  • Investigative Statement Analysis


Investigative Statement Analysis is a method for detecting likely deceptions and omissions in language. In this concise, practical one day course, students will learn the elements of Statement Analysis and how to apply them for more effective interviews.  We will analyze a variety of written and spoken statements – including suspect interviews, criminal interrogations, press conferences, 911 calls and ransom letters.  Because our work is not just to identify deception but to overcome it, we will then discuss how to use a subject’s own language to focus our interviews and investigations.

Investigative Statement Analysis complements investigators’ understanding of interview & interrogation methods and non-verbal communication.  This training is designed to enhance the work of detectives and investigators in the areas of: criminal investigations; internal affairs; background investigations; officer-involved incidents; corporate security and human resources investigations. Statement Analysis is particularly useful for investigators whose cases involve telephonic and audio-recorded interviews, transcripts, and written responses – when clues must be found in words alone.
