A schizophrenic drug addict who stabbed his mother to death outside her £1million home after convincing her that she was an alien harassing him has been sentenced to life in prison.

Gregor Bauld launched a violent attack on 55-year-old Tina Bauld following an argument with her family over illegal substance use. The court heard he believed his mother was the leader of one of two warring tribes.

After chasing Ms Bauld out of the property, the 23-year-old attacked her repeatedly with a 12-inch kitchen knife in a frenzied attack that was recorded on CCTV and witnessed by her horrified father Tom.

He then went inside and told police when they arrived at the scene that his mother was a “pedophile” who “deserved it”.

It was later revealed that Bauld had a cocktail of hard drugs in his system, including LSD, Ketamine, marijuana and prescription drugs he had purchased on the dark web.

At Leicester Crown Court he admitted manslaughter by reason of diminished responsibility, but denied murder.

Tom Bauld (pictured) previously told the court his son was ‘now dead’ to me after his wife’s death.

But jurors cleared him of the charge last month after a trial in which medical experts said they believed the crime was motivated by Bauld’s diagnosis of paranoid schizophrenia rather than his illicit drug use.

When he returned for sentencing today, Bauld was sentenced to a minimum of 13 years and eight months’ imprisonment, subject to a hospital order, under Section 45a of the Mental Health Act.

The so-called ‘mixed’ order means Bauld will begin his sentence in a secure mental health unit, but will be transferred to prison if he is deemed fit enough to be released within that time.

Judge Tim Spencer KC told him that although he had a long history of ‘what the jury decided was schizophrenia’, this history was ‘characterized by his voluntary taking of drugs of abuse’ and meant he still bore heavy responsibility for his mother’s illness. Death outside the family’s home in Burbage, Leicestershire.

He added: ‘In terms of injuries covered by the law, your treating clinician, Dr. Garrett found that you are aware of the nature of your action and maintain the ability to control yourself.

‘No one can seriously suggest that drugs do not contribute to various episodes of psychotic behaviour.

‘You started taking marijuana when you were 13 or 14. You were socially inept and found solace in drugs. This has clearly contributed to your psychotic episodes, which have now spanned eight or nine years.

‘You should be aware that your drug addiction was a factor in your mental health problems, but you continued to take them.’

The judge said that before the March murder, which he described as “unimaginably horrific” and a “brutal, shocking taking of a life”, Bauld was “intensively engaged in accessing illegal drugs and highly abusive drugs”.

He added: ‘You, Gregor Bauld, were aware that your drug use was a contributing factor to mental health problems but you continued to take drugs.

The 23-year-old, the only child of Tina and Tom Bauld, was jailed for life after stabbing his mother to death in a frenzied attack.

‘Taking all this together, while you accept that this is a case of manslaughter and your responsibility is diminished, your responsibility for your own psychotic state is clear and severe.

‘In terms of impairment of mental ability, Dr Garrett found that you are aware of the nature of your action and retain the ability to exercise self-control. ‘The responsibility of killing your mother is very heavy.’

Judge Spencer said the impact on Bauld’s family when his father told the jury he no longer wanted to live was ‘incalculable’.

‘You ended the life of one of your parents and put the other parent in this miserable situation,’ Judge Spencer said.

At Bauld’s trial, it was learned that the only child was living with his 69-year-old father, a company manager, and his mother at the time of the attack, which took place at 11.15 on the morning of March 3.

Prosecutor Gordon Aspden told jurors: ‘In all respects this defendant was a well-bred young man with two loving parents, living in a comfortable and relatively affluent home environment.

‘But as he got older and entered adolescence, his life was devastated by chronic drug use and associated mental health problems.’

Mr Aspden said Bauld had had a “long-standing drug problem” since he was 13 or 14 and was “in the grip of a devastating cycle of drug use” at the time of the murder.

Mary Prior, defending, told today’s sentencing hearing: ‘This defendant had an underlying condition of schizophrenia which had been untreated since at least 2022.

‘Prior to this he had a history of simple mental health problems which occurred whether he was taking drugs or not.

‘This is a man who is very seriously mentally ill. He truly believed that the world was at war between two tribes, and the woman he loved most became the leader of one of those tribes, was abusive to her, and wanted to kill the world.

‘It is right and fair to say he was using drugs. In our opinion, it is impossible to say how much this affects what is happening.

‘He is still very, very severely schizophrenic as he is on a regime where he has to take his medication and cannot take illegal drugs.

‘The level of schizophrenia is still very high. ‘He still poses a danger to himself, other prisoners and others he comes into contact with.’

Three days before Ms Bauld’s murder her son found a new job with a logistics firm, which was ‘great news for everyone involved’, the hearing heard.

But the next night, Mr Bauld found his son sniffing drugs in a saucer after hearing “buzzing” noises coming from his room and had to put him to bed because he was “so dazed he couldn’t function properly”.

The court heard he seized and hid the items and told Bauld the next day that he had thrown them away; this left him ‘very emotional’.

Mr Aspden said Bauld had promised not to take any more drugs but was seen desperately searching for something in his car on the morning of the fatal attack on Ms Bauld.

His suspicious father searched under his tracksuit while he was in the shower and found two plastic bags containing tablets, which led to an argument between the two.

The jury heard Mr Bauld said he disposed of the drugs as the young man became “angry, agitated and emotional”.

Mr Aspden added: ‘In response the defendant became very angry, agitated and emotional. In his own words, he started yelling that he needed pills to control his anxiety and nerves.

‘Mr Bauld said he offered to take the defendant to doctors for help; It’s something he’s offered many times before.’

The court was told Mr Bauld joined his wife in the downstairs living room while their son was heard ‘hitting it’ upstairs, resulting in Mrs Bauld deciding it would be ‘better for her to leave the house’.

He went to take the family dog ​​for a walk but Mr Aspden said the next thing Mr Bauld remembered was his wife shouting ‘Gregor had a knife’.

The prosecutor said: ‘The defendant then chased Tina down the corridor and out the front door.

‘When he came out he remembered the defendant stabbing him twice with a knife. ‘He stabbed her again while she was cowering on the ground.’

Paramedics were called and were greeted with a ‘truly horrific’ scene where Ms Bauld was ‘seriously injured’ and bleeding on the floor.

Mr Aspden said that despite ‘frantic and protracted’ efforts to save him, he was pronounced dead where he lay.

He added that Bauld ‘seemed disinterested and his demeanor was quite matter-of-fact’ when told of his mother’s death.

Toxicology tests revealed traces of LSD, ketamine, ketamine’s sister drug norketamine, marijuana and a sedative called diphenhydramine.

Mr Aspden said the results, apart from cannabis, were consistent with all drugs taken in the last 24 hours.

Prosecuting barrister Gordon Aspden KC said: ‘There was ample evidence of long-term and persistent illicit drug use, which could have had a significant impact on mental health.

‘The defendant was aware of the effects these drugs, having previously been sectioned, could have on his behaviour. Still, he chose to use these drugs until his mother’s death. In this case, he made choices.’

The court was told Ms Bauld suffered four separate stab wounds on the morning of the attack and a pathologist determined the cause of her death was a wound to her back.

Sentencing the defendant, Judge Timothy Spencer KC said: ‘This murder was unimaginably horrific. This was a brutal and shocking killing.

‘Your mother died on the road outside your house and her house; Your father was with you and his life ended as you watched.

‘The impact of killing your mother in this way is rightly described by the prosecution as incalculable.

‘You were aware that your drug use was a factor in your mental health problems but you continued to use drugs.’
