Eau Claire Fire Department personnel are trying to determine the cause of a Monday morning blaze that severely damaged a trailer at The Maples, a mobile home park at 1611 Western Ave. According to Deputy Chief Allyn Bertrang: Firefighters were called to a blaze at Lot 19 and found the trailer fully engulfed, but they were able to knock the fire down quickly and prevent it from spreading to nearby trailers. One person, believed to be the female occupant, was transported by ambulance to an area hospital after suffering burns. Her condition was unknown. Gary Puljas, one of the department’s fire inspectors, was on scene after the fire was extinguished to begin investigating its cause.
