Sharon fire officials are investigating a blaze at a single-family two-story home on South Street. Fire Chief Bruce Vanderveen says the call, a little after 8:00 a-m , was a little complicated because some equipment and personnel were already in Clinton. He says the fire was out in under an hour with smoke and fire damage to the second floor, and smoke and water damage on the first. Seven people were displaced, and one was taken to the hospital. Vanderveen says the home did not have working smoke detectors.
