I’ve always found the parents very hard to believe. Who the hell leaves a child that young alone to go out partying?
Drug addicts and worse, imho.
I’m on the fence with the parents. On one hand, how could the parents be so stupid but on the other hand European parents are more trusting with their children. They’ll leave them in baby buggies outside shops and let them take public transportation at young ages. On a third hand, they may have killed her and later dumped her body. Add another hand and they may be involved in sicko child sex.
