He hasnt actually been charged yet so I'll hold off complete judgement until that happens. His background shows that it is highly likely that he was probably intoxicated at the time of the injury.
Its one of the things I always mention to people and preach to my friends that still drink and drive. When i got my DUI, i was in a multicar wreck (that wasnt my fault, i was collateral damage in it, just happened to have "2-3" beers in me. There was a baby involved in the accident. Had that baby died I'm sure I'd been paying lawyers fees out the ass to avoid massive jail time because they would've tried to pen it on the person under the influence. Most people leaving the bar, all they think about is "i hope i dont get pulled over or come up to a traffic stop" I tell the guys, That could be one of the better outcomes, u get in a wreck and someone in the other vehicle dies, thats on you for life, both in prison and in your head. one of my 2nd cousins spent about 3 or 4 years locked up because an old couple ran a stop light, hit him, and the old man died. They ran the light but said that "had he not have been drinking, he probably would've been more aware that the old couple were getting ready to run a stop light, heres your hand cuffs.
