For example, if you are driving and have a seizure, lose control of your vehicle, and strike a pedestrian, you should not be convicted of homicide, even if the pedestrian dies. The seizure and your loss of motor skills was involuntary. You did not have physical control over yourself or the vehicle. However, if you knew you were prone to have seizures and drove anyway then you may still be convicted. Consult with a Philadelphia criminal defense lawyer to assess whether the state is able to prove the existence of a voluntary act. Call the Law Office of Mark D. Copoulos at (267) 535-9776.
