The mother of the man who killed three people in an attack in Nottingham in 2023 has told an inquiry that the mental health “system is broken” and until there is a crisis “no one listens to you”.

Valdo Calocane, who has paranoid schizophrenia, was sentenced to a suspended hospital order in January 2024 after killing students Barnaby Webber and Grace O’Malley-Kumar, both 19, and Ian Coates, a 65-year-old caretaker, on 13 June 2023, and attempting to kill three others.

Calocane’s mother, Celeste, gave evidence for the first time at the inquiry into the attacks, which is looking at what happened in the lead-up and after the incident. Calocane was sectioned four times between 2020 and 2023. During this period, Celeste Calocane described repeatedly “raising flags” to medical staff but said “no one was acting on it”.

The counsel to the inquiry, Rachel Langdale KC, said notes from May 2020 showed Ms Calocane had warned of her son’s “risk to others in his current mental state”, after he had attempted to break into a neighbour’s flat. Calocane was later admitted into hospital.

During the first hospital admission, Ms Calocane’s other son, Elias, compiled a dossier of information and sent it to Calocane’s doctor. The document included violent and paranoid messages Calocane had sent to him, including one where he said he was “thinking about red rum”, which is murder spelled backwards. In another, Calocane told his brother he wanted to “hurt permanently”.

Calocane’s mother, who said she did not look at the document at the time, said doctors had not responded to the dossier so she thought it was not “useful” to them. She said she wanted Calocane to be diagnosed but doctors advised against it, and instead said Calocane was suffering with a “psychotic picture”. Calocane was discharged from hospital on 13 June 2020, against his mother’s wishes.

One month later, Celeste Calocane contacted her son’s crisis team to alert them to concerns for his mental state. Two days later, Calocane tried to break into a neighbour’s flat again and was sectioned for a second time. She said: “I [knew] something wasn’t right because of our conversation. So I phoned the services and they just didn’t do anything about it until he was in crisis.”

The inquiry was previously told that, during Calocane’s second hospital admission, a doctor had said Calocane could “end up killing someone” and his diagnosis was “likely schizophrenia”. Ms Calocane told the inquiry that she was not informed of this at the time.

She said she had hoped her son would be kept in hospital for at least six months but he was discharged after two weeks. She also told the inquiry that, in August 2020, she warned of Calocane’s “risk to others”.

Asked if anyone discussed her son’s risk with her, Ms Calocane said: “Never. I just had to navigate the system myself and try to make sense of what was going on.”

She added: “I was doing a mental health job for them, even though I wasn’t trained, I was the one raising the flags … no one was acting on it, until I said something”.

Ms Calocane also told the inquiry on several occasions she was denied information from medical professionals because Calocane had instructed staff not to share any details.

She was also challenged on why she did not leave work on the morning of 13 June 2023, when Elias had told her about a call he had received from Calocane.

The inquiry heard Calocane told Elias in the call it would be the last time he would hear from him and, when asked if he would do something stupid, Calocane said it was “already done”. Ms Calocane told the inquiry that she feared her son had attempted to kill himself.

However, at this point, Calocane had killed Webber and O’Malley-Kumar.

Challenged on why she did not leave work, Celeste Calocane said: “Looking back, maybe that’s what I should have done, but I didn’t do that because this is something I’ve been living with for the last three years.”

The inquiry continues.
