Missing Woman 911 Call/Radio Interview

Lie detection is not just about being able to detect deception but also focuses on being able to detect truthfulness.  When someone goes missing everyone should start out as a suspect.  Being able to detect truthfulness as well as deception could help an investigation progress more quickly.

Katelyn Markham, a 22 year old college student from Fairfield, Ohio, disappeared on August 14th, 2011.

John Carter, the fiance of Katelyn Markham, is a prime suspect in the investigation.  In a radio interview Carter stated that he understands that the Fairfield Police Department have not ruled out any suspects and that anyone close to her will be under investigation.

The couple, who have been together for 6 years, was planning on getting married after Katelyn graduated from college this September.

Carter has yet to do an in-person interview.  Below is the 911 call and a radio interview he gave a week after the mysterious disappearance of his fiance.

In the radio interview Carter stated,   “I don’t need a lawyer because I did not do anything”  He also uses the past tense in reference to Katelyn, “They [her parents] really loved her…”

We blogged in the past about  “statement analysis”.  Our Determining Mental States from Tone of Voice Part 1 and Part 2. talks about the analysis of verbal statements to identify meaningful content areas where “there is more to the story than is being told”

What are your thoughts on the 911 call and the interview?

Do you detect Truthfulness or something else?

Fetal Facial Expressions

Many people have heard of the endearing term ‘baby face”.  New scientific findings reveal that facial expressions begin even earlier than with newborn babies.  Science suggests that complex combinations associated with recognizable facial expressions occur as a fetus develops in the womb.

This new study reported on by LiveScience shows that as a fetus develops their facial expressions become very complex and can be recognized as combinations associated with known facial expressions.

Does this reinforce the universality of the seven basic facial expressions of emotion?  Well, more research needs to be conducted to confirm that but it is interesting.

Lead researcher and senior lecturer at the University of Durham in the United Kingdom, Nadja Reissland noted that these facial expression don’t necessarily mean that the fetuses were experiencing emotion, “We can see the expressions which we can recognize; we can’t say whether the fetus has emotion.  They have yet the cognition necessary to have the emotions.”

The study, which appeared in August in the journal PLoS ONE, used 4-D ultrasound images to track the facial motions, and it’s main focus was on expressions of crying and laughing.  However, Reissland is looking into future research on additional facial expression of emotion such as anger and sadness.

Truthfulness Detection

Lie detection equipment in airports is old news, but the use of thermal imaging cameras and powerful software to covertly spot potential deception is not.

An undisclosed airport in Britain is implementing this new technology that keeps an unwitting eye on people entering the country by scanning passengers for signs of truthfulness.

Mail Online News has reported on Britain’s new security defense.  This covert operation, if you will, could be used at passport control stations and in customs interview rooms.  The “new” deception detection tool has a greater advantage than the current tools such as electronic body scanners and metal detectors because it is being implemented without the knowledge of the person in question.

This device reads tiny changes in facial expressions such as eye movement and micro facial expressions that have corresponding reactions in the brain, which cause changes in the patterns of blood flow around the face.  The changes in blood flow to the face are picked up by thermal imaging cameras.  These “truthfulness” measurements can prove to be useful not only in airports but in a variety of places such as schools and business conferences.

The system’s designer Hassan Ugail, a professor of visual computing at the University of Bradford, commented on this software, ‘In an interview you can be talking to a person, then you basically just press a computer button and say:  “Was this person lying or not?”’

Detecting deception with just a click of the button can be misleading.  What do you think about this type of software?  Do “real” people also need to be trained to understand the nuances of human behavior for this to be a double edged sword for criminals?

Professor Ugail goes on to state, “What we try to do is experiment with the face itself, but it is purely non-invasive, which means the person is probably not aware the measurements are being taken.”

This system is still being developed but Ugail and his colleagues have claimed a 60-70 percent success rate.

What are your thoughts on this non-invasive lie detection technology?
