Nanny not acting alone in murder in Moscow?

The nanny accused of killing and decapitating a 4-year-old girl in Moscow was not acting on her own, Russian prosecutors told the court Wednesday.
The 38-year-old woman was reported wandering for as much as an hour near a Moscow subway station on Monday holding the head high in the air and yelling things like I am a terrorist — The horrific scene that seems truly insane was not on Russian state television but had extensive internet coverage. It is not clear why it took the police so long to take her into custody.

Before a Moscow court approved Gulchekhra Bobokulova’s arrest , prosecutors told the court they believe there are individuals who “incited” her to carry out the slaying and they are still at large.
Investigators, however, said earlier that the suspect, who is married, appeared to be mentally unstable.

The child’s parents are reported to be a normal middle-class couple.

Lets hope she was acting alone and this is not the beginning of a new type of terrorist attack using mentally unstable people. Already some of the attacks in the US seem insane.
