BUFFALO, N.Y. (AP) - New York state officials say operator error was to blame for an amputee Iraq war veteran's deadly fall from an upstate roller coaster, and have cited the amusement park for having improperly trained workers.
Investigators cited Darien Lake Theme Park & Resort, located between Buffalo and Rochester, for not properly training the ride's operators on the safety and operations restrictions and said operators were unfamiliar with the coaster's safety requirements.
The ride has been closed since July 8, when James Hackemer, who lost both his legs to a roadside bomb in 2008, came out of his seat near the end of the ride and was thrown to his death.
Darien Lake didn't immediately respond to telephone and emailed requests for comment.
