DARIEN, N.Y. (AP) — A U.S. Army veteran who lost both legs in Iraq and had been trying to rebuild his life was killed after he was thrown from a roller coaster at an upstate New York amusement park. Teams of inspectors on Saturday were examining the Ride of Steel coaster at the Darien Lake Theme Park Resort, about 30 miles east of Buffalo. Sgt. James Thomas Hackemer, 29, was ejected from the 208-foot-tall ride early Friday evening after climbing aboard during a family outing.
