Valdo Calocane killed three people – history student Barnaby Webber, aspiring medic Grace O'Malley-Kumar, both 19, and caretaker Ian Coates, 65 – in devastating knife attacks in Nottingham in June 2023. He then stole Mr Coates’ van and ploughed into three other people – Wayne Birkett, Sharon Miller, and Marcin Gawronski – leaving them seriously injured. Three years on from the horrific attacks, a public inquiry is examining the failings that may have prevented that fateful day. The triple killer’s mother and brother tell Rebecca Thomas how they are urging politicians to look at the ‘systemic failings’ in mental health care – warning that the ‘decimation’ of funding for services is destroying lives.
