In March 2005, the United States Supreme Court ruled that the death penalty for those who had committed their crimes at under 18 years of age was cruel and unusual punishment and hence barred by the Constitution. On March 1, 2005, Roper v. Simmons, 543 U.S. 551 (U.S. 2005), the U.S. Supreme Court abolished the death penalty for minors. Prior to this ruling, minors were subject to the death penalty in a majority of states where the death penalty was practiced.
Minors committing serious crimes (murder, aggravated assault, etc.) can be tried as adults. The minimum age at which someone can be tried as an adult varies by state. As Rotten pointed out, the Supreme Court ruled that sentencing minors to death is cruel and unusual punishment but it is still legal to sentence children as young as 13 to spend the rest of their life in prison.
The USA can not execute a minor until they reach the age of 18 which is not considered a minor.
Oh, and the site also says that there was a 16 year old boy executed in Oklahoma in 1999.
Minors don't get punished that harshly for committing crimes
