Summary:  The OIC reports that at 5:50 p.m., Dale stopped at the park to urinate, discovered the body, drove 3 miles and reported the death to two park workers.  Eight months later, a New York daily newspaper reported that two park workers admitted that they had discovered the body, whereupon Dale decided to come forward, contacted G. Gordon Liddy, and the FBI interviewed Dale.  Based on a "detailed" comparison of Dale's version of the conversation with the park maintenance workers', Fiske gave credence to Dale's account, yet these accounts differ in virtually every detail, including that the maintenance workers reported that Dale said the body had been shot.  Dale saw no gun and believed death had been caused by a blow to the head.
