STATEN ISLAND, N.Y. — Pedro Abad’s blood alcohol content was through the roof – as high as .273 percent, or more than three times the legal limit – when he plowed into a tractor trailer while driving the wrong way on the West Shore Expressway two years ago, killing two of his passengers, according to testimony in court Friday.
William Dunn, a prosecution witness and forensic pathologist, said he extrapolated that staggering number based upon the blood alcohol content found in a vial of Abad’s blood taken at the hospital nearly 90 minutes after the deadly wreck on March 20, 2015.
But when defense lawyer Mario F. Gallucci challenged him, Dunn admitted extrapolation requires making certain assumptions.
Here are highlights from Friday’s testimony:
ABAD’S BLOOD ALCOHOL CONTENT HIGHER THAN REVEALED?
Dunn is the assistant director of forensic toxicology at the city’s Office of the Chief Medical Examiner.
Within a week of the wreck, his office was provided three vials of Abad’s blood taken at Richmond University Medical Center in West Brighton after the crash.
Dunn tested one vial for ethanol, which is found in alcoholic beverages, while another vial was tested for drugs. No drugs, including painkillers, were detected, he said.
Dunn said his tests showed Abad’s blood alcohol content was .24 percent when his blood was extracted at the hospital at 6:17 a.m. on March 20, 2015.
He said he determined that number by running two tests of the blood samples, which showed a blood alcohol content range from .226 percent to .264 percent.
Dunn said the findings come with a 99.7 percent confidence rating.
Dunn said he extrapolated Abad’s blood alcohol content at the time of the crash from the hospital reading, factoring in the rate of alcohol elimination from a person’s system.
He said a social drinker
