A 65-year-old man has pleaded guilty to two counts of second degree murder in connection with the 1995 deaths of a New Brunswick mother and her son.

Mary Lou Barnes, 37, and her 12-year-old son Larry William Mills Jr. were found dead in their British Settlement home near Sackville on November 6, 1995. Police say they were strangled.

Raymond Joseph White lived near the murder scene back in 1995, but he had no relationship with the victims.

Police say White was a suspect early in their investigation, but it took years to gather enough evidence to charge him.

White was charged with two counts of first-degree murder in connection with their deaths in April 2010. White was already serving time in a prison in British Columbia for a string a robberies he committed in Nova Scotia when he was charged.

White initially pleaded not guilty to the charges but police say the change of plea comes after a week of voir-dire testimony into the murders.

White is scheduled to appear in Moncton provincial court on November 1 for sentencing.
