Justin DiPietro, the father of 21-month-old missing toddler Ayla Reynolds, took a polygraph test shortly after his child went missing, Maine State Police confirmed on Friday.

DiPietro, in an interview with The Morning Sentinel, said I asked for a polygraph on day one. I've taken one, and the results, I was never allowed to see them. It's something you're going to have to ask law enforcement about.

However, Maine State Police spokesman Steve McCausland said that DiPietro was informed of his test results and added he was baffled by DiPietro's statement.

He knows how he did, because we told him, McCausland said, To say that he didn't know is just not true.

However, McCausland neither confirmed when DiPietro gave the test nor did he say if he passed or failed. He also did not elaborate on what questions DiPietro was asked during the test. Instead, he would only say that the polygraph test results were a tool which could be used in police investigation but cannot be used in court as evidence.

DiPietro, 24, said he took one polygraph exam, which was administered by a single detective. He wouldn't say what he was asked but briefly described the equipment.

You've got things on your fingers, you've got things across your chest, he said, adding he sat on a seat pad that was part of the polygraph equipment.

I wanted to see the results myself but didn't physically see the results, DiPietro also said, noting, They're not letting me see them. Why don't they let the public see them?

McCausland did also say that test results could be difficult to read for the average person.

It is lines on a paper, similar to an electrocardiogram report, he said, The polygraph operator knows the results, but there's no transcript or written text that goes with it.

Earlier, state divers searched for the missing toddler in the icy Kennebec River and Messalonskee Stream.

We've ruled out no scenarios, and ruled out no one in connection with the toddler's disappearance, McCausland said.
