Steven Williams and Tricia Todd<\/figcaption><\/figure>\n

Steven Williams, a 30-year-old U.S. Air Force staff sergeant stationed at Seymour Johnson Air Force Base in North Carolina, has confessed<\/a> to killing his ex-wife, Tricia Todd, on the night of 26 April 2016. Williams reportedly<\/a> dismembered Todd with a chain saw and buried her body parts in an acid-filled container in a pre-dug grave in a Florida nature preserve.<\/p>\n

Despite having committed a premeditated murder, on or about 3 May 2016, Williams passed a polygraph “test” about his ex-wife’s disappearance. As Huffington Post<\/em> senior crime reporter David Lohr noted<\/a> on 5 May:<\/p>\n

A search of Williams\u2019 car showed nothing unusual, authorities said, and he passed a polygraph examination.<\/p>\n

\u201cHe did voluntarily submit to a polygraph exam,\u201d [Martin County, Florida Sheriff William] Snyder said. \u201cNothing in Mr. Williams\u2019s lengthy interview \u2014 and it was a long, detailed interview \u2014 nor his polygraph exam indicated that he was involved or had any additional information about Tricia Todd\u2019s disappearance.\u201d<\/p>\n

Snyder added that \u201cat this point, there is no focus that needs to be on the former husband.\u201d<\/p><\/blockquote>\n

It would appear that Williams’ passing the polygraph helped to misdirect investigators, at least temporarily. Williams ultimately confessed to killing Todd and agreed to lead investigators to her remains as part of a plea arrangement which will see him incarcerated for 35 years.<\/p>\n

Steven Williams’ fooling the polygraph after committing such a monstrous act calls to mind the case of “Woodchipper Killer” Richard Crafts, who passed a polygraph “test”<\/a> despite having killed his wife, Helle Crafts, dismembered her body with a chainsaw, and ground up the parts with a commercial woodchipper.<\/p>\n

It would be a mistake to rationalize away these failures of the polygraph to detect deception by saying, “well of course they passed, they were psychopaths who felt no remorse for their actions.” The fact of the matter is that there is little evidence regarding whether psychopaths have any special advantage when it comes to beating polygraph “tests.” The important thing to understand is that polygraphy has no scientific basis<\/a> whatsoever.<\/strong><\/p>\n

Polygraph methods were devised by interrogators who had little understanding of the scientific method1<\/a><\/sup>, and anyone can fool the polygraph<\/strong> using simple countermeasures that polygraph operators cannot detect<\/a>.<\/strong> Polygraph countermeasure techniques are documented in Chapter 4 of AntiPolygraph.org’s free book, The Lie Behind the Lie Detector<\/em><\/a> (PDF).<\/p>\n

 <\/p>\n<\/div>\n

  1. Cleve Backster, who started the CIA’s polygraph program and devised a polygraph technique called the Zone Comparison Test that was likely used in Steven Williams’s polygraph interrogation, was convinced, based on his examination of polygraph charts, that plants can read human thoughts<\/a>. Real scientists have been unsuccessful in replicating his results<\/a>. [↩<\/a>]<\/span><\/li><\/ol>","protected":false},"excerpt":{"rendered":"
