Immediately after her incarceration, Darlie had demanded that she be given a polygraph� test, which the police agreed to administer. When she was informed that her husband Darin could not be present in the room during the test, she withdrew her request. However, she again changed her mind on advice from her defense team, but with a stipulation: that before she take the polygraph she exercise her right to take a private test first.
The results of that test were never formally released, but Darlie and her mother were seen immediately afterwards, sobbing relentlessly.Barbara Davis on Darlie's polygraph (from Precious Angels, p. 179) "The family collectively had been notified that Darlie was going to take the test. Mama Darlie waited at the jail to visit with her daughter as soon as the six-hour test was over. When the deputy escorted Darlie back to her cell, mother and daughter embraced and Darlie began to sob. Curiously, Mama Darlie would vehemently deny she ever knew about the polygraph test. Instead, time after time before the case went to trial, she protested that the police were refusing to give Darlie a polygraph test. Darin told the family the next day that he couldn't tell anyone the results, by order of the court-appointed attorney. Darin said Parks had advised him it would be best not to talk to anyone about the test results."
