Nashville Bombing Left 12 Buildings Collapsed or 'Unsafe', Engineers Say On 1/10/21 at 6:06 AM EST Engineers have identified 12 buildings that have collapsed or are considered unsafe, including several that require demolition, in downtown Nashville after the Christmas Day bombing. Officials have identified Anthony Quinn Warner as the man responsible for the explosion that injured three people and damaged dozens of downtown buildings early on December 25. But they have not provided information on what may have driven Warner to blow up his RV outside the AT&T transmission building, although they are reportedly investigating whether he believed in conspiracy theories involving aliens and 5G cellphone technology.
