This case involves allegations of evidence tampering in relation to a commercial transportation accident. A shipping container weighing approximately 20 tons was being lifted onto a ship by an industrial crane. As it was being hoisted up, the container dropped from a significant height killing 2 longshoremen and damaging the cargo inside. The crane had a DVR which recorded the incident. However, when OSHA attempted to retrieve the digital video footage from the crane, it was unavailable. It was alleged that the crane operator tampered with the video footage in order to conceal an operational error. An expert in digital video forensics was sought to determine whether or the digital video recorder was tampered with and, if possible, to retrieve the footage.
