BATAVIA, NY — A double-amputee Iraq war veteran who was hurled off a towering roller coaster to his death never should have been allowed on the ride, but park operators will face no criminal charges despite violating park policy, authorities said yesterday.

Signs at the Ride of Steel roller coaster at Darien Lake Theme Park & Resort clearly state riders “must have two legs,” said Genesee County Sheriff Gary Maha, whose office found no recklessness, intent or other criminal wrongdoing.
