JASON Voong's victims said they have been denied their final piece of closure after a court failed to keep them informed of his sentencing.

The 29-year-old, of Southbrook Street, was detained under an indefinite hospital order today having been convicted of the manslaughter of Aulton 'Tom' Rogers, and wounding with intent of Leanne James.

But Leanne and Tom's family were unable to watch justice being done having been given the wrong time to arrive at court.

Members of Tom's family had travelled from Australia for the trial, and all of the witnesses spent 18 months awaiting the verdict and sentencing after Voong's arrest.

"We arrived only to be told it had already happened," said Leanne. "That's bad enough for me, but Tom's family have come from the other side of the world for this. They are obviously very upset. We have gone through the whole process only to be denied that final bit of closure."

Leanne said they had been given a time to return by the court when the jury delivered their verdict on Monday, but it was moved two hours forward. Voong's family had been kept informed and were present at the sentencing.

"We have been told the CPS were supposed to have informed us, and the worst part is that Jason's family had been told, so they were all there," she said.

An HM Courts and Tribunal Service spokesman said: "We apologise for the distress caused. We are urgently investigating what went wrong in this case and will be contacting those affected."

At the hearing Dr Samrat Sengupta told the court Voong was suffering from an extremely rare form of simple schizophrenia, from which he may never recover.

"This person will need hospital admission and treatment for the foreseeable future," he said. "It would be very dangerous to release this man into the community without adequate treatment, assuming he could be safely released.

"The type of schizophrenia he has is so rare and uncommon it is difficult to predict with any certainty how his disease will progress. There is a possibility he could end up in a chronic resistance state which would mean he would remain in hospital indefinitely.

"It is possible it could perhaps erupt at a later stage.

"He has informed us consistently if he were to return to prison he would stop taking his medication or getting involved in psychological interventions. There is no doubt then his symptoms would deteriorate and he would pose a greater risk of harm to others.

"It is very unlikely his illness will be extinguished. I think this is a life-long diagnosis, and he will suffer from it for the rest of his life."

Judge Neil Ford returned Voong to Broadmoor secure psychiatric hospital under an indefinite hospital order, calling him 'emotionally void' with restrictions upon his liberty if he is ever released.

He told Voong the blade he used to stab Tom 19 or 20 times was 'a dreadful knife, in effect, a dagger'.

"You attacked him in an extremely brutal way," he said. "There was no motive for the attacks. You took no steps to cover your tracks. The weapons were bound to be found.

"Your attack on Leanne James in a secluded place at night was a truly terrifying experience for her. Your killing of Tom Rogers has caused an incalculable loss to his family.

"His adult son, who has autism, has been deprived of his father and his friend. His two sisters flew half way around the world to attend the trial. One described her brother as a quiet and gentle man.

"You are unable to explain why you acted as you did. You did not act in anger or as a result of hallucinations, delusions or persecutory thoughts.

"You are emotionally void, incapable of understanding the terror and pain of your victims, or the impact on their family and friends, or the impact on members of your own family. Yours is a respectable, hard-working family."

The court was told Voong had complained he hadn't 'felt right in himself from his teenage years, and was sent to China for a time.

"Upon your return you began to behave in a strange way," said Judge Ford. "You said you were hearing voices and having paranoid thoughts. You began laughing for no apparent reason. You would sleep all day and be awake at night. You were referred to the local mental health team, but stopped attending.

"Your illness ended with a loss of contact with reality. You have not expressed any regret or appreciation of the impact of your offending.

"Dramatically, it was pointed out you described your actions as if you were describing going to school, or buying chips.

"I am in no doubt you are seriously mentally ill. You are an extremely dangerous person. Your inner world remains a mystery."

Detective Superintendent Sean Memory said after the sentencing: "I am satisfied with the outcome of this case and the sentencing that's been passed down today.

"Although Mr Voong was suffering with a recognised mental disorder it is clear that he is a violent and dangerous man. I hope this sentence goes some way to comforting Leanne and Tom's family."
