A Chattaroy couple were killed following a mobile home explosion and fire on Wednesday evening.
Investigators continue to center their investigation on the fire being deliberately set as part of a domestic dispute.
Mike Asselin, 51, who passed away on Friday, and his wife, Sheila, had been separated for the past couple of months. Investigators have not ruled out the possibility that Asselin had disconnected one of the mobile home gas tanks and then set a match to the escaping gas.
