A central Alberta woman has been sentenced to a year in jail for a hit and run that killed a teenage longboarder.

Jessica Masyk, who is 26, had pleaded guilty in August to failing to stay at the scene of a collision, public mischief and driving while unauthorized.

Trystan Sorenson was 18 when he was killed while longboarding near Penhold in May 2014.

He was hit by an SUV that was later found burned out in a field.

Two men were convicted of torching it.

In handing down the sentence, Judge John Holmes in Red Deer court called Masyk's actions "callous in the extreme."

Masyk also faces a two-year driving ban when she is released.

Longer sentence

The sentence is more than the six to eight months the Crown and defence had been seeking.

After her son died, Sorenson's mother circulated a petition seeking increased punishment for hit and runs that result in major injury or death. She also called for defined mandatory penalties for all hit-and-run collisions.

Sorensen said at the time that she didn't feel Masyk was being held responsible for killing Trystan because none of the three charges dealt specifically with his death.

"We spend our lives as parents teaching our children that you have to take responsibility and culpability when you do something wrong ... (but) when you get into the (justice) system, it reverses it," she said in August.
