Disappearance of Emanuela Orlandi

Emanuela Orlandi (born 14 January 1968) was a Vatican teenager who mysteriously disappeared while returning home from music school in Rome on 22 June 1983. The case received worldwide attention due to the public appeal of Pope John Paul II for her release after an unnamed terrorist organisation claimed to be holding the girl in exchange for the liberation of Mehmet Ali Ağca, the Turkish terrorist who had attempted to assassinate the Pope two years prior.
