WHAT DO I DO?
While I am a general Accident Reconstructionist, I focus on criminal defense such as Watson Murders, Manslaughter and Felony DUI. When a party to a collison is arrested for a felony crime, the prosecution has at its disposal many well trained, experienced and capable Collision Reconstruction experts. Most local police departments have in-house experts. If not, they have access to Deputy Sheriffs from their county and members of the Highway Patrol or State police. If need be, they can get technical support from the State Department of Justice or even the Federal Bureau of Investigations. With all this expertise arrayed against them, who does the Defendant have? Who reviews the police investigation? Who ensures proper techniques and analysis has been accomplished?
Defense of felony criminal charges requires a combination of legal and technical analysis. The advent of the Watson Murder case allowed for very serious charges in select fatal collisions. The subsequent Olivos case refined what is required to sustain a conviction. In the Olivos case, the Court refined the standard set by Watson define the difference between negligence and wanton disregard for life as the mindset of a driver with wanton disregard knows, or reasonably should know, that his driving will result in death, but he doesn’t care. How does one disprove the allegation that the driver didn’t care? The reconstructionist must evaluate the driving pattern of the Defendant and determine what, if he did anything he did to avoid the collision.

RECENT CASES
In Los Angeles County, 2024, a driver accused of traveling 95 MPH in a 25 MPH school zone was involved in a fatal collision. He was charged with and prosecuted for one count of PC 187, second degree murder, 192(c) (1) PC Felony Manslaughter and 23013 VC, Felony Reckless Driving with Injury. After a thorough review of the techniques used by the investigating Officers, we were able to show their speed estimates were wrong, their at-scene investigation was deeply flawed, and their basic cause analysis was incorrect.
