A friend from high school got in with the wrong crowd and got stabbed numerous times by his psycho ex-girlfriend a few years ago. Don't know if the crazy bitch ever served any time. It's still hard for me when I pass the parking lot where he bled out.
A couple years ago my cousin's kid (who had just started school) was killed by the drug-addicted father. Maybe someday one of his fellow inmates will do society the great service of hacking him to bits as well.
The moral of both stories is that drugs are very, very bad.
