Calocane stabbed Barnaby Webber, Grace O'Malley-Kumar and Ian Coates to death before trying to kill three others on 13 June 2023. Retired senior judge Deborah Taylor KC is chairing the inquiry, which is hearing from more than 100 witnesses over a total of nine weeks. " Earlier the inquiry was shown office footage of force incident manager, Ch Insp David Mather, being updated on the situation at about 07:00 BST, three hours after the killings began. Sophie Cartwright KC, representing some of the victims, suggested Mather had "no situational awareness" as he did not issue updated briefings about the level of threat as the nature of the attacks became clear and some information about the location of attacks and numbers of victims was missing from other updates. He said there was "no inspired detection" and if Calcocane had tried to flee instead of continue attacks, he could have been "long gone". uk or via WhatsApp on 0808 100 2210.
