A nanny detained by police while holding the severed head of a 4-year-old girl is to undergo a psychological evaluation as part of the murder investigation, Russia's federal Investigative Committee said Thursday.
"The suspect is now under arrest. Very soon she will face criminal charges and undergo a psychological examination in compliance with the Code of Criminal Procedure," spokesman Vladimir Markin told state news agency TASS.
The woman, 38-year-old Gulchehra Bobokulova from Muslim-majority Uzbekistan, is believed to have long suffered from schizophrenia, TASS reported.
She has given the authorities various reasons for killing the child, including that "Allah commanded" her to do it.
In a video that has gone viral on the Internet, Bobokulova confesses to killing the child as revenge for Russian President Vladimir Putin "spilling blood" of Muslims in Syria.
Markin suggested that Bobokulova committed the crime while experiencing an acute bout of schizophrenia.
"Someone with long-standing schizophrenia often commits the crime for reasons that differ greatly from the explanations offered later," Markin told TASS.
"Such people commit crimes while experiencing an acute exacerbation of the disease but explain their actions while in remission. They can be heard offering the most incredible, weird motives," he said.
Bobokulova was caught waving around the child's severed head on Monday near a metro station in north-west Moscow.
Clad in a black burka, the woman yelled "Allahu Akbar" ("Allah is great") before being captured by police.
Authorities found the rest of the child's body in the family's burned-out apartment after extinguishing a blaze that Bobokulova is believed to have started.
Muscovites have been laying flowers and children's toys outside the metro station October Field, where Bobokulova was detained.
