Guys before you wish bad on someone else ask yourself if you are perfect; have you made blunders in your life which just so happen that it didn't come out, or it came out and you or your family were able to supress it with money or influence. People make mistakes and they face due consequene of their action; that's what laws are there for.
I understand emotions run high in the incidents like these, yet when you wish bad or evil on others you let evil lead you in turn. Don't spread negative energy, rather wish that the young man changes for good dispite his grave mistake; if you can then pray for him and his family so that something good comes out of the bad circumstance.
