Four child molestation victims so far sue ex-York swim coach, 3 businesses whose pools he used York Dispatch In April 1999, York-area swimming instructor Ronald D. Wolfe — who also worked for York County Children and Youth Services and volunteered in Scouting — pleaded guilty to molesting 20 children between the ages of 4 and 11, all of whom took swimming lessons from him. Sixteen of the 20 children were between the ages of 5 and 7. Four of the victims were girls, 16 were boys. Wolfe indecently touched them in his home pool and at three pools he rented time at between 1992 and 1997, often with the children's parents just feet away but entirely unaware, according to court documents.
