Priest attack

Going out from the castle square through the same gate as he entered M ran into a priest who started to talk with M about ”right and wrong”. M was really irritated about this and simply hit the priest on the cheek. The priest was so badly hit and ended up in hospital. This is known as ”The Priest Attack in Gamla stan”. To memorize or lets say pay back that this happened to the church the city decided to put up a statue of the priest Olaus Petri here. By coincidence, the life time of Olaus Petri seen on the label on the statue is exactly the same as the age of the man who was murdered. 

Title of the document HOW OLD WAS THE MURDERED PERSON? ( write like this: "age??" )
