An Ellwood City man convicted of stalking Amish schoolchildren waived his detention hearing today on federal child pornography charges and will remain in custody at the Mercer County Jail on a federal detainer. 39-year-old Lucas Klobetanz was indicted last month after a search of his house by the FBI and state police turned up child pornography on a thumb drive and photos of young boys engaged in sex acts. Klobetanz was charged last winter with attempting to lure children into the courthouse of an Amish school. When the children told a neighbor, Klobetanz explained that he had dropped toilet paper and needed help picking it up. He pleaded guilty to stalking in that case and prosecutors dropped a related charge of luring.
