Our firm delivers astonishingly accurate and compelling forensic animations in cases of murders, officer involved shootings, automobile crashes, building collapses, assaults, accidents, bullet trajectory reconstructions, and mechanical failures. We also do financial evaluations of technology, including cases involving software copyright infringement, patent infringement, and company valuations. In addition, we do cases involving aviation accidents, including forensic analysis of autopilot and GPS data, pilot responsibilities, weather factors, and external factors such as runway surface and obstructions. The call is always free, the response is always fast, the science is always bulletproof, the work output is always legendary, and the rates are always affordable. As a group of laboratory physicists, software experts, and animation experts, our motto is "BECAUSE ACCURACY MATTERS".
