Two weeks after he suddenly tendered his resignation, a former Pennsylvania mayor has been arrested on a host of child sex offenses. Former Gettysburg Borough Mayor Chad-Alan Carr has been arrested by the Pennsylvania State Police on two felony counts of photograph/film/depict on computer sex acts involving a child and one misdemeanor count of corruption of minors. The charges stem from allegations dating back more than a decade, when the alleged victim was a high school student.
