In November 2016 I travelled to the United States to meet and interview Peter Hyatt.
Peter is a highly respected expert in statement analysis and in his work he teaches other professionals and assists law enforcement on criminal cases.
When we speak, the process of constructing sentences in our mind involves deciding which tense to use, which words to select from our vocabulary and what order to put them in.
This mental process all happens in a fraction of a second.
If somebody is constructing sentences from their experiential memory, ie, recalling something real that actually happened to them, the process of word selection follows particular patterns and characteristics, which can be easily identified by a trained statement analyst.
If however a person is fabricating and being untruthful when they speak, the natural cognitive process of choosing and ordering words is interrupted, because the mind must censor and insert artificial information in a very short time period.
This means the language of somebody who is fabricating is characteristically different and can be picked up by a trained analyst like Peter Hyatt.
He has analysed in depth an interview that Kate and Gerry McCann gave in 2011 and throughout the entire interview both Kate and Gerry it appears show signs of deception.
Not only that, Peter determines from their language what he believes to be what it is they are concealing.
The conclusions are shocking.
