LONDON, September 18 (CNA) - A priest has been dragged into the ongoing investigation into the disappearance of Madeleine McCann. Detectives are expected to put pressure on Fr. Jose Pacheco to break his vow of silence, which is paramount to the sacrament of confession.According to The Daily Mail, police are to question the priest to see if Kate McCann, 39, confessed to him she had killed her four-year-old daughter. But priests are bound by an oath never to reveal penitents’ confessions.
