Maybe the boy has always been messed up, but going by the article, something happened two years ago, that set him off with all this anti-social behavior. I would not want him around my other kids, if there are any younger ones still at home. They would be directly influenced by him or more likely, harrassed. Something happened, but it’s too late now.
A fall like that could have killed an elderly person.
Drug-test the kid....I’ll guarantee you that he fails.
