CHARLOTTE, N.C. -- For two days now, Casey and Sandy Parsons have told Dr. Phil their side of the story in the disappearance of Erica Parsons.
Wednesday, a bombshell poking holes in their story: Sandy failed a lie detector test.
NBC Charlotte asked a local expert to weigh in.
Missing or murdered? Dr. Phil tried for two days to solve the mystery of Erica Parsons, dramatically concluding with the results of a polygraph.
“You think he knows something he’s not telling us,” the talk show host asked the polygraph expert.
The lie detector expert revealed the teen's adoptive dad, Sandy, basically failed the test.
“He was what I consider strongly deceptive to those relevant questions. This wasn't even a close call. It was just quite clear,” the expert said.
Sandy's stepmother didn't seem surprised.
“In all honesty, I think there's more to that story than just a matter of deception. I think there are things that maybe he's not telling,” said Janet Parsons.
Veteran Charlotte homicide detective, Gary McFadden, is not working the case but is watching it closely, especially the nationally televised interview with Erica's parents. He said the body language was very telling.
“That they were lying, they were lying,” McFadden said emphatically.
He also shed some light on what the search last week could mean, after investigators seized Jon Benet Ramsey magazines from the family home.
“If you plan on doing something, you become fascinated with that particular crime...some people build their lives on it and build their case on how to abduct someone, cover up their tracks. What they did wrong in that case...so we won’t do it in our case,” he said.
But McFadden said the thing that will crack this case is when someone gets scared.
Janet Parsons said of her stepson, “He is a good man. A loving father. He really loves his children, this is just destroying him. I wish he would talk more.”
