(AP Photo/Alexander Zemlianichenko) (Newser) – A grisly crime out of Moscow: Police on Monday arrested a woman who was seen waving the severed head of a small child outside a subway station, reports AP. She is suspected of killing the child when it was in her care, officials said. Videos posted on Russian news websites show a woman dressed all in black, holding the severed head and shouting, "I am a terrorist" in Russian, although most of what she says is incomprehensible. In some of the videos, the woman is tackled by men who appear to be police. "According to preliminary information, the child's nanny, a citizen of one of the Central Asian states born in 1977, waited for the parents and elder child to leave the flat and then, for reasons not established, murdered the infant, set fire to the flat, and left the scene," says a statement from Moscow authorities cited by the BBC. The 38-year-old woman was undergoing a psychiatric evaluation as police search for a motive. The victim was 3 or 4 years old.
