According to the coroner six month-old Lourdes Duvall's death was ruled an accident. The little girl died from heat stroke. Someone left flowers and a small teddy bear next to the parking lot at LSU Heath where the little girl was found yesterday afternoon by her father. She was still strapped into her carseat. But this isn't the first time a child in the Arklatex has died after being left in a vehicle. Back in the summer of 2006 three children died after being left all day in vehicles. Officials decided not to charge any of the parents in those cases. For any parent forgetting a child in the back seat of a car is a horrifying mistake, but the bigger question is, is it always a crime? Caddo Parish District Attorney Charles Scott was asked how they determine negligence in a case like this. "Criminal negligence normally is when someone is impairment because they're out driving while they are intoxicated or they're driving while they're under the influence of drugs or things of that nature and a horrible accident occurs because of that impairment," said Scott. Scott says he can't go into further details on this tragic event, because his office hasn't received any paperwork from any of the investigating agencies.
