After finishing the newspaper, Dean drew five or six circles on the city map, with numbers like 1, 2, and 3 marked inside them. Each circle represented a crime, and the numbers indicated the order of their occurrence.
"The first incident happened in a remote city park where public facilities were old and surveillance was almost nonexistent. After the second incident, they all occurred in the urban area, spreading across all four directions—east, south, west, and north. The only area where nothing happened is here!" Dean picked up a pen and drew a large circle on a specific area of the map. The chances are high that the culprit lives in this area!
He turned to Carol. "Did you find any information about the person who sent the newspapers?"
