The Hitman has been found!

Yesterday, the bike rolls into a shop. The mechanic who is working on it recognizes, and makes a few phone calls. Viola! The serial number is confirmed by Joe and immediately heads down to the shop with a few friends and the cops.
Please contact Brooklyn Machine Works if you have any information leading to the retrieval of these bikes.
718-387-3307. Thank you.
