charged with two counts of murder and three counts of child abuse
That doesn't make sense. The charge for killing a child is "child abuse," not murder? Maybe it's the way the statutes are written or something, or maybe the state believes if you kill a kid it's a cinch to prove the elements of abuse. Yes, I would agree that killing a child is pretty abusive.
Maybe he did something to the kids before he killed them. Maybe they charged him with child abuse for making them watch him kill their parents. It’s all nuts because the shooter was 15 and most likely will not be tried as an adult. If you notice there is no mention of ethnicity of either the victims or the perp.
There are more up to date accounts of this story. The teenager is named Nehemiah Griego. He is one of ten children. He killed his parents and three of his siblings. His father was a pastor.
