Daniel Coriat had a long history of paranoid schizophrenia, diagnosed in 2005, and was well known to mental health services.

He had been sectioned under the Mental Health Act, treated as both an inpatient and outpatient, but frequently disengaged from treatment and stopped taking medication.

Despite showing signs of deterioration and making repeated paranoid statements about his mother, including calling her a witch, he was deemed low risk and discharged without safeguarding measures in place.

Elizabeth, who had been Daniel’s sole carer, had expressed fear and concern to professionals about his worsening condition in the weeks before her death.

In August 2012, Daniel killed Elizabeth in their flat — she was found stabbed and decapitated, her head placed beside her body.

Daniel fled the scene and was later found naked and covered in blood, hiding in a wheelie bin near Honor Oak Park station, acting incoherently.

He was deemed unfit to stand trial and was detained indefinitely under Sections 37 and 41 of the Mental Health Act, meaning he can only be released with the approval of the Secretary of State for Justice.

There was no formal inquiry into Elizabeth’s death, despite clear systemic failings in community mental health care and risk management.

Her case is now cited in discussions around the Femicide Census, which documents how many women – particularly mothers – are killed by men known to services, often after multiple warnings are ignored.
