Farewell to the finest female to grace the "Dallas" stage, Mary Crosby (a.k.a "Kristin Shepard"). Her character was found dead in the Southfork pool by Cliff Barnes. On a much more sad note, this episode aired (5/1/81) five days after Jim Davis, the actor who played "Jock Ewing", died (4/26/81) from complications of surgery (perforated gastric ulcer).
