Greek authorities know that the shooter arrived at Athens International Airport. They are now trying to find out whether he visited any other cities in Greece.

Greek authorities believe that the killer could have traveled to Greek cities by bus. Tarrant was known to have made a long trip across the Balkans by bus.

The broadcaster notes that one word on the shooter’s rifle, in particular, attracted the attention of authorities — Lepanto, the name of the modern city of Nafpaktos, where the famous naval Battle of Lepanto took place in 1571.

In the battle, a fleet of the Holy League, led by the Venetian Republic and the Spanish Empire, inflicted a major defeat on the fleet of the Ottoman Empire.
