Mom mentioned Cooper was not sleeping well past few days. What if Cooper was sick and dad knew he couldn't take him to daycare, but he knew he still had to be at work. I'm a mom of 4 and know some people do crazy things to try to get their kids into daycare even if they are sick. What if Cooper's dad knew he had to be at work for some project, but he had to take care of Cooper at home if he was sick and his wife couldn't get off work, so he tried to think of how he could keep Cooper "safely" in car while he popped into work for a bit? What if dad went in late to work. Dropped by for breakfast to get Cooper food and drink for the car, went in to work at 9:00, knowing everyone is probably already in work, thought Cooper was okay with some food and drink, maybe even cracked open windows, went to work, then went back to car at lunch to give Cooper more food/drinks, but then realized it was too late and tried to cover his tracks. Either this way or premeditated, IMHO, still guilty. Just trying to come up with a scenario that might make sense. Either way, not an accident. You have to have a license to have a dog, cut someone's hair for money, go fishing, but no license to have a kid. Just prove to the hospital taking newborn home that you have a carseat. Crazy world.
