own life.
The 56 year old was being probed over fraud allegations at the time of his death.
He was found stabbed in his running gear close to a Durham sports centre last year. Gregg Easteal reports.
