A 2nd victim I never heard about

How can people just disappear like this unless it’s a professional job?

The release of the Turk who shot Pope John Paul II may shed light on a quarter-century-old mystery: the disappearance of the teenage daughter of a Vatican employee whose kidnappers say was abducted to win the gunman's freedom.

Orlandi, the daughter of a Vatican messenger, disappeared after a music lesson in Rome on June 22, 1983. She was 15 at the time. Her self-proclaimed kidnappers demanded Agca's release for her freedom, although they never offered any proof they had the girl or that she was alive.
