It states:
In Virginia Vehicular Manslaughter or Vehicular Homicide arises when one person causes the death of another while driving under the influence of drug or alcohol in violation of Virginia’s DUI laws.
To be convicted of vehicular manslaughter in Virginia, the prosecutor will need to show proof that the driver charged with vehicular manslaughter was intoxicated and that that intoxication was the legal cause of the death.
It then lists types (a) through (f) of vehicular manslaughter. For all, the above must apply. For (c) Involuntary manslaughter
“c. 18.2-36 – Involuntary Manslaughter.
Most vehicular related charges of involuntary manslaughter involve actions alleged under 18.2-36 (3) (b)*. That would be accidently killing another during the improper performance of a lawful act. An example of Cheung vs. Com. In that case the Court of Appeals found that deliberate failure of a driver to disregard signs of drowsiness is evidence of a reckless disregard for human life.”
In this case, they determined that lack of sleep was a type of driving while under influence or intoxicated. They have determined that for over the counter and prescription drugs as well.
But Anne Scoolas was not under the influence of any substance or intoxicated. The Virginia law doesn’t apply to her situation and her lawyer is correct as far as I can see. I have a friend who was knocked off her bike into a ditch in Florida where she died. The driver did not even get a ticket. The US laws do not cover accidental vehicular manslaughter.
