On June 14, 1969, six-year-old Dennis Lloyd Martin walked into the rugged forest terrain of the Great Smoky Mountains National Park and never returned. His disappearance began the most extensive search and rescue attempt in the history of the National Park Service. The F.B.I. reported to the public that Dennis Lloyd Martin was nothing more than a lost child for over fifty-four- years; however, they refused to release the files to the public. During my research, it became clear the information being released to the public by the F.B.I. was intentionally misleading to conceal the true nature of their investigation. In two years, the author filed nineteen Freedom of Information Act applications requesting the F.B.I.’s file on Dennis Lloyd Martin's disappearance, all of which were denied based on the Exclusionary Rule. Over the years, I had filed nineteen Freedom of Information Act applications requesting the F.B.I.’s file on Dennis Lloyd Martin's disappearance, all of which were denied based on the Exclusionary Rule. In November 2021, the author petitioned the Department of Justice for the records, challenging the use of the Exclusionary Rule. After a long and problematic endeavor, the Dennis Lloyd Martin file was released to the public on June 22, 2022.
