A teenage army cadet who violently killed his stepfather has a 'delusional belief system' involving artificial intelligence, jurors were told on Tuesday.

Vladimir Ivashikin claims he has been receiving information by an organisation - called 'The Makers' - who hope to create a world which is run by machinery.

At the age of 16, Ivashikin attacked Dr Barry Hounsome in his home with a hammer, knife and electric drill, blaming 'voices' in his head for his actions.

The now 22-year-old was diagnosed as suffering from paranoid schizophrenia and after pleading guilty in 2019 to manslaughter due to diminished responsibility was sent by a judge to a secure hospital.

However, in 2022, Ivashikin allegedly admitted to a nurse that he had 'fabricated' his symptoms.

He is now on trial for murder after doctors concluded he wasn't mentally ill.

Today, jurors at Southampton Crown Court heard evidence from two forensic psychiatrists who assessed him last year and told the court they believe Ivashikin is in fact suffering from a psychotic illness - which is most likely schizophrenia.

Dr Bradley Hillier who is based in Jersey told the court he had created a 'delusional world'.

He said: "There was a big system of bizarre ideas that somehow all linked together in quite a complex way.

"Involving this idea about the makers, the human species being reproduced, genetic materials and things like this."

It was heard Ivashikin had been cutting off bits of flesh from his body in 'geometric' patterns, boiling them in the kettle, and eating them in order to attract the attention of 'The Makers'.

Dr Hillier said he believed he was sufficiently mentally unwell with psychosis, which is one that detaches him from reality - and is most likely schizophrenia.

In a statement read to the court, Dr Lucy Bacon, who is based at Guild Lodge Mental Healthcare Hospital in Preston, recalled him telling her: "Everything from my past from before the offence is bittersweet."

"Mr Ivashikin confirmed he had had no contact with his GP about mental health or with mental health services prior to his offence," she said.

Speaking of 'the voice', Dr Bacon said Ivashikin told her that it was of an Eastern European male, in his 30s or 40s, who was not known to him.

Ivashikin felt as if he had to follow the 'disturbing' and 'shocking' requests of the voice in order to 'reduce its intensity'.

Ivashikin said 'I just wanted to get rid of that', the court heard.

Describing the attack at the family home in Gosport, the 22-year-old told the doctor the voice told him to kill his stepfather and he felt as if he did not have control over his body.

After Dr Hounsome, 54, was dead, the voice told Ivashikin 'You are finished now', Dr Bacon said.

The trial continues.
