Colin Norris Wiki
Colin Norris Biography
Colin Norris, 45, nicknamed the ‘angel of death’, was convicted in 2008 by a majority of murdering patients by injecting them with lethal doses of insulin at Leeds General Infirmary and the city’s St James Hospital.
The four women who died (Ethel Hall, Bridget Bourke, Doris Ludlam and Irene Crookes) and the fifth woman, Vera Wilby, were elderly patients hospitalized in orthopedic wards in Leeds, where she worked as a nurse.
However, the Commission for the Review of Criminal Cases (CCRC) has now decided to refer the five convictions to the Court of Appeal after new expert evidence presented by the representatives of Mr. Norris.
In a statement, the commission said: ‘The CCRC considered new expert evidence submitted by Mr. Norris’s representatives and ordered its own expert to provide a series of reports.
‘This new expert evidence explored recent developments in a complex area where scientific understanding is still developing.
Norris – who was born in Glasgow – was found guilty of four counts of murder
The prosecution said all the women died from hypoglycemia, an extremely low level of sugar in the blood, which causes the brain and other important organs to stop working.
The nurse was jailed for the murder of Irene Crooks and Ethel Hall.
This condition was claimed to be caused by insulin injections and Norris was sentenced to life in prison with a minimum period of 30 years.
The case against him was entirely circumstantial and relied heavily on evidence from expert opinion on a number of complex medical and scientific issues.
Experts have now agreed that hypoglycemia in four of the women, in addition to Ms. Hall, may be due to natural causes, according to the CCRC.
Mrs Hall developed severe hypoglycaemia while in hospital and died on December 11 2002 and the cause of her murder is not being questioned.
However, the CCRC believes that this conviction depends on the support of the other four cases and the prosecution’s assertion that no one other than Norris could have been responsible.
The CCRC said the new evidence also highlighted several other relevant developments in understanding hypoglycemia, including its prevalence in the elderly and frail.
This has cast further doubt on the expert opinion on which the prosecution relied at trial.
The statement added: ‘The CCRC considers this conviction to depend on the support of the other four cases and the prosecution’s claim that no one other than Mr. Norris could have been responsible.
“In light of the new expert evidence, the CCRC is convinced that this claim is now less certain and that, as a result, there is a real possibility that the Court of Appeal will also overturn this conviction.”
