Did a child get decapitated on the v2 in six flags theme park in Gurnee IL?
There is no official report or press statement from the theme park about the accident on the V2. You can get additional information regarding the V2 ride by visiting the parks official website at http://www.sixflags.com/greatAmerica/index.aspx.
I can assure you, that even if one did, the theme park in question would greatly appreciate us NOT talking about such a thing. (Bad PR)
