There is a lesson for this "mother" which does not make her "mom".
Its a little late to be mourning over the LACK of training and raising one up to do right always and to run from doing wrong. Perhaps if she had took to her the wisdom of Solomon and read her Bible about raing kids a little more these kinds of things would happena whole lot less.
Proverbs 22:6 says "Train up a child in the way he should go: and when he is old, he will not depart from it."
Proverbs 13: 24 says "He that spareth his rod hateth his son: but he that loveth him chasteneth him betimes."
There is a direct correlation to lack of parenting and teaching children how to act and right from wrong and criminal kids who think the world is all about them and they are immortal no matter what they do..
This child's death lays at the feet of his parent or parents.. He was a jerk and a dumbass. Now he's dead.
I hope he knew Christ as Savior. Otherwise he is burning in hell right now..
