A Grande Prairie court has handed a 10-year jail sentence to a man who pleaded guilty to a reduced charge of manslaughter in October of 2019.

Trevor Eldon Martineau was originally charged with murder after the February 16, 2019 death of 48-year-old Pierre Quesnel of Grande Prairie.

Quesnel’s family says he was the victim of a random attack.

Martineau was also given a lifetime firearms prohibition and ordered to submit a DNA sample in Grande Prairie Court of Queen’s Bench Friday.

He was given 1,122 days credit for time already spent in custody. The courthouse says the judge added 120 days credit because the court proceedings happening during the pandemic was considered a mitigating factor.

That leaves 2,408 days, or just over six-and-a-half years, left to serve.

Charges of assault causing bodily harm, theft under $5,000, and two more of breach of a probation order, were withdrawn.

Martineau was also given 18 months probation after a 2017 incident where a man tried to break into police vehicles with an axe. He pleaded guilty to charges of threats to cause bodily harm and breach of recognizance.

He was also charged after an August 2018 incident where a fire was started in an abandoned building. He pleaded guilty to a charge of mischief to property after originally being charged with arson. He was given 12 months probation in that case.
