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.
