She admitted that her stepson had become fascinated by Satanism – and was obsessed with Onegina who also had friends interested in the occult.
In testimony to police when she was initially detained, Onegina said she had 'accidentally strangled him during hard sex'.
She claimed to have hacked his body up so she was not blamed for murdering him.
Later, she said she had no memory of the killing or dismembering.
