Scott Hector, 20, died after being attacked at a flat in Aberdeen’s Marischal Court in April 2021.

Sean O’Halloran, 20, pleaded guilty to murder and Connor Adams, 18, admitted an amended charge of culpable homicide at a hearing last month at the High Court in Edinburgh.

The pair also admitted conspiring to rob the victim.

Mr O’Halloran, of Aberdeen, was sentenced to life in prison, with a punishment part of 11 years and eight months, and Mr Adams, also of Aberdeen, was jailed for seven years and three months.

At a hearing last month, the court was told that Mr O’Halloran stabbed Mr Hector on the body once with a knife and stole a small quantity of drugs from the flat.

Deborah Demick, deputy head national homicide team of the Crown Office and Procurator Fiscal Service (COPFS), said: “We have heard from Scott’s family the devastating impact his murder has had on them.

“Sean O’Halloran and Conor Adams carried out a violent, unprovoked attack on Scott.

“The consequences of this crime on this family have been enormous, through no fault of Scott’s and our thoughts are with them.”
