The review will aim to improve the efficiency and effectiveness of investigations into deaths in prison and ensure those affected are treated in a trauma-informed way.

The review which was commissioned by Justice Secretary Angela Constance, in consultation with Lord Advocate Dorothy Bain KC, will also identify barriers that families face in engaging with the FAI process and address the time it takes for them to be completed.

An advisory group, recommended by the chair and appointed by Ms Constance, will support Sheriff Principal Abercrombie. Its membership is expected to be agreed and announced within weeks.

Ms Constance said: “A review of the FAI system was a key action from the Government’s consideration of the FAI inquiry determinations into the tragic deaths of Katie Allan and William Lindsay.

“Families have been let down and their experience of the system has added to their grief. Their voices will be heard and listened to during this independent review. The remit of the review will consider issues surrounding FAIs held into deaths in prison custody.

“Maintaining the pace of reform is essential, which is why I have asked to receive the report by the end of this year.”

Sheriff Principal Abercrombie said: “I am pleased to be leading this review. I understand that concerns have been raised about how the FAI system currently operates in relation to deaths in prison custody.

“As an independent chair, ably assisted by my advisory group, I am looking forward to hearing from all those with experience or knowledge of the system.”
