(FYI, Agca converted to Catholicism after Pope John Paul II visited him and prayed with him.)
"His desire to be near his people nearly killed him - on 13th May 1981 he was shot by Mehmet Ali Agca in Saint Peter's Square, Rome. He believed that he survived, because it was on the day of the apparition of our Lady of Fatima, and for this reason he traveled to Portugal at the first opportunity the following year to place one of the bullets in the crown on the head of the statue of the Virgin Mary in Fatima, Portugal. Later he visited Agca in prison and forgave him. Agca converted to Catholicism."
