Redvers Bickley, the Rhyl man who accepts that he knifed four members of the same family which led to the death of his housemate Tyler Denton, told a murder trial jury on Friday that he planned to kill himself.

Giving evidence today on day five of his trial, he said that he had made a promise that however many times he failed “one day I am going to kill myself, even if it takes the rest of my life.”

The jury at Mold Crown Court was told that the defendant wore a black ring on the wedding finger of his left hand.

Asked by his barrister Patrick Harrington what was the significance of it, he said it was a ring given to him by his stepmother Penny, his mother’s partner.

He said he also wore a piece of hair on his wrist which had been given to him by his mother.

It was then that he told how he had promised to kill himself.

Asked by prosecution barrister Mr John Philpotts when he is going to do it, he said that he did not know.

When asked why he had not killed himself on the night last September when he stabbed four other people, he said that he tried to do so.

The jury has heard evidence given by two psychiatrists – called by the defence and the prosecution.

Dr Noir Thomas for the defence said that Bickley suffered from a mental disorder which significantly impaired his ability to control himself.

He said that Bickley had unusual beliefs, including his alter ego James, and had paranoid ideas and suspiciousness. He felt people were plotting against him and being derogative about him.

Bickley had abnormal and bizarre ideas and Dr Thomas said his view was that he best fitted a schizotypal disorder which he felt had been present for a number of years.

Bickley displayed seven of the 14 possible symptoms.

He had a very distorted sense of himself and did not show any particular emotion when discussing what had happened – and had a limited response in terms of his emotions He was distrustful of people and anxious and socially awkward.

Relationships were marked by his expectation that other people are going to harm him.

His claimed second identity of James together with violent imagery was quite abnormal bordering on psychotic.

His rage was more frequent and intrusive leading up to the offences.

He had been seen by a number of physicians at Ashworth Hospital but he did not warrant hospitalisation.

It was a complex case.

Dr Thomas said the fact that he was not offered admission did not mean he did have a mental disorder.

His risk around self harm could be appropriately managed and he was complient with medication.

Dr Thonas said that the charges against him were quite difficult to reconcile with the individual he saw in interview.

He suffered from a recognised medical condition – an abnormality of mental functioning arose arising from a schizotypal disorder.

It significantly impaired his ability to have self control, and felt frustration and sadness, but he specifically denied anger, the doctor said.

Dr Thomas a consultant psychiatrist at Ashworth, said Bickley was hoping for a longer term, meaningful, relationship with Tyler, was frustrated by the relation and recognised that it was complicated.

He had made a number of advances towards other females but they were not reciprocated.

Bickley had told how he had liked another girl but she barred him from her Facebook account, so he created an account to monitor her comments.

Bickley admitted viewing porn and told how he liked female domination.

He imagined harming people who bullied him and said his alter ego James would use knives and swords to mutilate.

Consultant psychiatrist Dr Sandeep Mathews said Bickley had no previous contact with psychiatric services He claimed his alter ego, which he named James, spoke to him from an early age.

Dr Mathews, called by the prosecution, described him as a voice in his head asking him to do things.

However it was self reported with no corroborative evidence – he had not been independently observed being disturbed by them.

Dr Mathews said: “My opinon is slightly different. He was socially awkward and had difficulty in relarionships – I am not entirely convinced, on balance he did not think he was suffering from a schizotypal disorder.

Even if it was accepted that he did, it was doubtful that he suffered from an abnormality of mental functioning at the time.

|His recollection was patchy but he recollected stabbing Cody, returning to check on Tyler, and stabbing Paul. His comments indicated an awareness of his conduct and actions.

“I did not think that he could not exercise self control,” he said.

Bickley was angry about the fact that Tyler left him alone and that she and the others left for a drive without telling him. He accessed her ipad and noticed comments about him which increasingly made him angry.

He was intoxicated at the time which prevented him from thinking clearly. He said he went for a walk and came back and was upset, and he made a decision to act on his anger.

“I think when he stabbed the group of people and from the footage he was quite composed in his actions,” he said.

His intoxication disinbited him.

Dr Mathews said he did not think his acts could be explained by a recognised medical condition.

“I do not think so – even if he had a medical condition there was a normal range of human behaviour and emotions including anger,” he said.

Bickley, 21, of LLys Aderyn Du in Rhyl, denies murdering Tyler and attempting to murder her dad Paul and her two sisters Shannen and Cody in September of last year.

Prosecuting barrister John Philpotts, prosecuting, said psychiatry relied to a very great extent on the veracity of the defendant’s account, his accuracy.

“You are very highly dependent on the assumption that the subject had told you the truth,” said Mr Philpotts, cross-examining the psychiatrist called by the defence, Dr Noir Thomas.

He had told the doctors some things which were quite different from which he had told the police and the jury, he suggested.

“People without any kind of mental disorder have been known to fantasise about hurting other people,” he said.

There were plenty of odd people wandering around but they are not mentally disorder.

Normal people lost their temper sometimes.

Mr Philpotts suggested that whenever Bickley was required to confront something hostile or damaging, he put it down to her alter ego James, and the harmless ones to himself.

When he knew he was not being admitted to Ashworth Hospital he had said “I am looking at decades.”
