Would you still agree to take a test after reading this?
Innocent people frequently fail polygraph tests due to anxiety, fear, or stress, leading to false positives. Notable cases include Frank Sterling (wrongfully imprisoned for 22 years), Bill Wegerle (suspected in his wife's murder), and John Sosnovske (who was wrongly pressured to plead no contest). These cases underscore that polygraphs are not infallible.
Frank Sterling (1988): After failing a polygraph regarding the murder of Viola Manville, Sterling was coerced into a false confession and served 22 years in prison. The actual killer, Mark Christie, had passed a polygraph for the same murder and went on to kill another victim before his guilt was discovered.
Bill Wegerle (1986): Suspected of killing his wife, Wegerle failed a polygraph test. He was innocent; it was later proven that the BTK killer, Dennis Rader, committed the crime.
John Sosnovske (1991): Protesting his innocence in the murder of Taunja Bennett, Sosnovske failed a polygraph, while his co-accused (who was actually involved) passed, leading to a false conviction.
Byron Halsey: In a case highlighted by the American Polygraph Association, Halsey failed a polygraph and was wrongfully convicted of murder.
Ed Owens: Accused of child sexual abuse, Owens failed one polygraph but passed a subsequent one, illustrating the inconsistent nature of the test.
