I am sorry, I am not buying that he is stealing from you guys. He is in the Army Reserves. There is like, a 99.9% chance that if he falls off the face of the communications world, he was called upon. Sean had a 100% good reputation, then stopped talking all together. He didn't PM you looking to work something out, he didn't continue to take your money in an attempt to rob Peter to pay Paul.
On Sean's behalf, I am asking you guys to chill out. It sucks that he left with open transactions, but I doubt he could do a damn thing about it.
