Repeated failures in Essex Police's handling of reports of abuse were highlighted by the Independent Police Complaints Commission (IPCC) following the cases of:
- Maria Stubbings, a 50-year-old mother of two from Chelmsford, was strangled with a dog lead in 2008 by Chivers who also killed a previous girlfriend.
- The IPCC found there was no assessment of the risk Chivers posed to Ms Stubbings and as a result she was not afforded proper protection.
- Christine Chambers, 38, from Braintree, who was shot dead in 2011, along with her daughter Shania, by her ex-partner David Oakes.
- Ms Chambers had been complaining about violence from Oakes for two years before the murders. The IPCC found the force's response was "inadequate".
- Jeanette Goodwin, 47, was stabbed 30 times by Martin Bunch, 44, in 2011, in front of her husband at her home in Southend, Essex.
- The IPCC found she received an "inadequate response" from Essex Police on the day of her murder, adding that the force did not recognise the need for urgent action.
