People v. Lewis

Did Montgomery v. Louisiana clarify that Miller v. Alabama created a presumption against a sentence of life imprisonment without possibility of parole for juvenile offenders and requires trial courts to determine that a juvenile offender is one of "those rare children whose crimes reflect irreparable corruption" before imposing such a sentence? Or is it sufficient, for purposes of compliance with Montgomery and Miller, that a trial court take into consideration the offender's youth and attendant circumstances in exercising its sentencing discretion under Penal Code section 190.5(b)?
