Polygraph Lie Detector News

Here in New Zealand we don't feel able to publicly share with you our polygraph lie detector testing casework out of respect for the privacy of our clients.

But polygraph lie detector examination results are often reported by the news media in the USA, especially when the results of the polygraph have been admitted as evidence or testimony, by the Courts. (It is a fallacy that the polygraph is not accepted by US Courts).

The following cases demonstrate what a powerful investigative tool polygraph testing is.

Man cleared with the help of polygraph after 22 years in prison
6 February 2014

Anthony Yarbough of New York was released from prison today after spending 22 years in jail for the murder of his mother, half-sister and her friend.

In 1992 at the age of 18 he had made a false confession to the murders and had been locked up ever since. Three months ago he passed a polygraph examination and then DNA testing later cleared him, too.

On the morning of 18 June 1992, Yarbough came home from a night of partying in Manhattan with his friend Sharrif Wilson to find the bodies of his mother, Annie Yarbough, 40, her daughter, Chavonn Barnes, and Latasha Knox, both 12, stabbed and strangled with electrical cable.

He was arrested for those crimes although there were no witnesses, physical evidence or real motive connecting him to the crimes. Wilson, a scared boy of 15, would eventually confess to committing the murders with Yarbough. But in 1999, while both were still in prison, another woman was murdered in Brooklyn in a similar fashion.

Last year, the Medical Examiner’s Office discovered that the DNA found in the woman murdered in 1999 matched the DNA found under Yarbough’s mother’s fingernails in 1992.

Two lawyers who had been working on the case for four years appealed to the court and the Brooklyn District Attorney’s office to free both men. Wilson recanted his false confession and passed a polygraph requested by the Brooklyn District Attorney, before the DNA match came back.

Polygraph Examiners regular assist the “Innocence Project” – the international organisation dedicated to exonerating wrongfully convicted people.

9 September 2013

Kevin King has been charged with the murder of his three-month old son after failing a polygraph examination and then confessing to injuring him. The infant died of head injuries and internal injuries.

Police had asked King to take a polygraph test because they doubted the veracity of the story he first told them about how his son was hurt. King first told police that whilst walking down a set of stairs he twisted his ankle and fell on the child, hitting him in the head with his knee.

After being informed he had failed the polygraph test, King gave a written statement admitting he squeezed the baby and had thrown him to the floor because he was angry the child would not stop crying while he was playing video games.

Serial rapist finally admits offending after failing Polygraph test
24 September 2013

A Court in Pennsylvania today heard that it was only after failing a polygraph test that 20 year-old David Martinez began to admit he was responsible for the serial rape of teenage girls he met on Facebook. The next day he wrote letters of apology to his victims, saying he "needed help with his sex addiction problem."

Martinez faces charges he raped five women and girls he met through social media, the youngest of whom was 14 and two of whom were pregnant.

Martinez was initially charged in only two cases, which involved 17- and 14-year-old girls who said he raped them at his home. One of the cases had previously been closed as unfounded, but was reopened after the second girl came forward.

After his arrest, the District Attorney issued a public call asking other potential victims to contact police. That led to three more victims coming forward.

Police said the assaults spanned from 2011 to January 2013. Martinez would meet the girls online, exchange phone numbers with them, and eventually arrange face-to-face encounters at which he wouldn't take no for an answer, and raped them.

Martinez’s lawyer sought to have the polygraph confession ruled inadmissible but Judge Emil Giordano found Martinez knowingly waived his rights before taking a polygraph and later signing confessions to two rapes.

The Judge ruled Martinez drove himself to both interviews, where police explained in detail he was not under arrest, did not have to answer their questions and that anything he said could be used against him in a court of law.
