MADISON, Wis. (AP) – A Wisconsin appeals court has ruled in favor of a Milwaukee high school bus driver who argued a lower court failed to consider some evidence and unfairly used testimony in convicting him of sexually assaulting a student.   The 1st District Court of Appeals on Wednesday ruled a Milwaukee County Circuit Court lacked sufficient grounds to convict 26-year-old Gene Echols of second-degree sexual assault and sexual assault of a child by a person who works with children.  A high school student accused the bus driver of sexually assaulted her in 2010 after the two got into an argument. Echols argued the lower court ignored evidence that the student had a long history of disciplinary problems at school. Echols also said the court unfairly used testimony from the school bus safety director who Echols said had a history of lying.
