They abused their foster children a lot such as spraying them with Dr. Pepper if they saw something that may or may not exist. They were ultimately brought down when Mysterion (a.k.a Kenny McCormick) serves them beer, which leads to not only physically harming each other, but distracting them so that a social worker enters the basement and sees the abused children. The Weatherheads, along with Eric Cartman (who had been in their custody), were arrested and featured on the show White Trash (a parody of both America's Most Wanted and COPS).
