Oxford professor's death was 'tragic accident', says wife Steve was the love of my life and we have known each other all of these years and he has never changed, even though he has achieved so much and has all these qualities. I will miss him more than anything else in the world. I do not believe that Steve's death is murder and I do not believe Devinder should be tarnished in this way. Police said today that a post-mortem examination had proved inconclusive and further tests would be carried out. Detective Superintendent Rob Mason, from Thames Valley Police's major crime unit, said Prof Rawlings's death "may be a matter for a coroner's inquest rather than a criminal court." Dr Sivia, has been released on police bail until April 18. Linda Davey, 64, Prof Rawling's older sister, said he was not the type of man to get into an argument over anything. She said: "They have been friends for 30 years. We can't think that there was any kind of fight. We can only assume that it was a terrible accident. Steven was big, but he was gentle.
