I hope the smirking picture was an old one though (not from after he ran a bicyclist over).

Also, I wonder what the chances are that he waited till he sobered up to turn himself in.

Hit and run is a felony, especially failure to stop and render aid, while DWI is often still a misdemeanor. Not saying the dude was necessarily knowledgeable about that or weighing those options if he was intoxicated at the time.

One of the posters also claims to have met the suspect and attributes the "smirk" to some sort of skeleto-muscular deformity, though it's hard to determine validity with anonymous internet posters.

In most places in the US, a DUI is a felony if someone is injured.

He'd be charged with manslaughter probably.
