The sister of a young woman who allegedly beheaded their mother in a psychotic episode has broken her silence and revealed her family is 'going through hell'.
Jessica Camilleri, 25, is accused of stabbing her mother Rita Camilleri, 57, to death with multiple kitchen knives in St Clair, western Sydney, on July 21 before cutting off her head and tossing it on to a neighbour's lawn.
With her sister behind bars after being charged with murder, Kristi Torrisi said she struggled to find the words to describe the pain her family is going through.

'My mother and my sister are both gone. We're going through hell,' she told The Daily Telegraph.
'Jess is really, really not well - I can't bring myself to talk about what we're going through.'
It emerged after her mother's death that Jessica had been charged four times with violent assaults but been freed from custody every time under the Mental Health Act.
She was employed at her local Kmart in Mount Druitt as a greeter at the front of the store, but had not turned up at her shifts for a week prior to the alleged attack.
