Heriot-Watt lecturer Roger Gray was stabbed
A university lecturer found dead at his Edinburgh home was stabbed, police have confirmed.
Roger Gray, 64, was found dead in the hallway at his house in Merchiston Crescent at 0500 GMT on Saturday, following reports of a gas leak.
A Lothian and Borders Police spokesman said he had suffered injuries "consistent with stab wounds".
Mr Gray had worked as a statistics lecturer at Heriot-Watt University for 40 years.
He retired from full-time work at the end of September 2007 but continued to work for Heriot-Watt on a part-time basis.
The area around Mr Gray's home remains cordoned off and high-visibility patrols are being carried out to reassure neighbours.
A major incident team has been established at Leith Police Station, with a team of detectives working on the inquiry, supported by specialist officers.
Det Ch Insp Gareth Blair, who is leading the inquiry, said: "At the moment we are at an early stage in our inquiries, however we are following up a number of investigative opportunities.
"We are appealing for anyone who was in the area of Merchiston Crescent overnight from Friday night into Saturday morning, who saw or heard any suspicious activity, to contact police immediately.
"In particular, we want to speak to anyone who heard a disturbance from within the flat around 10pm on Friday night."
They also wanted to speak to Mr Gray's friends to build a full picture of his background.
Colleagues of Mr Gray previously paid tribute to him as "a much-valued" member of staff.
