Investigators say a grill was responsible for a Friday fire in Palmyra that forced two families from their homes. The fire broke out on Fayette Street at about six o'clock Friday night. The grill caused part of an addition to the house to catch fire. It took firefighters from Palmyra, Macedon, Port Gibson and Williamson an hour and a half to get the fire completely under control. There was damage to the addition and some smoke and water damage in the main part of the home. The Red Cross is helping the two families.
