CASPER, Wyo. (AP) — Police in Wyoming say a criminal investigation into a retired Roman Catholic bishop accused of childhood sexual abuse by more than a dozen men remains open. The Casper Star-Tribune reports a victim advocate from the Natrona County district attorney’s office had told an alleged victim that retired Bishop Joseph Hart would not be charged. District Attorney Dan Itzen told Cheyenne police that he is still pursuing charges. A police spokesman said Itzen had a misunderstanding over a document. Neither prosecutors nor an attorney for Hart returned messages Monday seeking comment.
