Three teenagers have been found guilty of stabbing a grandfather to death during a robbery at his bungalow in Bedfordshire.
The boys, their faces hidden by hoodie, had gone to the home of Sharif Demirsay, 65, in Vineyard Way in Kempston in May 2013 to steal Asian gold. After Mr Demirsay opened his door to the gang, there was a violent confrontation in his hallway.
He was stabbed 11 times and died from a fatal wound to his heart.
Courtney Glynn, who was 18 at the time, along with Muhammed Rashed, who was 17, and Hameedur Rahman, who was 15, were all convicted of murder at Luton Crown Court.
A fourth man, Travis Dixon Charles, was cleared of all charges.
In a statement, the family of Mr Demirsay said: "The past 11 months have been an horrific ordeal for us all. This incident has had a devastating effect on so many lives. This was an unprovoked attack on an elderly couple who should have been safe in their own home."
The police officer who led the murder investigation, Detective Inspector Tim Redfearn, said it was hard to make any sense of the crime.
He said: "Parshini and Sharif were two kind, much-loved, family-orientated people living quiet lives in a modest home. Parshini showed the utmost bravery; even as her partner was stabbed in front of her, she tried to fight off the robbers with the first thing that came to hand."

"The needless level of violence used and the ferocity and merciless nature of it for so little gain beggars belief, even for an experienced murder detective. The killers didn’t give either one of the old couple a chance to hand over what money they did have before launching into this appalling attack."
