I did some sleuthing..
"The penalty for leaving the scene of an accident in Michigan is a felony punishable by up to 5 years in prison and a $5,000 fine or both if serious impairment of body function or death occurs. If the fleeing driver was at-fault, then the fine could be $10,000 and the prison term could be 15 years. (MCL 257.617(2) and (3))"
The above charges don't include the ' 'fleeing overseas' charge which I believe is quite serious
