Oh gosh... I hope she finds them safe and sound. Sounds like the woman who moved out had a child with some major emotional issues going on. Kids like that, who kills small animals and things like that for fun have some MAJOR issues going on (usually sexually abused etc... we get that at school a lot). They turn out to be not very nice adults if they are not gotten help. It's sick how some people prey on the vulnerability of defenseless animals.
