We had a kid like this in our neighborhood when I was a child. Totally nuts. Good family, other children were normal. He tortured animals, set fires in the woods and finally tied his little sister to a bed and set it on fire. The parents got to her in time. I’m sure he ended up in prison at the very least.
We had a kid like this in our neighborhood as well. His father was an ex-con, and he (the son) shot at our house when he was in grade school. Eventually, we moved due to unrelated events.
I’d be surprised if he hasn’t been in prison multiple times.
This was a nice neighborhood, too.
