Katelyn Markham: Did fiance take a lie detector test or not?

Over the last couple of days there has been a lot of media reports about John Carter, the fiance of missing Katelyn Markham, not being truthful about whether he took a lie detector test or not.

John said he took one, shortly after Katelyn’s disappearance and then later, on the Nancy Grace show, he said he had not, but would be willing to.

Many web detectives that have been following this story very closely, knew immediately that there was a discrepancy, as they had heard him say he had taken one, too.

But, I had also heard that the test he had taken early on was a voice stress test and not a wire polygraph test that most people are the most familiar with.  When I heard that people thought he was lying about the test, I knew it was because they may have not know about the voice stress test.  

I believe that it was a miscommunication.  I don’t believe that John was being deceptive.  I think early on he took the voice test and referred to it as a polygraph and  somewhere between then and the Nancy Grace show he found out there was a difference. 

Then today, John’s mother Karyn Winkler said, “John has referred to this test as both a polygraph test and a lie detector test.  The detective working on Katelyn’s case said that often, people confuse the two with the terminology, and she is not surprised when someone she is working with confuses them or when someone in the community confuses them,” said Karyn.

This statement pretty much confirms my earlier beliefs, but I am sure some now will think that it is a coverup.  What do you think?

  1. There are a number of discrepancies in John Carter's story beyond the confusion over the polygraph test.

    In his original 911 call John said that he was with Katelyn until 11 or 11:30. In a radio interview he states that he was with her until midnight.

    The 911 call John says he contacted Katelyn's Father. On Nancy Grace the story is expanded to include contacting Katelyn's Father, Mother and a number of friends.

    Also in the 911 call John's story is that he went home, received a picture from Katelyn, and sent her a good morning email, as usual. He said he was concerned when he didn't get a response to his good morning email and figured Katelyn was busy. While talking to Nancy Grace, John told Nancy that he went out with friends, stayed up until 4 a.m. and slept until 4 p.m. How could he be concerned about not receiving a reponse to his good night email that morning if he didn't get up until 4 p.m.

    Is there something really off here, or am I missing something?

  2. I live near Fairfield where Markham disappeared from. I'm concerned as to the investigation by police in that city. I think we visualize 'Criminal Minds' 'Quincy' or 'Monk' with the various close to Katelyn, individuals.
    Her friends, co-workers, family and then …the boyfriend should all be spinning a tale that makes sense after a month; a methodical, repeated story of the events leading up to August 14. Every detail that has a discrepancy should be combed over again and again until it 'sounds' right to a real live professional DETECTIVE who is relentless in having it make sense–Columbo style.
    The boyfriend has brought up enough changed, different, new, dis-jointed information that I'd have him questioned enough to clear him or put him under enough suspicion to have him retained and retained, etc. There is a HUGE difference between being at work all day or sleeping in your apartment all day, while not hearing from your girlfriend.

    Let me have a stab at it….where WERE YOU Mr. Carter?
