Get tired of seeing this kind of stuff. Like usual, money talks. Yes he was too young but now he should face justice if he did it and if the father is alive he also should be held accountable. ( I haven't followed it and don't know if he is alive.)
I suggest you watch the program. The Boulder police department just wanted to pin it on the family and tried everything they could to do so. Then when they couldn't get it done they looked stupid. They spent all this time trying to frame the family when they could have spent it finding the real killer.
