Petrit himself says he was walking.
Him saying that throws out the car surfing scenario. That is, if it was his true memory or if someone else told him that as he may have had amnesia that extended to a little while before whatever happened, happened. Further, 'car surfing' involves either being up on the roof or sitting on the front end of a car. He wouldn't of fallen out, he would have fallen off. I think a broken bone or two would have occur if that was the case.
He says he has some 'scars that are consistent with being hit by a car.' I bet they are 'road rash scars'. The scars thing throws out the beat down by random peeps. Punching leaves bruises, which fade away.
I haven't tried to look up articles about it, but when I read the lifelong scars bit, it made me think he may have been hit 'head on' sort of, and fell and hit his head hard causing the coma inducing head injury but then, I think he might have been DRAGGED along with the car for a bit, hence 'road rash' scars.
I don't know if any of you have driven over anything that dragged along the undercarriage of the car (it wasn't a body, I swear!) but the sound it makes is really unnerving, especially if it happens on a road where there shouldn't be anything to hit. The vast majority of people would get out to check and see what they hit as well.
If *I* had hit a body, I would most likely be in a zombie like state, alcohol or not (can't remember if it's thought she was drunk). I've read here periodically, and it sounds like Maura had problems with getting into accidents. After all those, and then hitting a person.. I would be insane with fear of prison for life etc, even though the average sentence for vehicular homicide h&r is only about 4 years. Whoever hit him could have easily thought him to be dead for sure.
So, I disagree w/ Mr. Vasi for the above stated reasons.
