Picower reportedly suffered from heart ailments and Parkinsons disease. Police are conducting a routing drowning investigation. Picower, a pal of Madoff, was under federal probe. U.S. prosecutors are trying to figure out if he knowingly profited from Madoffs $65-billion Ponzi scheme. Picower was named in a lawsuit to recover money for unwitting investors who were cheated.
