A boy who killed his stepfather in a 'horrific' attack involving an electric drill told police that the voices in his head made him do it, a jury heard.

Army cadet Vladimir Ivashikin allegedly killed university lecturer Barry Hounsome at his home in Southcroft Road, Gosport, prosecutors told Southampton Crown Court today (1 July).

Mr Ivashikin, 22, denies murder.

The jury heard how on top of the bags was a sheet of paper with the words “I am so so so so sorry” written on it.

The then-16-year-old also made a 999 call in which he confessed to the killing and claimed: “Something in my head told me to do it”.

During the call, he told the operator that he had hit Mr Hounsome “round the head with a hammer a load of times” and “stabbed him a couple of times”.

“He wasn’t attacking or anything. He didn’t do anything wrong.

“Something in my head told me to do it. It wasn’t self-defence or anything.

“It is such a shame because I had such a nice life with my family. I understand the severity of it, I know that.”

Officers smashed through a patio door to get inside and were confronted with the 'horrific scene', Mr Price said, adding: “Paramedics arrived at the house.

"They could see immediately that Mr Hounsome had sustained massive head and brain injuries of a gravity incompatible with life.

“He was pronounced dead at seven minutes past six that evening.”

He provided a detailed account of what he said he had done setting out that “the responsibility lay with the voices in his head”.

The prosecutor added: “He said that he had tried to argue with the voices but they became even more insistent and aggressive.

“He had heard the voices demanding he kill someone previously. But he said he had always been able to argue them away.”

He was later charged with murder and was transferred for treatment at a secure psychiatric hospital in Calmore where three doctors diagnosed him with paranoid schizophrenia.

The trial continues.
