Samuel Sheinbein. He was prosecuted in Israel, where sentencing is far more lenient, and serving 24 years. Too little time, also the longest sentence issued to a minor in Israel's history. The issue there was a combination of the death penalty and life imprisonment for a minor. Numerous nations, most of Europe and particularly Mexico, where over 350 murders reside, won't extradite to the US for capital offences. Israel did change their immigration laws after that case, and it's unlikely it would could be repeated.
I know the two men who killed him were convicted and I think serving life. However,they found Namblia? material in one of the perps car and the parents were suing Namblia?,claiming that the material triggered the attack. The court hassling was still going on last I heard. I was hoping the parents might prevail. Think I will go Google it.
