6-year-old Nicole Rae Walker was killed in a hit-and-run in her Ft. Lauderdale neighborhood. Investigators find a link between habitual drunk driver Ken Pierce and the fatal hit-and-run. The prosecutor combines the talents of an accident reconstruction expert with a video specialist to create graphic demonstration of the moment of impact. This was the first case in which video in the courtroom withstood an appeal, and helped make video testimony viable in other cases.
