please make all the information about chen jianhai public as soon as all the money is out of his hands. Especially any personal information such as home address or business addresses. Also all your correspondances with him, especially emails where he incriminates himself. Any chance you recorded any of your conversations with him? If not make sure you do it from now on, and make sure you get a recorded "confession" (if needed try to trick him to go through exactly how he stole the money).
