I disagree. He turned himself in. MOST people who shoot someone, or involved in an incident where someone dies DO NOT turn themselves in. Hence we have America's Most Wanted and people who sometimes go decades without facing their punishment. How many adults plead guilty and admit their crimes in court? It's always, it wasn't me, I was set up, I never saw that person before ... or covering up evidence, hiding the body, killing or threatening witnesses about coming forward. It takes guts to admit when you make a mistake. Watch Cops, Jail, Gangland, Dark Justice, 48 hours, Dateline or any of the hundreds of these shows and see for yourself how uncommon it is that someone step up and take responcibility for their actions and turn themselves in. 

So again, kudos to this young man for stepping up and doing the right thing. Stayed with his friend, confessed and turned himself in.
