A feed plant in Omaha collapsed Monday, sending nine people to area hospitals and leaving some of those inside the facility unaccounted for, officials said. Omaha Interim Fire Chief Bernie Kanger said "some employees are still unaccounted for" and the International Nutrition facility sustained significant structural damage from the collapse, WOWT-TV, Omaha, said. Officials contacted Nebraska's Urban Search and Rescue Team in Lincoln for assistance, the television station said. On its twitter page, the Omaha Police Department posted notification of the collapse and pictures. One of the posts read: "Smoke getting heavier. Please stay back. Large #OFD presence in the area. #OPD restricting access." One firefighter was injured, but Kanger said the firefighter's injuries weren't considered life threatening. Kari Cook told WOWT her fiance, John Broderick, a supervisor who was on the building's second floor, texted her: "Major accident. I'm hurt and trapped. I love you."
