Accident Investigation Unit
Lieutenant Robert Welch
The Accident Investigation Unit is tasked with performing scale diagramming and detailed analysis of motor vehicle accidents involving fatalities or serious bodily injury. These officers attend advance training in accident investigation in which they are taught to apply mathematical formulas to the evidence and measurements of a crash scene to determine the sequence of events leading up to the crash. These officers also receive training in the use of laser mapping equipment to precisely diagram the scene of a fatal/serious bodily injury accident for evidentiary purposes.
