I've been trying to think of the nicest way to say this, but Jalen Carter might have just gotten into more trouble than we realize. If he was at the scene, he had to have seen how bad that wreck was. He left without even calling 911 to get assistance on the way. This could possibly put him into further legal peril. In some states, leaving the scene of a crash you were involved in without rendering aid or calling 911 can get manslaughter added to the list of crimes you are indicted for. So far he has misdemeanors he has been charged with. I can easily see felony charges forthcoming once they get all the info together.
Oddly, I could see him walking away with community service because he'll "just" get misdemeanor charges.
I could also see the scenario playing out as you describe.
I remember a young girl causing and leaving the scene of an accident years ago. She painted the car to try and avoid getting caught. She ended up getting the manslaughter charges you described and is now in jail, last I remember. I don't think the Carter kid went to those lengths, but he was certainly evasive.
I wonder if the Athens police will have the guys to follow the evidence or of they'll take the easy way out. Seems they were preparing to head down Easy St. before the ajc forced their hands.
