October 12, 2021 8:00am to October 14, 2021 5:00pm

The Course Overview

3 - Day Course

Forensic  Statement Analysis is a tool that is highly effective in the detection  of deception and the identification of hidden information in a person’s  written or spoken statements. The analysis involves critically examining  the word choice, structure, and content of a person’s statement to  determine whether it is truthful or deceptive. As people intentionally  attempt to be deceitful, they use different words, phrases, statement  structure, and content in their statements.

In plain English….  this course will teach you, one technique at a time, how to identify  when and where someone is lying to you in a statement.  Then when you  conduct your interview, based on the findings from your analysis, it can  be much more direct and fruitful.

Using Forensic Statement  Analysis (a series of layered techniques) you will identify the  linguistic signals that differentiate deceptive statements from truthful  ones as your suspect subconsciously reveals information, he or she did  not intend for you to know. This course is very interactive with  significant hands-on, statement analysis practice

Topics Covered

Detecting Deception

The course will examine  verbal and nonverbal communication relating to increasing investigators’  ability to recognize and capitalize on indicators of deception in their  interaction with suspects, witnesses and victims.  Participants will discuss emotion and whether a specific emotion is appropriate for  specific circumstances.  Those in the class will view and discuss real examples via videos and photos of expressions and body language used in high stakes situations.   

Statement Analysis

The course will provide an  in-depth exploration of how and why people choose they words the say or write in various situations.  Students will learn how to analyze word  choice and narrative balance in order to better understand the investigative trail left by anyone who would attempt to deceive.   Participants will also learn to detect indicators of truth-telling to  assist in quickly assessing credibility.  The course will examine the  spoken and/or written words used by real suspects, witnesses and victims  in actual cases worked by the instructors.

This portion of the  course will allow students to analyze actual written statements and  determine areas of truthfulness and areas that may need further  exploration.  Since these statements are from actual past investigations  the outcomes are known so your evaluation can gain real and factual feedback. 

Interview and Interrogations 

“If you’re  going to interview, interview. If you’re going to interrogate,  interrogate.” There are two important parts of this lesson. The first is  that there are significant procedural differences between interviewing  and interrogation. The second is that if these procedures are  intermingled, the investigator will often be ineffective in  accomplishing the goals of either one.

This portion will discuss question formulation how to interact with a suspect for a confession.
