I'm amazed you all missed a key clue pointed out in the beginning.
It was stated that the player uses the forgetfulness of the other players against them. As in, "oh yeah, last game we divied the loot up, and I got the +1 sword" when it really didn't happen. Effectively, this player is cheating.
It's one thing, in the game, to roll some dice, state your intent, and steal an item from a CHARACTER. It's another to lie about where the gear is, so you can trick a PLAYER out of their stuff.
I'd be very wary of that kind of gaming. That's not role-playing. Heck, it's meta-game cheating. It's also not very social.
As a DM, you can advise players not to play that way for the simple reason that it intrudes on other players' fun. You're not putting his idea of fun over everyone else's fun. It's not fair. You can also advise the players that you will condone any reasonable action the party takes against an anti-social character. Since the typical party has no qualms slaughtering tribes of orcs, why would they have a problem with killing a traitor in their midst? If that's not enough warning to players to get along or else...
Some simple things you can do is to try Gear cards. I'm making some templates right now for my campaign. Basically, every item you hand out, goes on a gear card and it goes to the guy who picked the item up. This makes it very obvious and very physical as to who has what. Unless the thief is actually stealing those cards (which is against the rules as CHEATING), he's not going to be short-memory-tricking anybody. It will also be obvious that Mister-Fat-Stacks is hoarding stuff.
In addition, you can change the method of exposing treasure in the game. Start having less loot on the bodies, and more loot given as payment/reward by benefactors. Meaning that LootBoy can steal 1gp rings off the bodies all he wants. When the party gets back to town, LordDeepPockets can hand-out +1 swords to anyone he feels like. And LootBoy can't stop that.
Just a few thoughts,
