Former pupils of a U.S. Catholic priest who molested up to 200 deaf schoolboys have spoken out about his offences after four decades of silence.
Father Lawrence Murphy preyed on students in the confessional, dormitories, cupboards and during field trips from the 1950s until 1974.
Pope Benedict XVI is accused of knowing about the allegations since the 1990s while - as Cardinal Josef Ratzinger - he ran an enforcement office in the Vatican.
In the Milwaukee case, Cardinal Ratzinger's office ordered that no trial take place, although the Archdiocese of Milwaukee has since paid out $28million to victims of abuse.
