Nicola Edgington jailed for 37 years for street decapitation, as report blames police blunders for attack Nicola Edgington, 32, was found guilty last month of murdering grandmother Sally Hodkin, 58, and attempting to murder Kerry Clark, 22, in Bexleyheath, south-east London, in 2011. She also killed her mother in 2006. Hours before the attacks, Edgington sought help at a local hospital from where she called 999. But after delays in admitting her, she walked out and took a knife from a butchers shop before the attacks . The 2011 killing came after Edgington was released back into the community in 2009. John Cooper, QC, mitigating, said she was a woman in crisis and had not been given the help she asked for. But the Recorder of London Judge Brian Barker said Edgington should stop blaming others for her actions and take responsibility. He jailed her for life with a minimum term of 37 years for murder and gave her a concurrent sentence of life with a minimum term of 20 years for attempted murder. Judge Barker told Edgington, 32, her behaviour had been "consistent and calculated." He said: "You are manipulative and exceptionally dangerous. What you did could not have been more selfish. I disagree that the responsibility for these acts can be laid on others. You made your choice and these were terrible acts for which you must take responsibility. You have come as near as can be to having three deaths on your hands. Miss Clark had escaped only with cuts to her hands because of her bravery and quick action, he said. Meanwhile an Independent Police Complaints Commission (IPCC) report revealed police failed to carry out adequate checks into Edgington. She made five 999 calls on the day of the attack asking to be sectioned under the Mental Health Act because she believed herself to be a danger but hours later she was still at large, the report said. The investigation found local police in Greenwich were not notified that she was living in the area after an order for her indefinite detention was lifted.
