A former beauty queen in western Nebraska is suing Scotts Bluff County officials over injuries she suffered when a bull charged her at the 2010 county fair.

Jessica Littlejohn and her father William Littlejohn filed the lawsuit this week against the county and all the groups involved with the fair.

The accident happened when a bull broke loose while Littlejohn and six other girls, including former Miss America Teresa Scanlan, were being introduced.

Littlejohn says she suffered a brain injury when she was struck by the bull and thrown into the air. At the time, fair officials said she suffered only a mild concussion.

County officials have denied responsibility for the accident but haven't formally responded to the lawsuit.
