Lancaster business owner and former civic leader Chris Tillman has been arrested again, this time on sex-offense charges involving two young girls, both under age 15. According to an arrest warrant, one of the girls told the Lancaster County Sheriff’s Office in March that there had been repeated incidences over a two-year period in which Tillman sexually gratified himself by using her feet. The girl said this happened during teen sleepovers at Tillman’s house.
