He looked though the files of the crime scenes, trying to understand the pattern of the victims. It didn't take him too long to find it and judging by that, he already had an idea on who the killer was and was to 99,99% sure. So he drove out to a small house somewhere at the other end of the city.

After arriving there, he approached the door and rang the doorbell.

Some moments later, the door opened and Will took out his FBI badge.

"FBI. You're under arrest for the murder of 7 people."
