The grandmother of an 11-year-old boy from Tennessee who was injured on a roller coaster in Missouri says doctors are concerned they might not be able to save his legs. Shelandra Ford is with Aalondo Perry at a Missouri hospital. He was hurt in Branson on Sunday. Ford told WREG-TV in Memphis, Tennessee, that her grandson is visually impaired. She says he fell when he tried to get off The Branson Coaster and was trapped under the ride’s rails for 1 1/2 hours. Ford says her grandson’s legs and one arm were crushed. The Missouri Division of Fire Safety is investigating.
