A police force is facing legal action after failing to protect a woman from her ex-boyfriend, despite officers knowing he'd killed before.
Her family say Maria Stubbings would still be alive today if the police had done their jobs properly.
Maria's son Bengee has been speaking to Nick Thatcher, about his memories of his mother.
The son of a woman murdered by her ex-boyfriend has spoken of his shock at finding out that a man he called his 'friend' had killed her.
Maria Stubbings from Chelmsford was murdered by Marc Chivers, who had recently been jailed for assaulting her.
An IPCC investigation found that Essex Police had removed a panic alarm from her home, despite knowing that Chivers had killed a previous girlfriend. Maria's son, Bengi Stubbings, who was 15 at the time, was left with Chivers in the house, not knowing that his mother's body was hidden there.
Chief Constable Stephen Kavanagh of Essex Police said: "I recognise the pain that the Stubbings family are going through but I am absolutely committed to say we are doing things differently to 2008, differently to 2011. But there is a lot more that we need to do."
