A 21-year-old man has admitted killing a gay former lecturer.

Pawel Rodak admitted attacking 64-year-old Roger Gray at the latter’s home in Merchiston Crescent on March 18th and 19th this year.

He told the high court in Edinburgh yesterday that he stabbed the older man repeatedly.

Prosecutors rejected his plea of culpable homicide. Instead, he will be tried for murder.

Rodak denies a further charge of attempting to defeat the ends of justice. He is accused of turning on the gas in the flat and lighting a candle in a bid to destroy evidence.

He will face trial in December.

Mr Gray taught maths and statistics at Heriot-Watt University.

He was the third gay man to have been killed in the city in a 30-day period but police said the deaths were not related.
