James Mathurin appealed convictions and a 685-month sentence for armed robberies and carjackings committed when he was a juvenile. He challenged suppression rulings, evidentiary decisions, the denial of a motion to dismiss, and the constitutionality of the sentence under the rule limiting life-without-parole punishment for juvenile nonhomicide offenders. The Eleventh Circuit affirmed. It held that the challenged searches and seizures were lawful, that the evidentiary rulings did not require reversal, and that the evidence supported the convictions. It also held that Mathurin’s lengthy term of years was not equivalent to life without parole under the circumstances and that the sentence did not punish him for exercising appellate rights. The court concluded that the district court had adequately considered the seriousness of the crimes and the need to protect the public. It affirmed the convictions and sentence.
