Shadow and I have worked together on this case for a couple weeks now. I am proud to announce that we have official apprehended Jack and he is behind bars. The main reason it took us so long to find him was because he was using Jack as an alias. His real name is Moe. During the interrogating processes we got a confession so the case is closed. Here is the recording of the interrogating and the confession. Also there are the mugshots.
