He is also eligible for parole at some point.

Miller v. Alabama, 567 U.S. 460 (2012), was a United States Supreme Court case in which the Court held that mandatory sentences of life without the possibility of parole are unconstitutional for juvenile offenders.

From what I recall, it's only mandatory sentences of life without parole for minors. Judges can still give a 17-year-old murderer life without parole, there just can't be a state law that forces them to do so. The judge is supposed to consider the circumstances and put thought into whether the offender can be rehabilitated.

Though this guy didn't just murder one person, he murdered ten. So he's getting life regardless, because even if the judge were to give him only twenty years per dead victim, that'd still be 200 years.
