Oleg Belov, the man accused of slaughtering his six children, pregnant wife and elderly mother, was declared sane on Wednesday and therefore eligible to face criminal charges, the Investigative Committee said Wednesday in an online statement.
"During the course of the investigation, the accused underwent a psychiatric evaluation that determined he is suffering from a psychiatric condition that does not mean he is not not responsible for his actions. He is therefore subject to criminal prosecution," the statement read.
Belov, 51, was arrested in August several hours after the dismembered remains of his six children and pregnant wife were found in the family's apartment in Nizhny Novgorod and his mother's corpse was discovered in a hole in the yard of her dacha in the neighboring Vladimir region.
He was earlier reported to have been diagnosed with schizophrenia.
