Matthew DuPlessis is sentenced to nine years and three months in prison after admitting causing death by careless driving while unfit through drugs and perverting the course of justice. The case centers on his account of events involving his girlfriend.

According to reporting, DuPlessis falsely claims his girlfriend was the victim of a hit-and-run. He later pleads to offences that include the drug-impaired driving element, as well as actions intended to mislead investigators. The sentencing reflects both the fatal driving charge and the separate charge relating to obstructing or interfering with the course of justice.

The two provided sources present the same core facts and sentencing outcome, with no differing angles beyond repetition of the length of the sentence and the stated admissions.
