Last year, the U.S. Supreme Court ruled in Miller v. Alabama that mandatory life sentences for offenders under 18 are cruel and unusual punishment, and therefore unconstitutional. In the wake of that decision, a federal court this month ruled that Hill and more than 300 other Michigan juvenile lifers are entitled to a parole hearing.
Michigan is one of at least 11 states that have revisited their sentencing laws in response to the Supreme Court decision (see Stateline chart). Generally, juvenile killers in those states will be eligible for a parole hearing after serving a mandatory minimum sentence of about 25 years.
Still, there are at least 15 states that have not yet eliminated mandatory life without parole sentences for juveniles. In many states, legislatures and courts aren't sure how the Miller decision should apply to offenders such as Hill who are already serving such sentences. Nationwide, there are more than 2,000 prisoners in 43 states serving life without parole sentences for crimes they committed as juveniles.
