THE family of an Inverkeithing man who died in Lochgelly from a stab wound have called for changes in the way that sudden deaths are dealt with in Scotland.

Colin Marr was found with a single stab wound in his home in July 2007.

His mum, Margaret, and step-father Stuart Graham have never accepted the official version that he committed suicide and previously highlighted the "repeated failures" of the authorities who they say have mishandled the case, and then lied to cover up their mistakes, from the very start.

Earlier this month, Stuart called for a change in the system when a sudden death occurs, highlighting flaws and shortcomings in current investigation processes.

Delivering a presentation titled 'Scotland’s Sudden Death Crisis: Unveiling the Truth' which was streamed live on Faces and Voices of Recovery UK charity's Facebook page, Stuart talked about "systemic failures" that have led to the current crisis.

"We need public reviews and focus on prevention of future cases with families at the heart of the reviews," he said. "It is sad when we get to around 1,200 deaths a year, we end up just saying this is the norm and we lose sight of the individuals and the families who have been impacted by this.

"This needs to change. I believe we are historically and systematically set up to fail."

Stuart said change was possible at "relatively low cost" by recognising the need of family involvement.

"We need a system that facilitates the potential to publicly review all sudden deaths with the aim to provide future cases with the families at the heart of the investigation and findings.

"With a system such as this, one of that is independent of COPFS, we should see far fewer cases than those like our families have faced."

Colin, a 23-year-old mortgage advisor and Dunfermline Athletic fanatic, was found dead on the living room floor of his home in Johnston Crescent, Lochgelly, on July 10, 2007.

Colin had a head injury, a single stab wound and a kitchen knife at his side.

His fiancee, Candice Bonar, has always insisted that he took his own life and a fatal accident inquiry in 2011 proved inconclusive.

When confirming the review last year, a spokesperson for the Crown Office and Procurator Fiscal Service said: “We appreciate the importance of this work to the family and they will be informed of significant developments.

“Once further enquiries are complete, all the evidence will be reviewed by a prosecutor who has had no previous involvement in the case.”
