The family of a pensioner murdered by a car thief who reversed over him after stealing the victim's Land Rover said they have been left "devastated".
James Simpson, 76, was crushed as his wife looked on after trying to stop the vehicle from being taken from his driveway in Ashgill, South Lanarkshire, last November.
Thief Christopher Grenfell, 25, claimed the pensioner fell under the car, but a jury at the High Court in Glasgow found him guilty of murder and judge Lord Burns jailed him for life, ordering him to serve a minimum of 17 years.
Mr Simpson's son James said following the verdict: "Christopher Grenfell decided to counter the actions of my father by committing the murder of a 76-year-old man when he had the clear option of simply driving away. In the wake of this choice, he not only left a man dying in the street, but also left his wife absolutely devastated."
Grenfell was also convicted of breaking into Mr Simpson's house to steal the car keys and, along with a second man, 24-year-old William MacVicar, was found guilty of car theft.
The pair stole Mr Simpson's 4x4 from outside his home on November 29.
His wife Minnie told the trial that her husband ran out to the car and opened the driver's door as he tried to stop the theft. The car pulled away, then stopped and reversed back over Mr Simpson, who suffered multiple rib fractures and collapsed lungs. His spine was also broken in two places.
"My mother was a happy, confident and independent woman. Now my mother is shattered, nervous and a lonely widow," her son said in a statement issued by prosecutors.
He paid tribute to his father as a man "filled with passion and compassion in equal measures".
John Dunn, procurator fiscal for the west of Scotland, said: "This is a tragic case involving the needless loss of life of a man who was simply trying to protect his property. A family has been robbed of a husband and father for no reason other than selfishness and greed."
