I checked the sending address (18JP8n2bzJhNXqiQvrS5h28mgEuGDaTn51) and found that there were only 78 BTC in that address at the time the transaction was broadcasted to the network. What might of happened was that the transaction was rejected by the Bitcoin network (or blockchain.info's bitcoind), but due to a bug the 80 BTC were still subtracted from beeteecee's online wallet.
