Allan Simpson Wood, 39, was driving at nearly twice the speed limit when he crashed head-on into Bryan McCron's car on Colebrook Road in Surrey in July 2010, killing McCron and injuring his 17-year-old son Connor.

In addition to the two-year sentence, Wood was given three months for punching Connor at the scene as he tried to call 911 to save his dying father.
Bryan McCron's sister, Vicki Macri, says the family is satisfied, even though her brother can never be brought back.
"We feel vindicated for Bryan that [Wood] is going away for two years," said Macri.
"He has a five-year driving ban. It will never be enough, but for us, we decided as a family that we didn't have control over what he was going to get, so we were going to accept it and maybe people out there will learn a lesson."
The judge noted Wood's "less than impressive" driving record which includes an impaired conviction in 2002.
Wood pleaded guilty to the two charges last month. Additional charges of driving while impaired and refusing to give a breath sample were stayed.
