The Dauphin fire department and RCMP re investigating 2 house fires in 2 days. An early Sunday morning blaze damaged the rear of a vacant house, and was quickly put out. Then last night, there was another house fire that destroyed one home and damaged another. All the residents escaped injury, and crews were on scene for more than 4 hours. Both fires have been deemed suspicious in nature, but it’s not known if they’re connected.
