If a juvenile were to kill anyone, it would depend on whether that state wants to prosecute the offender as a youth or as an adult. If he or she is prosecuted as a youth, in most states, the offender would only serve a sentence until they reached age 21. That is why many states now try juveniles as adults, so they can be given a longer sentence for their crime.
they would be tried as an adult, after a physc evaluation. And more then likely sentenced to the death.
He could be charged as a minor (juvenile) or as an adult for the crime, based on his age and severity of the offense.
One capable of such an act would likely be old enough to be tried as an adult. Even without such trial, an act such as this would now be considered an act of terrorism, which would subject them to military prison without trial.
They would be killed by other means
If a juvenile fails to appear in court, an arrest warrant will be issued. It is also possible that the parents of the juvenile will be notified, fined, and/or charged.
They would be KILLED
