Police launch fresh review into fatal fires in Fraserburgh

Derek Roy, 46, and Derek Youngson, 19, died on Hogmanay 2006

Police have launched a fresh review into two suspicious fires which claimed the lives of three men in Fraserburgh.

Derek Roy, 46, and Derek Youngson, 19, were killed in a blaze in Kirk Brae, in Fraserburgh, on Hogmanay 2006.

Police believe there is a link to the death of Gordon Graham, 43, in a fire at his home in High Street in 1998.

Officers are making a fresh appeal to identify two people seen in a car park near the old police office after the 2006 fire.

Det Supt Malcolm Stewart said: "Despite repeated appeals to the public, we have never been able to identify those two people.

"The man was wearing a black tammy hat and was with a female who had her trousers tucked into her knee-high boots.

"As we've said previously, and I want to emphasise it again today, these people are not considered suspects but may hold information which is of vital importance to the investigation and may not realise it."

Detailed review

Grampian Police launched a review of Mr Roy and Mr Youngson's deaths in October 2009, and it was extended to include the fire which claimed Mr Graham's life.

The findings were reported to the procurator fiscal in early 2010.

Det Supt Malcolm Stewart said officers would now re-examine the circumstances of both fires, carrying out a detailed review of the evidence and interviewing relevant witnesses again.

"We owe it to the families of the men who died to ensure that no stone is left unturned and, given that it is now three years since the last review was carried out, it is only right and proper that we take a fresh look at these cases," he said.

He said that both fires took place in suspicious circumstances.

"We believe that someone out there knows what happened," he added.

"Those who might have been reluctant to come forward in the past, for whatever reason, may be more willing to do so now.

"Families are still grieving for their loved ones and they deserve answers."
