MERCER, Pa. (AP) — A father and son from Pennsylvania have been charged with molesting a girl who is unable to speak because she has cerebral palsy.

Online court records don’t list an attorney for 60-year-old Christopher Atkinson and 22-year-old Aaron Atkinson who live together in Mercer. That’s where the incidents allegedly occurred from January 2010 through November while the girl, who was as young as 13 during some of the abuse, was in their car.

State police say the girl recently moved to Texas where she reported the allegations to a family member. Police say the girl communicates using an iPad Touch. Child advocates in that state passed on the information to state police who filed charges Tuesday.

The Atkinsons’ home telephone is unlisted. They face a preliminary hearing May 20 on indecent assault and related charges.
