A B.C. man has pleaded guilty to the second-degree murder of his mother.

A news release from the Integrated Homicide Investigation Team says Donovan Penner entered the plea in B.C. Supreme Court on Monday, less than a week after his trial began.

Penner was 47-years-old when he was arrested at the scene of the October 2014 murder of Sunshine Coast resident Denise "Esme" Lachance.

Police have not said how the 67-year-old woman died or what motivated her slaying.

Penner's sentencing has been set for Feb. 26.
