15 yo kid? Yeah, he's fucked.
And when his fellow inmates find out what he's in for, he's even more fucked... And not in a fun, prison-fantasy sorta way.
Bleeding hearts can lament all they want about what could have been, but the bottom line is that he made very specific, very illegal choices and (thankfully) got caught.
The silver lining, if any, is that the people who helped him cover this up for many years will hopefully change their ways or face the same fate. I'm sure a lot of his close associates are still under some form of investigation.
