Murderer of Edinburgh teacher sentenced to life in prison

The punitive portion of the sentence is 22 years and will be backdated to August 18, 2022. McNaughton, 29, pleaded guilty to both charges at an August 2023 hearing.

His co-accused, Paul Black, 65, was sentenced to five years and six months in prison for attempting to defeat the ends of justice.

Moira Orr, head of homicide and major crime at the Crown Office, said: “This is a cruel and brutal murder of an elderly man who was quietly enjoying his retirement. Peter was loved by his family and friends in the local community. He has had a positive impact on the lives of many people.

“But his own life was cut short by the despicable actions of Paul McNaughton. He showed cavalier disregard for his actions and will now serve a life sentence for his crimes.

“As prosecutors, we have worked hard to bring justice to Peter and his family. The COPFS team used every tool at their disposal to ensure that these two men faced the consequences of their horrific crimes. Our hearts go out to Peter's friends and family who have patiently waited for justice as they come to terms with today's outcome.
