A Midtown pedestrian was killed by a van that had an improperly installed steering mechanism. During this trial, Dt Racioppo was able to show, through numerous high-quality photos and a series of court-admitted exhibits and clear testimony, how the improperly installed steering gear assembly failed. He was also able to demonstrate how this improper installation would have been evident to the operator. This testimony was vital in establishing the Negligence aspect of the charge, which ultimately resulted in a Manslaughter Conviction.

A pedestrian was struck and killed by a speeding vehicle on Forest Ave in Staten Island. This speeding vehicle's operator was under the influence of drugs and collided with the pedestrian, then another vehicle which created a crime scene over a quarter of a mile long. Dt Racioppo's methodical investigation of this scene allowed him to reconstruct every aspect of this complex collision and prove the numerous aspects of the charge necessary for a conviction of Depraved Indifference Murder.

An NYC Traffic Agent was struck and killed by a van with bad brakes. The case went to trial, and Dt Racioppo was able to effectively demonstrate that while there was a brake failure, the failure was due to neglect. He was also able to demonstrate how this neglect would have been known to the operator through sound and other signs which the driver ignored. His unique testimony proved the negligence needed for the charge of Criminally Negligent Homicide.

A driver was arrested and charged with two counts of Negligent Homicide for driving under the influence and on the wrong side of the road at an excessive rate of speed. The defense hired an expert to muddy the waters and confuse the jury with complex accident reconstruction mathematics and diagrams. Mr. Racioppo was able to prove that the defense's expert used multiple accident reconstruction formulas incorrectly and obtained formula input utilizing flawed methodology. He was also able to demonstrate to the jury, in a common-sense manner, the conditions required to utilize such formulas and how their use, in this case, was inappropriate. He was then able to construct the dynamics of the collision and present the violating factors needed to sustain a conviction for the Prosecuting Attorney of the State of Hawaii.
