The man who tried to kill Pope John Paul II, Mehmet Ali Agca, is surrounded by journalists in Ankara January 18, 2010. Agca, who tried to kill Pope John Paul II nearly 30 years ago was released from a Turkish prison on Monday, rekindling the mystery over whether he acted alone or had been hired by a Soviet-era secret service. He served 19 years in an Italian prison for the attack, before being pardoned on the pope's initiative in 2000, but was extradited to serve a sentence in his home country for other crimes including the 1979 murder of a newspaper editor.
