The life sentence for Nicola Edgington, 32, came on the day that the Independent Police Complaints Commission found failings in the murder case:
- Local police in Greenwich were not notified that Edgington was living in the area.
- Police and police staff did not carry out a police national computer check on Edgington which would have alerted them to her previous conviction for manslaughter.
- Officers missed an opportunity to use their powers under the Mental Health Act when Edgington tried to leave an A&E department shortly after she arrived with police.
- Edgington's second 999 call from an A&E department was downgraded because she was considered to be in a place of safety and an officer was not asked to return despite Edgington saying she could be very dangerous.
- The police only contacted the hospital after a fourth call had been received.
