It's plain and simple to me. He told the police he left the cage unlocked.At the time Darell told deputies he put the snake in an unlocked cage the night before, then found the snake in the bed on top of the girl when he woke up, according to authorities.
No matter whether the baby died from the burm or by the guy's hand, it's still HIS FAULT the girl died. I guess the question remains about whether it was manslaughter or murder.
