Seven people were injured Thursday when heavy rains caused a partial roof collapse at a Barbourville, Kentucky, business, officials said. Initial reports from the scene were that the drainage system at Tru-Seal Manufacturing was clogged and caused water to pool on the roof, causing a partial collapse, said Kentucky Emergency Management spokesman Buddy Rogers. Three people were taken to a hospital with non-life-threatening injuries, Rogers said. Several others walked over to the hospital on their own with minor injuries, he said.
