Joe appeared in "The Great Game", and near the end was found to be West's murderer. He had been dealing drugs and owed money to some 'serious people'.
During West's stag night, a drunken Andrew had been talking about his job in MI6 and secret government plans, waving the memory stick around in front of Joe. Joe then stole the memory stick. The next time he saw Andrew, he accidentally pushed him down a flight of stairs, killing him. To rid himself of Andrew's body, Joe hauled West onto a train outside his flat, in the hopes that the train would carry the body away.
Joe wasn't mentioned after this scene, so it is unknown if he was arrested for taking the plans or not.
