What's next for Mehmet Ali Agca?

Mehmet Ali Agca, the man who attempted to assassinate Pope John Paul II in 1981, was released from Ankara Sincan prison in Ankara, Turkey on 18 January 2010.
Mehmet Ali Agca served 19 years in an Italian prison for shooting John Paul, and another 10 years in Turkey for the earlier murder of a newspaper editor.
After the shooting, the Bulgarian Sergei Antonov, was arrested and held for more than three years in Italy. Eventually, he was acquitted over lack of evidence. At the time of the arrest Antonov was 32 and worked as a former manager in the Rome office of Balkan Air.
Shattered and physically damaged, he returned to Bulgaria unable to carry on a conversation or concentrate on complex tasks, symptoms his friends say came from the use of psychotropic drugs in his interrogation.
