About Us

LIES, LLC Linguistic Interrogation Expert Services was established in 2001 with the vision and commitment to develop professional training programs that improve the ability of investigators to obtain accurate and reliable information from people during investigative interviews, which is the primary source of evidence and information obtained during most criminal investigations.

Over the years we have expanded into consulting, investigations and research as well, which supports our mission by applying the information we teach and what we learn through research directly within our investigations. This is a constant feedback loop for improvement all around. Our teaching and research improves the effectiveness of our investigations, and our experiences within our investigations influences and refines our training courses. And all of this improves our services to our clients as professional consultants. Our instructors, investigators and associates are highly trained seasoned detectives and investigators who share a passion for investigative interviewing, criminal interrogations, investigative statement analysis, credibility assessment, detecting deception and finding the TRUTH.

To ensure that you gather the most accurate and reliable information during your investigations, you must make sure your training is the absolute best and that it is supported through academic research as well as effective application within the field. 

"When you need to know the TRUTH, your training should be from LIES"

Mission Statement

“To help investigators reach the truth, whether it is through our training programs, investigative services or professional consultation.”

The above statement may sound simple…”to reach the truth”…but at times the truth is just outside an investigators grasp because they are running in circles, busy pursuing paths leading to dead ends or false conclusions. The discovery of the truth can be made only with the proper mindset and effective training. Lacking either one of these will open you to being misled and put your investigations at risk of being suspended without closure, or worse, leading to inaccurate conclusions, false confessions and wrongful convictions.

Let LIES be your partner pursuing TRUTH!
