Verdict in DWI Case Challenging Nassau Crime Lab Results

A man accused of causing a fatal car accident while driving drunk has been convicted of a lesser charge in a case that challenged the accuracy of blood-alcohol testing at a troubled Long Island crime lab.

It's the first verdict in a drunken driving case since the Nassau Police Crime Lab was closed in February. An investigation found numerous problems there, including that it improperly calibrated the instrument that measures alcohol in blood.

Jonathan Davis was acquitted Tuesday of manslaughter but found guilty of vehicular manslaughter. He faces up to 7 years in prison when he's sentenced June 3.

Prosecutors said he was speeding when he caused the 2009 accident that killed a nurse driving home from work. They say the calibrating instrument wouldn't have affected blood-alcohol results.
