Evan Miller was 14 years old on the night of July 15, 2003, in Moulton, Alabama. By that age he had attempted suicide four times, the first at age six. He had been in and out of foster care because his stepfather beat him and his mother abused drugs and alcohol. That night, he and his friend Colby Smith were drinking heavily with their neighbor Cole Cannon, who was 52. When Cannon passed out drunk, the two tried to rob him of his baseball card collection. Cannon awoke. Miller beat him repeatedly with a baseball bat. The two then set fire to Cannon's trailer and left. Cannon died of blunt force injuries and smoke inhalation. Miller was tried as an adult, convicted of murder in the course of arson, and sentenced to mandatory life without parole. Alabama's statute gave the judge no choice.
Kuntrell Jackson was also 14 in November 1999 in Arkansas, when he and two older companions planned to rob a video store. Jackson learned on the way there that one companion was carrying a sawed-off shotgun, but he proceeded. When the store clerk, Laurie Troup, refused to hand over money and threatened to call the police, the companion with the gun shot and killed her. Jackson did not fire the shot. He was convicted of felony murder, which allows a death that occurs during a felony to be attributed to all participants regardless of who pulled the trigger. Jackson was also sentenced to mandatory life without parole.
Both defendants appealed. The central question was whether the Eighth Amendment permits a sentencing statute that requires life without parole for every juvenile convicted of a qualifying homicide offense, without allowing the sentencer to consider the offender's age, background, level of participation, or any other circumstances.
