Carl Cooper had a known history of domestic violence and had previously stood trial for attempted murder in 1999, but was acquitted due to lack of evidence.

Naomi Hunte reported Cooper to police four times in 2020–2021, describing stalking, harassment, and intimidation.

On 14 February 2022, Naomi was found stabbed in the chest in her Plumstead flat; a blood-covered steak knife was found nearby.

Cooper was arrested but released under investigation due to lack of immediate forensic evidence.

Fiona Holm, who had autism and a learning disability, began a relationship with Cooper in late 2022.

In April 2023, Fiona reported Cooper to police for attacking her with a crowbar and previously stabbing her with a screwdriver – but again, no charges were brought.

Cooper was given a 28-day Domestic Harm Prevention Order – it expired on the day Fiona was last seen, 20 June 2023.

Fiona was last seen on CCTV buying alcohol in Catford; she never returned home and her fridge was later found full of rotting food, laundry left in the machine – totally out of character.

Fiona’s daughter and sister led the search themselves, eventually spotting Cooper in his flat through a scraped-off windowpane.

Police only arrested Cooper after the family caught him selling Fiona’s coats in the street – one of which still smelled of her.

Forensic analysis of Cooper’s flat found Fiona’s blood on the walls, doors, and even the Wi-Fi router – despite his attempt to repaint and redecorate.

The police had not linked the two cases until both were presented together in court in 2024.

Cooper was found guilty of both murders in June 2024 and sentenced to life with a minimum term of 35 years.

Fiona’s body has never been found.

Four Met Police officers are under investigation for misconduct due to failures in safeguarding and response to both victims’ earlier reports.
