A man has been sentenced to a minimum of 22 years in jail for the murder of a former Fettes College biology teacher in 2022.

Paul McNaughton admitted to luring 75-year-old Peter Coshan to a flat in Leith using a fake profile on a gay dating app before killing him.

McNaughton, along with his 65-year-old flatmate Paul Black, then concealed the body for days before dumping it in a layby in Northumberland.

The 29-year-old was sentenced to life imprisonment at Glasgow High Court on Monday.

Black, who was cleared of murder by a jury at Edinburgh High Court, was sentenced to a minimum of five and a half years in jail after being convicted of attempting to pervert the course of justice.

McNaughton first met the retired biology teacher online in 2021 and proceeded to steal tens of thousands of pounds from him after gaining access to his bank accounts.

When Mr Coshan found out about the thefts, he threatened to go to the police unless McNaughton provided him with free sexual favours.

McNaughton then hatched a plot to kill the retired teacher after becoming “fed up” with the situation.

Following the killing, which happened on either 11 or 12 August 2022, the pair hid the body until about 15 August, when they put it in a suitcase and drove it to a layby on the A696 between Otterburn and Belsay, dumping it next to a wall.
