The High Court in Edinburgh previously heard that Colville, from Stirling, crashed the car after driving around a bend at more than 85mph.
Speaking from his home in Brecon, in Powys in mid-Wales, Kevin Page said he also blames Colville for the loss of his wife “because of the loss of her son.”
He said: “What she’s done to us has destroyed us.
“I can guarantee if my son was still with us, Jill would still be with us.
“Life is hell now, you wake up in the night, you can hear a pin drop.
“You get up in the morning, the house is empty.
“You see Connor’s bed where he left it, nobody has ever slept in it since.”
