The U.S. Supreme Court says it's unconstitutional to sentence juveniles to life in prison without parole for murder.

The high court on Monday threw out Americans' ability to send children to prison for the rest of their lives with no chance of ever getting out. The 5-4 decision is in line with others the court has made, including ruling out the death penalty for juveniles and life without parole for young people whose crimes did not involve killing.

The decision came in the robbery and murder cases of Evan Miller and Kuntrell Jackson, who were 14 when they were convicted.

Miller was convicted of killing a man in Alabama. Jackson was convicted of being an accomplice in an Arkansas robbery that ended in murder.
