Police removed 10 children and teenagers Tuesday night who had been in the care of Linda Ann Weston, the woman charged this week with enslaving four mentally challenged adults in a Tacony basement, and said the group showed signs of abuse and malnutrition.
Among the group was Beatrice Weston, 19, a niece reported missing in 2009.
Investigators are trying to find the parents of the children, and police said two of the children may be related to one of the adult victims kept in the basement. Others may have been kidnapped.
"This is a very complicated case," Police Commissioner Charles H. Ramsey said Tuesday night. "This is a very sad story. It makes no sense. When you look at the kids, the psychological trauma is pretty apparent. It's some of the worst things I've ever experienced."
