An electrical malfunction appears to have been the cause of one of two serious fires the Wilton Fire Department responded to last week.A home at 42 Scribner Hill Road was heavily damaged by fire on Wednesday, March 16. Two days later, on March 18, a contractor\u2019s truck containing landscaping equipment parked at 26 Clover Drive was \u201ccompletely destroyed\u201d by fire.Firefighters responded to an automatic fire alarm at the Scribner Hill home around 4 p.m. and requested mutual aid from Weston, Westport, Ridgefield, New Canaan and Georgetown.Weston covered Wilton fire headquarters, and the other agencies responded to the scene. By 4:30, firefighters had knocked down the blaze, which had been in the \u201cback corner of the home,\u201d according to Deputy Fire Chief Mark Amatrudo.\u201cWhen we got here, there was smoke coming out from throughout the house, and the house was locked. No one was home,\u201d Amatrudo said.FIrefighters forced entry into the home through the front door, \u201clocated the fire, and within half an hour the firefighters had the fire completely under control,\u201d he said.\u201cNo one\u2019s been injured; there was no one home at the time of the call,\u201d he added.New Canaan Fire Marshal Fred Baker, who investigated the fire, described the fire as accidental. \u201cThe cause appears to have been an electrical malfunction in the master bedroom,\u201d he said.The call for the truck fire coincidentally also came in around 4 p.m. last Friday. When Engines 1 and 2 arrived at the scene minutes later, the landscaping truck, which belonged to Norwalk landscaping, masonry and design contractor DeMilo Bros., was completely engulfed with flames.The blaze was knocked down before 4:30. \u201cNobody got hurt,\u201d Fire Chief Ronald Kanterman said, but the truck was \u201ccompletely destroyed.\u201d\u201cWe have nothing at this point\u201d on the cause of the truck fire, Westport Fire Marshal Edward Zygmant told The Bulletin on Monday, March 21.
