Two Hattiesburg families are homeless tonight, after their duplex in East Hattiesburg was destroyed by fire. A house at the intersection of Katie Avenue and Morton Avenue went up in flames around 8:30 p.m. Nearly two dozen Hattiesburg firemen fought the blaze for over an hour. About a half-dozen people were living in the home, which was divided into two apartments. None of the occupants were injured. Fire inspectors will investigate how and where the fire started.
