Typically, the accurate reconstruction of a crime or accident requires the existence of sufficient physical evidence left at the scene. Skid marks, scrapes and gouges, dents and paint transfers, fluids such as blood or gasoline, bullet shells and casings and even vehicle parts are often used as the foundational basis for conclusions about how the event occurred. However, sometimes these types of physical evidence are not present or are of insufficient quality to allow them to be used as the basis for reconstruction. Fortunately, many of today's vehicles and roadways are equipped with video surveillance cameras, as are many of today's buildings and businesses. In addition, the populace is carrying and using hand-held video cameras with increasing regularity. These recorded videos can be used as the foundational basis for determining the factors needed to reconstruct the event properly. PSI has developed the Video Sequence Analysis (VSA) that allow the use of the captured video footage to determine factors such as Speed, Direction of Travel, Acceleration/ Deceleration, Points of Impact & Rest and position of objects and people over time. Any type of video can be used including on-board cameras installed on municipal vehicles, security camera footage from facilities and hand-held footage captured by witnesses. Combining this data with the power of Laser Scanning & the 3D Working Model (both links) allows a complete reconstruction of an event, even those with little or no physical evidence other than the video footage. PSI has published numerous articles on this subject. A sampling of this written material can be obtained by clicking on the link below.

Ask us about our recent 12 to 0 DEFENSE verdict where PSI’s VSA was a key piece of evidence used by the Jury to come to their decision in UNDER 30 MINUTES!
When we decided to get PSI involved in producing an annimation we had no idea they'd have the impact they would. We were amazed.

Results: The defense attorney, assisted by the expert's comprehensive reconstruction, and PSI's computer generated simulation, was able to determine that the physical evidence corroborated the peace officers' version of the incident and conclusively established that the officers' use of deadly force was reasonable.
