That is horrible!!! If the police came they will probably get the child protective services out there themselves, wouldn't they?
It reminds me of what happened when I lived in Cicero. The people next door had to many kids to count, and the youngest was about 2 years old. Well as some kids do, this little one screamed all of the time.
One morning I was in my basement doing my laundry, and the police knocked on my door. They wanted to know if I heard a child screaming, well, of course I did. I heard it every day.
Turns out that the parents were "busy" in the bedroom, and one of the father's friends got mad at the little one because she spilled his beer, so he took off his belt, dangled her by one arm and was beating her!!!!!! The people across the street saw it and called the police. I was horrified!!!! Before the police could do much of anything, (they did at least arrest the guy who was beating the little gir) they vanished overnight. I don't think they were in the country legally. It has always and still does bother me that those people have children. And they ran so they went somewhere else where they could continue to neglect those poor kids.
