Nottingham Stabbing Inquiry Finds Barnaby Webber’s Death Potentially Preventable Amid Systemic Failures

Core Event: June 13, 2023 Stabbings and Fatalities
On June 13, 2023, Valdo Calocane stabbed three people in Nottingham—19-year-old students Barnaby Webber and Grace O’Malley-Kumar, and 65-year-old caretaker Ian Coates. All died from their injuries.
Background & Context: Calocane’s Mental-Health History and Prior Interactions
Calocane was diagnosed with paranoid schizophrenia in 2020 and was sectioned four times between 2020 and 2022. He faced an arrest warrant for failing to appear on an alleged assault of a police officer. He was evicted from his Burford Road flat on June 11, 2023, travelled to London, and returned to Nottingham shortly before midnight on June 12, 2023.
Evidence of Undisclosed Documents
Police recovered a holdall bag and a bin of notebooks from Calocane’s former address. The notebooks listed “thoughts” such as explosives (TNT, nitrate fertiliser) and self-descriptions of being “a God.” These materials were not disclosed to the Crown Prosecution Service, psychiatric experts, or the inquiry until June 2024.
Medical Assessment of Survivability
A panel of emergency-medicine experts reviewed the night-time response. They concluded that Barnaby Webber had “far less than 50 %” chance of survival and that his death was “potentially preventable” if volume resuscitation and blood products had been administered more aggressively at the scene, followed by rapid transfer to intensive care. The panel judged the deaths of Grace O’Malley-Kumar and Ian Coates “not preventable” given the severity of their injuries.
Official Statements & Responses
Rachel Langdale KC, counsel to the inquiry, called the omission of the notebooks an “oversight by Nottinghamshire Police” and urged full disclosure. Senior judge Deborah Taylor KC described the emergence of hidden material as “disappointing” and ordered core participants to submit any corrections or omissions by December 31.
Adam Straw KC, representing Calocane’s family, highlighted chronic under-resourcing of mental-health services and called for national staffing guidelines and increased funding, arguing that proper treatment in May 2020 might have averted the tragedy.
Conflicting Reports & Gaps
Professor Nigel Blackwood, who assessed Calocane at his trial, said the newly disclosed notebook material did not fundamentally alter his understanding of Calocane’s mental disorder. Families argue the notes, including references to large venues and explosives, indicate a missed investigative opportunity that could have informed risk assessments. The inquiry has not resolved this discrepancy.
Verbatim Quotes
- “Nobody has ever asked [Calocane] why he was researching explosives and large venues, because they couldn’t,” — Maloney
- “Too often these cases are dependent upon bereaved families campaigning at a time when they are least prepared to do so, and it is an outstanding public service that they perform.” — Rachel Langdale
- “There was a failure to investigate VC's historical behaviour and actions,” — Tim Moloney
- “Over the break since we were last here, some evidence has emerged which ought to have been identified by core participants and disclosed earlier.” — Deborah Taylor, senior judge
What’s Next
The inquiry chair has directed all participants to provide any further corrections by December 31. A comprehensive report is slated for publication early next summer, with interim recommendations on emergency-response protocols and mental-health service funding.
