“At the moment we are treating it as an unexplained death,” a spokesman said.
The Scottish Prison Service said it could not comment on the circumstances and confirmed a fatal accident inquiry would be held.
The court heard Mr Stephen was desperate for cash – having lost his job following a serious bike accident – when he targeted Grahame Murray at the cash point at Saltoun Square, Fraserburgh on September 30 last year.
He put 63-year-old Mr Murray in a choke hold and demanded that he “give me the money” before stabbing him in a “frenzied manner” with a kitchen knife.
Stephen ran, dumping the knife and his blood-soaked hoodie, after Mr Murray began shouting for help alerting people in a nearby pub.
Advocate depute Eric Robertson said a hooded Stephen mumbled “give me the money” before getting his victim in a “choke hold”.
Mr Murray was rushed to Aberdeen Royal Infirmary’s high dependency unit, suffering from a number of wounds and a partially collapsed lung.
The court heard doctors hope he will recover fully but at the time he remained at risk of a further collapsed lung or infection.
Mr Stephen, a former fish processor admitted attempting to murder and rob Mr Murray.
