Subject 1 was operating his boat on Lake Houston and pulling a tuber.  He stopped the boat in choppy waters to let the individual on the tube get back in the boat.  The individual tried to re-enter the boat from the transom, and with the choppy conditions and the number of people on board (5), the rear of the boat started sinking.  All occupants left the boat as it sank and were picked up by a passing boater and returned to shore.  The boat sank and is missing.
