Evidence Collection To properly document the scene and evidence, State Patrol Crash Reconstructionists relied on several techniques to collect data including: 1. Forensic Mapping Total Station Diagram Generation 2. Photography At scene Aerial photography At impound facility 3. Crash Data Retrieval System
Forensic Mapping Crash Scene Two (2) Total Stations were utilized to map Sheboygan County crash scene. Survey Statistics: 1653 total scene and vehicle data points. Scene length: approx. 3700 ft. Crash Zone drawing software used to diagram scene.
Forensic Mapping Crash Scene Scaled damage profiles diagrammed for all involved vehicles.
Forensic Mapping Crash Scene Scaled diagrams then completed for primary crash areas.
Forensic Mapping Crash Scene Plotters used to print large-scale diagrams for collision reconstruction, analysis, and news conferences.
Photography Vehicles and scene extensively documented through photographs and photo logs. Vehicles also photographed and detailed at impound facility.
Photography Vehicle undercarriages also photographed to assist in determining a fire source.
Photography Overhead photos taken of each involved vehicle using a cherry picker bucket truck. These photographs allow vehicle damage profiles to be seen.
Photography Overhead photograph and CAD scaled damage profile diagrammed by reconstructionists.
Aerial Photography State Patrol aircraft have been used to help find lost persons, vehicles, and in drug interdiction. Crash reconstructionists utilize aerial photographs for evidence documentation and scene overviews.
Aerial Photography Example By showing advance warning signs, aerial photography was used in this Kewaunee County case to prove criminal negligence. STOP Casco / Brussels STOP AHEAD JCT C
Sheboygan Crash Aerial Photos On October 11 th, State Patrol Pilot Dennis McConnell was dispatched to Sheboygan County for aerial photographs. A private company also deployed fixed-wing aircraft to take pictures of the scene. Offered digital and plotted images to the State Patrol at a cost in excess of $900.00
Sheboygan Crash Aerial Photos Photographs taken from the State Patrol aircraft were used by reconstructionists for documentation.
Crash Data Retrieval System In 2001, the Wisconsin State Patrol purchased the Vetronix Crash Data Retrieval System. CDR System allows reconstructionists to access crash data from vehicle Event Data Recorders. System was utilized during Sheboygan crash investigation.
Sample Sheboygan CDR Data Driver of Impala stated she was traveling very slowly when she was hit from behind. CDR download confirmed driver s s statement.

I. Media challenges Intensity of media coverage Location of crash Between two largest media markets in Wisconsin Green Bay and Milwaukee Three major groups involved Traveling public commuters and tourists Crash occurred during peak travel time on a major tourist route. Friends and families of the victims Law enforcement and rescue personnel
II. Crash study I-43 weather related crash data 1000 900 800 700 600 500 400 300 200 100 0 971 754 730 636 189 100 106 32 Number of crashes Not listed CLEAR CLOUDY SNOW RAIN SLEET WIND FOG
II. Crash study Fog related crashes by county 7 6 Sheboygan Manitowoc Brown Ozaukee 6 13
II. Crash study Fog related crash data Other contributing factors 5 involved drivers influenced by alcohol 18 were during dawn/dusk/dark conditions 22 involved icy or wet road conditions Types of crashes 22 were single vehicle accidents 6 were rear end collisions 3 were same direction side collisions 1 was an angle collision
II. Crash study In conclusion Findings Not an unusually high number of crashes on this segment of I-43I Fog is not a major factor in crashes that do occur As a result Signs or flashers would not necessarily prevent crashes If signs are too prevalent, people will begin to ignore them. Closing the road is a last resort that is not recommended Law enforcement should have final say
