Grande Prairie Man Arrested after Fatal Stabbing

Travis Fortnum


31-year-old Trevor Eldon Martineau has been arrested for second-degree murder, following a stabbing in Grande Prairie this weekend.

It happened on Saturday night in the area of 100 Avenue and 92nd Street.

Police were called around 5:00 P.M., when 48-year-old Pierre Quesnel was taken to hospital and Martineau was arrested.

Quesnel later died as a result of his injuries.


Martineau faces additional charges, in addition to the second-degree murder. These include:

  • Assault causing bodily harm
  • Theft under $5000
  • Breach of probation order (x2)

He remains in police custody, pending a bail hearing on March 11 at the Grande Prairie Provincial Court.

Quesnel’s daughter says her father was a husband, an uncle and a wonderful man who left his family too soon.
