Nearly three years after their murder, a third man has been charged in connection with the deaths of Lisa Dudley and Guthrie McKay.

Sixty-four-year-old Bruce Main of Maple Ridge has been charged with first-degree murder. He made his first court appearance in Abbotsford Monday.

Police have not commented on the connection between the three accused and the victims.

Dudley was left bleeding and tied to a chair for four days after the first call to police from a rural Mission home on Sept. 22, 2008. She was discovered by a neighbour but died while she was being taken to hospital. McKay died at the scene from gunshot wounds.

The responding officer, Const. Mike White, was dispatched when authorities initially received a call of six shots fired, but he said he didn't see anything and didn't get out of his squad car to investigate.

White was later docked a single day's pay at an RCMP disciplinary hearing.

After the incident, RCMP policy was changed to require officers to speak directly to the person who makes a 911 call about shots being fired.

Earlier this year, police arrested and charged 52-year-old Jack Woodruff and 25-year-old Justin MacKinnon of Nova Scotia with two counts of first-degree murder.

Police say MacKinnon lived in four different provinces before his capture by police.

Neither victim had a criminal record or was known to police.
