MEET OUR OFFICERS
LEE JACKSON
PRESIDENT
Lee Jackson got involved with crash reconstruction in 1988 as a member of the Fort Worth Police Department. For over two decades he served in the Traffic Division where he investigated fatalities, injury, and property damage crashes. He spent seven years in the Traffic Investigation Unit (TIU), which was charged with investigating all fatality and hit-and-run crashes. While assigned to the unit, he started attending classes and seminars on the scientific principles of crash investigation.
In 1990, Jackson applied his expertise to a private-sector endeavor: Traffic Crash Reconstruction, Inc. This is a self-contained investigation unit that can be anywhere in the state, or bordering states, within 24 hours. In 2002, Jackson and a colleague were selected to start the Commercial Motor Vehicle Enforcement Unit for the Fort Worth Police Department and ultimately were certified by the Texas Department of Transportation to conduct DOT Level 1 inspections.
Jackson retired from the Police Department in 2010 and has turned his attention to education, and consulting in crash investigation and reconstruction on a full time basis. In 2012 Jackson won the first national ARAS 360 Forensic Animation Contest, and has generated numerous animations used in the litigation process.
Jackson has taught 5 different levels of accident investigation classes with more than 2,000 hours of classroom experience.

From 2010 until his retirement, he was assigned to the Traffic Unit, where his primary responsibilities were hazardous traffic enforcement, crash investigation, crash reconstruction, forensic mapping of major incidents, and enforcement of motor vehicle crimes. When he wasn't investigating crashes, he was enforcing the types of violations that often lead to them (speeding, stop signs, red lights, failure to yield, following too close, unsafe lane changes, illegal turns, cell phone use, etc.). He received numerous awards, recognitions, and commendations (93) throughout his police career, including being awarded Field Training Officer of the Year (3 times), Officer of the Year by area civic groups (5 times), and Mesquite Police Officer of the Year in 2012.
Throughout his career, he has investigated thousands of motor vehicle collisions. He has been trained in basic, intermediate, advanced, reconstruction level, and advanced reconstruction level collision investigation. He has received specialized training in motorcycle reconstruction, auto/pedestrian reconstruction, commercial vehicle reconstruction, human factors in crash reconstruction, use of Response software from Driver Research Institute (human factors software), video analysis, and crush energy analysis (speed from damage). As an instructor in the police academy, he routinely taught crash investigation, traffic direction, and traffic law to police recruits. While at the police department, he was asked to assist the Dallas County DA on several cases outside of his jurisdiction. Examples of this assistance are EDR validation though advanced reconstruction methods in a crash involving the death of a Dallas Police motorcycle officer and crush analysis in a notable pedestrian fatality in a Dallas mall parking garage.
