Overview

• Colin Campbell, convicted in 2008 of murdering four elderly patients via insulin injections, has launched an appeal at the Court of Appeal in London.
• The Criminal Cases Review Commission referred the case, citing new expert evidence and evolving medical understanding of hypoglycemia as grounds for reconsideration.
• Defense lawyer Michael Mansfield KC argues that recent findings suggest the patients may have died from natural causes, challenging the circumstantial nature of the original prosecution.
• Four additional cases of severe hypoglycemia between 2003 and 2005 have been identified; these deaths were attributed to natural causes, raising questions about the uniqueness of the original cluster.
• The appeal, presided over by Lady Justice Macur, Sir Stephen Irwin, and Mr Justice Picken, is expected to last three weeks, with the Crown Prosecution Service opposing Campbell's case.
