Heath Jackson graduated from the University of Texas at Arlington in 1990 with a B.A. in Criminal Justice. He spent two years as a parole officer for the Texas Department of Criminal Justice – Pardons & Paroles Division, where he supervised offenders on parole. From 1992 to 2020, he was a police officer with the City of Mesquite (Texas). From 2010 until his retirement from the police department in 2020, he was assigned to the Traffic Unit. His responsibilities included hazardous traffic enforcement, crash investigation, crash reconstruction, and enforcement of motor vehicle crimes. While in the traffic unit, he spent his shifts investigating motor vehicle crashes. When he wasn’t investigating crashes, he was enforcing the types of traffic violations that led them: speeding, stop signs, red lights, fail to yield, following too close, unsafe lane changes, etc. His responsibilities included filing criminal charges related to motor vehicle crashes and he routinely testified in court (grand jury, municipal court, criminal court, civil court, and depositions). Throughout his police career, he investigated thousands of motor vehicle collisions. He has been trained in basic, intermediate, reconstruction level, and advanced reconstruction level collision investigation. He has received specialized training in motorcycle reconstruction, auto/pedestrian reconstruction, commercial motor vehicle crash reconstruction, human factors in crash reconstruction (human perception-response), Interactive Driver Response Research software (PRT estimates based upon research), video analysis, and crush energy analysis (speed from damage). He has been trained in total station mapping, laser scanning, and 3D computer diagramming and he has been trained by FARO as a laser scanner operator. As a police instructor, he routinely taught crash investigation and traffic law courses in the Mesquite Police Department Police Academy. He was a master level RADAR and LIDAR instructor for Mesquite Police Department. He has received training from Collision Safety Institute (CSI) as a Crash Data Retrieval (CDR) Technician I/II and Crash Data Retrieval Analyst. This is specialized training to retrieve crash data from electronic modules (AKA “the black box”) in crashed vehicles and analyze that data as part of a situationally complete reconstruction. While at the police department, he assisted the Dallas County District Attorney’s Office on several cases outside his jurisdiction. Examples of this assistance was EDR validation through 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. He is a member of the Texas Association of Accident Reconstruction Specialists (TAARS), the National Association of Professional Accident Reconstruction Specialists (NAPARS), the International Network of Collision Reconstructionists (INCR), and the Crash Data Retrieval Tool Users Group. He is also included in The Crash Hub and the Round Table Group (formerly Thomson Reuters) crash expert directories. He received numerous awards, recognitions, and commendations 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 Department Officer of the Year in 2012. He owns Closing Speed Consulting, a state licensed investigations business, which provides crash reconstruction consulting services to insurance companies and attorneys seeking answers to motor vehicle crashes.
