A fast moving storm caused damage throughout Middle Tennessee, including injuries to a 12-year-old boy who was reportedly hurt when a large tree fell through a mobile home on Riley Road in Clarksville.

The large tree crashed through the trailer destroying the structure and furniture inside as mud and rain filled the home. The boy, Francisco Rojas, was taken to the hospital with injuries to his back and legs, according to his brother Adrian Rojas. His mother, Elizabeth Rojas, said later the boy's fingers were broken.
