Administrator of test has been on FOX several time. He's been doing the test for over 28 years. Has taught the technique at the FBI school. Sent his results to the man who invented the test (He reaffirmed his results). Works for several notable LE agencies.......Credentials are the very best.... Did not previously know or keep in contact with the family. They didn't do it!
So what. Polygraph's are ridiculous.
If,during a test conducted by your lawyer,you're asked "did you kill your wife?" (and you did) you don't care in the least if the polygraph indicates you're lying or not.Your lawyer isn't going to tell anyone.
Conversely,if the polygraph is being done at police headquarters you're going to be nervous.But when asked "did you kill your wife?" and the truth is that you didn't,neither your heart rate nor your respiration rate will be any higher than it was when you were asked "were you born in this country?"...whereas it would jump if you *did* kill her.
I'm certainly not sure if either of them did it.However,I strongly suspect that at least one of them know something about the crime.
And you watch...the story that the guy in Thailand is telling will collapse like a house of cards with a few weeks.
I think his last name is Gell. (could be Gill)
