Both men died while in legal custody at HMP Barlinnie during December 2020.
An FAI is mandatory under Section 2(4)(a) of the Inquiries into the Fatal Accidents and Sudden Deaths etc. (Scotland) Act 2016.
A preliminary hearing will be held on 2 October 2025 at Glasgow Sheriff Court.
The purpose of a Fatal Accident Inquiry (FAI) includes determining the cause of death; the circumstances in which the deaths occurred, and to establish what, if any, reasonable precautions could have been taken, and could be implemented in the future, to minimise the risk of future deaths in similar circumstances.
Unlike criminal proceedings, FAIs are inquisitorial in nature, and are used to establish facts rather than to apportion blame.
This Inquiry will explore the circumstances of both deaths, with an anticipated focus on SPS’s policies and procedures around drugs and the support provided to Mr McKinsley and Mr Watson by SPS and the NHS.
Procurator Fiscal Andy Shanks, who leads on fatalities investigations for COPFS said:
“The Lord Advocate considers that the deaths of Lee McKinsley and Barry Watson occurred while in custody and as such Fatal Accident Inquiry are mandatory. The lodging of the First Notice enables FAI proceedings to commence under the direction of the Sheriff.
“An FAI will allow a full public airing of all the evidence at which families and other interested parties can be represented. The evidence will be tested in a public setting and be the subject of judicial determination.
“The families will continue to be kept informed of significant developments as court proceedings progress.”
