Mya Lyons' Father Questioned, Submits To Lie Detector

2008_07_25_mya.jpgRichard Lyons, father of murdered 9-year old Mya Lyons, was questioned by police on Thursday and submitted to a polygraph test according to his sister, Dawn Douglas. Police officers visited Richard at his Auburn Gresham home and asked if he would come in for questioning. Lyons complied and was released a few hours later. Douglas also said that, according to Lyons, other family members are being submitted to polygraph tests as well. Results of Lyons' test were not yet known. So far, Lyons and his family have cooperated fully with police. According to Douglas, "They said this is to make sure they're covering their bases...to put that rumor that the family had anything to do with it to rest." Police are also pleased with the cooperation they've had from the family to this point.

Chicago Police spokeswoman Monique Bond declined to discuss the interview, but she did say: "The family is very cooperative. We've been talking to a number of individuals, including family members."
Last weekend, a "person of interest" in the case was questioned and released by police. And earlier this week, there was excitement over a knife found near the crime scene, though there is still no word on whether or not that knife is connected to the case or a possible murder weapon.

Um, I hope that whole family is excercising their right to counsel. Polygraphs are sooo tricky. I would never take one, especially without a lawyer present.

Wow! Someone invented an actual "lie detector"!?!

He probably submitted to a polygraph examination. Polygraphs are not "lie detectors" - they're gizmos that track various physiological data such as heart rate and breathing. From that data, a human interpreter arrives at what the Supreme Court called "an opinion" about whether or not the individual was attempting to be deceptive. Polygraphs are notorious for both false positives (claiming someone is lying when they aren't) and false negatives (missing when someone is lying). On top of all that sloppiness, there are a variety of ways that it can be administered (in terms of questioning strategy) and the tone of the person asking the questions can have a huge impact on the "results."

Basically, polygraphs have more in common with the Scientology organization's "e-meter" than they have different. Please don't call it a "lie detector" and there are no "test results," only the opinion of the person who administered it.

Jenny:

Polygraphs are used only as a means of getting an edge on a "person of interest" or suspect. It's a tactical move, since they are inadmissible and generally about as effective as tea leaves.

I, sadly, thought that it was someone close to this girl from the word go. The timeline has always been very suspect.

Whoever did this...no...no words for the kind of hell they deserve.


Has it been established for sure that she was not sexually assaulted? Last I heard, the news was that she was not but Why would someone just kill a little girl like that?

When I first heard this story, my immediate thought was that the father did it. It makes no sense that she went to bed and then was found in the alley a short time later...now I'm thinking that maybe someone else snuck inside the house while everyone was outside and hid inside of her bedroom and took her out when everyone in the house was in bed.

Maybe the father has some 'iffy' associates. What, what what was the reason for this? It just makes no sense.

Ingrid - Honestly, I think there was a point when in the same day, either the Trib or ST said she WAS while the other paper said she WASN'T sexually assaulted.

Lie detectors are generally pretty accurate,anywhere from 80-90%, which is why as an investigation tool, it is the same as confessing basically.

Get a lawyer. NOW.

Jenny:

Can you cite a source on that statistic? A 1997 survey of psychologists found a 61% accuracy average. Little better than a coin toss.

(Yes, it's USA today, shrug)

Getting a lawyer is ALWAYS the first thing you do when the police want to talk to you about ANYTHING. Even if you're innocent as a lamb.

Ol' Daddy did it, those crocodile tears aren't foolin' anyone!
