In November 1999, fourteen-year-old Kuntrell Jackson and two other boys decided to rob a video store in Arkansas.
En route, Jackson learned that one of the boys carried a sawed-off shotgun. Jackson initially stayed outside the store but later entered while the robbery was underway. When the clerk, Laurie Troup, refused to hand over money and threatened to call the police, one of Jackson's co-defendants shot and killed her. The three boys fled without taking any money.
Arkansas prosecutors exercised their discretion to charge Jackson as an adult with capital felony murder and aggravated robbery. A jury convicted him of both offenses. The trial court imposed the statutorily mandated sentence of life imprisonment without the possibility of parole. Jackson did not challenge the sentence on direct appeal, and the Arkansas Supreme Court affirmed the convictions.
In 2003, fourteen-year-old Evan Miller and a friend, Colby Smith, spent an evening drinking alcohol and smoking marijuana with Miller's neighbor, Cole Cannon, at Cannon's trailer in Alabama. After Cannon passed out, Miller stole his wallet. Cannon awoke and grabbed Miller by the throat. Smith struck Cannon with a baseball bat, and Miller then repeatedly hit Cannon with the bat. The boys set two fires in the trailer before leaving. Cannon died from his injuries and smoke inhalation. Miller had previously been in and out of foster care, regularly used drugs and alcohol, and had attempted suicide four times.
Alabama law initially required that Miller be charged as a juvenile, but the district attorney sought and obtained removal of the case to adult court. A jury convicted Miller of murder in the course of arson. The trial court imposed the statutorily mandated sentence of life imprisonment without the possibility of parole. The Alabama Court of Criminal Appeals affirmed the conviction and sentence.
Following this Court's decisions in Roper v. Simmons and Graham v. Florida, Jackson filed a state habeas petition arguing that his mandatory life-without-parole sentence violated the Eighth Amendment. The circuit court dismissed the petition, and the Arkansas Supreme Court affirmed. Miller's direct appeal was likewise unsuccessful. The Supreme Court granted certiorari in both cases.
