"He did voluntarily submit to a polygraph exam," Snyder said. "Nothing in Mr. Williams's lengthy interview -- and it was a long, detailed interview -- nor his polygraph exam indicated that he was involved or had any additional information about Tricia Todd's disappearance."
"This investigation continues, and additional information will be made available as we have it," said Snyder. "As of now, there are no suspects -- nobody that we can link to Tricia Todd's disappearance."
