The polygraph testing that supported Gareon Conley’s assertion of innocence ended at 7:58 p.m. Thursday — all of two minutes before the start of the NFL draft.

A women’s accusation that the former Ohio State cornerback sexually assaulted her in a Cleveland hotel on April 9 had thrown Conley’s future into question.

Conley said he was innocent in a statement Wednesday. On Thursday, Conley’s agent Adam Heller said, the Baltimore Ravens requested a polygraph.

So Conley’s attorney, Kevin Spellacy, called polygraphist Bill Evans. Evans was on the road in eastern Ohio on business and was unaware of the accusation regarding Conley. He and Conley met at his Akron office shortly after 6 p.m.

Evans told The Dispatch that the polygraph testing centered on two disputed issues: the location where Conley first met the accuser and whether they had sexual intercourse.

According to the Cleveland Division of Police report of the incident, the woman said she met Conley at the Westin Hotel and that he raped her. Conley disputed the latter and said they met earlier that night at a restaurant.

Evans said that both his pre-test discussion with Conley and the formal polygraph results support Conley’s statement.

“I interviewed Gareon at length,” Evans said. “My impression of his clinical behavior alone, separate and apart from any polygraph testing, was that he was not deceptive. He didn’t seem to be practicing any attempt to avoid questions. He was very direct and responsive to my questions in the pre-test interview, which is sometimes a telling stage. In this case, it didn’t raise any suspicions with me.

“There didn’t seem to be any inconsistencies regarding his stories. Sometimes, there are breaks in details that differ from time to time to time because a person can’t keep those facts straight if they’re not telling the truth about them.

“In the polygraph testing itself, he was truthful in respect to those questions I presented to him.”

Evans started his company, Poly-Tech, in 1977. He is also an attorney and educator who has worked for both defense attorneys and prosecutors. Evans said studies have shown that polygraphs have a 93 percent accuracy rate, depending on factors including the polygrapher’s experience, equipment and expertise.

“Like with anything else, there’s variation of findings that are possible,” Evans said. “It’s cut and dried in terms of the analysis. A person is either telling the truth or deceptive or they’re inconclusive. Of those three options, he (was determined to be) telling the truth, which in polygraph terms is ‘no deception indicated.’”

A polygraph measures physiological changes such as heart rate, blood pressure and breathing patterns in response to questioning. Each part of the test takes about four minutes, he said.

“I finished two minutes before the draft. There was a lot riding on this. He knew that. I knew we were doing the exam right at the 11th hour. I think he was concerned about trying to get the examination completed before then.”

Conley’s representatives spread the word to NFL teams about the polygraph results. Shortly before 11 p.m., three hours after Evans finished, the Oakland Raiders selected Conley with the 24th pick of the draft.
