It was a busy weekend for Utica firefighters, who battled three fires, two that happened within 15 minutes of each other. Firefighters were called to 201 Higby Road just before 11:00 Saturday night for a house fire. The fire started when a large tree limb fell onto an electrical line, causing an electrical malfunction in the dishwasher in the kitchen. Then just after 11:00, firefighters responded to the State Office Building on Genesee Street. Chief Fire Marshal Raymond Beck says the fire started in a computer room of the State Department of Labor's Regional Office and One Stop Career Center on the first-floor of the building. The fire destroyed the contents of the room and smoke and water damage was reported throughout the second-floor. It took firefighters from Utica, New Hartford, Maynard and New York Mills several hours to bring the blaze under control. The cause of the fire remains under investigation.
