Homes Wrecked, Dozen Hurt in Mississippi Tornado A tornado tore through Hattiesburg on Sunday as part of a wave of severe storms that downed trees, damaged buildings and injured more than a dozen people. The twister traveled down one of Hattiesburg's main streets and mangled homes, commercial buildings and structures on the campus of the University of Southern Mississippi. Emergency officials said at least 10 people were injured in surrounding Forrest County and three were hurt to the west in Marion County, but they weren't aware of any deaths. Mississippi Emergency Management Agency spokesman Greg Flynn said it appears that a single tornado caused the damage in those two counties and Lamar County. Hundreds of homes are damaged in Forrest County, along with a couple dozen in the other two. Gov. Phil Bryant declared a state of emergency. Flynn said the sheer scope of the damage was slowing their assessment. "The problem is, it was so strong that there's so much debris that there's a lot of areas they haven't been able to get to yet," he said. Forrest County Sheriff Billy McGee says 10 or 15 people were injured by the tornado that slammed Hattiesburg and other parts of the county - but none of the injuries was serious. He says, "Most of our injuries have been walking wounded." Bryant plans to go to Hattiesburg on Monday to check out damage in the city and at USM, his alma mater, spokesman Mick Bullock said. On Sunday night, John and Katherine Adams were cleaning up around their one-story white house where the storm punched holes in the roof, busted windows and completely destroyed the back porch. The couple was at home with their 7- and 3-year-old daughters when the tornado passed next to their house. All through the neighborhood, houses and vehicles were damaged by falling trees. "We're safe, and that's all that matters," said Katherine Adams, 46. John Adams, who's in the building supply business, said he was surprised to see broken boards that appeared to be from new construction in his yard because there are no homes being built nearby. "We've got stuff around here; I don't even know where it came from," he said. McConnaughey reported from New Orleans.
