The jury is deliberating the DUI death case brought against former Yankee catcher Jim Leyritz. Leyritz is accused of driving drunk, thereby causing an intersection collision that led to the death of the driver of the vehicle with which he collided.
The prosecution claims that Leyritz ran a red light and that his blood alcohol content at the time of the accident was .18, well above the Florida legal limit of .08, which is the same legal limit for an Illinois DUI. At the time Leyritz was tested, 3 hours after the crash, his blood alcohol content was .14.
The state (prosecutor) hired a toxicology expert who testified about the process of “reverse extrapolation”. Reverse extrapolation simply means that the expert worked the numbers backwards. He estimated Leyritz’s blood alcohol content when he was driving was .18.
On the other hand, Leyritz offered a spirited defense of the charges. First, no witness was able to state with certainty that Leyritz’s light was red. At most, they testified it was yellow when he entered the intersection. One witness was a passenger in Leyritz’s vehicle. The other was a pedestrian.
Furthermore, Leyritz had his own expert. This expert also relied upon reverse extrapolation and the concept of the alcohol absorption curve. The idea is that alcohol does not enter the bloodstream (and therefore effect the blood alcohol content) immediately upon drinking. It takes some time.
