A man who killed his girlfriend in a drunk-driving crash in 2010 has been sentenced to one year in jail followed by a three-year driving prohibition.

Trevor Livingston pleaded guilty to one count of impaired driving causing death in February. He was sentenced in B.C. Supreme Court in New Westminster Monday morning.

The crash happened in March 2010 as Livingston was driving Amanda Woodthorpe and two friends home after a night out at Roosters Country Cabaret in Pitt Meadows.

Livingston was driving a car owned by the Woodthorpe family when he made a sharp lane change on Lougheed Highway and crashed into a pole.

Other drivers estimated the car was traveling over 100 km/h at the time of the crash.

Woodthorpe was pronounced dead at the scene, while Livingston was put into a medically induced coma for several weeks after the crash and eventually had his right leg amputated. 

An expert statement submitted during the sentencing hearing said Livingston’s blood alcohol level indicates he was impaired at the time of the crash.

Keith Robinson said he has been in the courtroom every time his friend Livingston appeared before a judge.

"It's been very sad. I've been friends with both of them. I grew up with both of them," he said.

"I think the message is very obvious here. It's plain. It's a very obvious message: don't drink and drive."

Woodthorpe's mother has said she didn't want Livingston to go to jail, saying it was a sad case where nobody wins.
