Donald Schmalzbauer, while a trooper with the Minnesota State Patrol, completed accident reconstruction training in 1984 and was granted court expert witness status in 1985.  He acquired full accreditation with the Accreditation Commission for Traffic Accident Reconstruction in 1994. As early as 1995, he implemented forensic mapping utilizing a total station in the Accident Reconstruction Program for the State of Minnesota.  In 2000, he attended the inaugural class on the Crash Data Retrieval System (CDR) held by Texas A & M at the Michigan State Police Academy in Lansing, Michigan.  

Don has been a long-time active proponent of photogrammetry for reconstruction in accident and crime scenes.  

He is a member of the Midwest Association of Traffic Accident Investigators (MATAI) and the International Association of Reconstruction Specialists (IAARS).


Forensic Mapping Utilizing a Total Station

The ACTAR certified instructors and investigators of Forensic Reconstruction Services have been using Forensic Mapping with CAD software programs since the introduction of these technologies to the forensic field in the mid 1990's. These instructors have been prominent in developing industry standards.



Early History of Total Stations used in Accident & Crime Scene Reconstruction

While serving as the sole investigator for the Minnesota State Patrol's St. Paul District in 1993, Sgt. Donald Schmalzbauer was offered a Geodimeter® Total Station that had been previously operated by the Minnesota Department of Transportation. Not averse to accepting a generous offer of a used machine, Schmalzbauer, was also aware there was no software that had been created for the field of accident reconstruction or crime scene investigation.

After receiving operational techniques from the MnDOT District Survey Section, he began manually obtaining the coordinate locations of evidence points and transferring them by hand onto scale diagrams. Subsequently, in 1995, Sgt. Don Schmalzbauer received Forensic Mapping training and Certification using a software program by Sokkia Corporation. Bringing a total station with CAD software to accident reconstruction would bring a level of accuracy not previously seen with hand measurements and drawings.

Forensic Mapping Utilizing a Total Station became integral to the State of Minnesota. In addition to the State of Minnesota, Sgt. Don Schmalzbauer instructed troopers from the South Dakota Highway Patrol in 1998.  He went on to teach reconstructionists and crime scene investigators from: Sault Ste. Marie, Ontario, Canada; Delaware State Police; Pennsylvania State Police; in Florida:  Florida Department of Law Enforcement, Bay County Sheriff's Department, Panama City Police Department, Orange County Sheriff's Department, Okaloosa County Sheriff's Department, Pensacola Police Department; in Illinois:  Kane County Sheriff's Department, St. Charles Police Department, No. Aurora Police Department, Batavia Police Department, Geneva Police Department, Elgin Police Department, Huntley Police Department, Sugar Grove Police Department; in Iowa:  Bettendorf Police Department, Davenport Police Department; in Minnesota:  Bureau of Criminal Apprehension, Metro Transit Police, Anoka County Sheriff's Office, Minneapolis Police Department Traffic Unit; North Dakota State Patrol; Pennsylvania State Police; in Pennsylvania: Manheim Police Department, and Savannah, Georgia Police Department.
