I'm certainly not gonna lose any sleep over junior perp's premature demise, but as for, "he was just about to turn his life around," well, it does happen. My father's a perfect example. Oldest of 9 kids, and poor like most of us have never experienced, he and another guy started committing armed robberies on mom&pop gas stations when they were 16 years old. Got caught of course. My dad was fortunate to be sent to the "boys' town" jail instead of real jail, but the experience straightened him out somewhat I guess, and my mom took care of the rest. Raised two Eagle scouts.
Might be the exception, but it does happen.
