A PARANOID schizophrenic killed his mother after she refused to forgive him for stabbing her in the neck and sucking her blood.

Ian McKenzie said he stabbed his mother, 55-year-old Alison McKenzie, seven times because he believed she would come back to life and the voices inside his head told him to do it.

The 34-year-old who has suffered with the condition for more than 10 years was handed a hospital order after denying murder but pleading guilty to manslaughter.

McKenzie, who appeared at Teesside Crown Court via video link from Roseberry Park Mental Health Facility, handed himself to police after attacking his mother at their home in Middlesbrough in March.

He admitted in a police interview that when he was 16-years-old he stabbed her in the neck and sucked her blood – but Ms McKenzie never reported the attack.

Nick Dry, prosecuting, said: “That day he apologised for stabbing her when he was 16 but when she didn’t forgive him he attacked her.

“He walked into a police station and confessed to killing his mother.

“Alison McKenzie was found dead on the settee with stab wounds to her neck and face and a small kitchen knife was found.

“There were seven stab wounds to the head and neck and the jugular vein. There were three further punctures to her face and bruises to her head and body.”

The court heard that McKenzie stopped taking his medication up to six days before killing his mother – and this was likely to have caused a decline in his mental wellbeing.

Mr Dry said: “Four to six days he stopped taking his medication. He stopped due to the side effects including salivating.

“Failure to take his medication caused a significant decline in his mental state and he descended into a violent nature.

“He said he killed himself the previous day by jumping off a bridge onto a train and came back to life to kill her.

“He said he expected her to reappear just as he did the previous day. He could not understand why she didn’t, he did it for the devil and everyone in his head told him to do it.”

Mr Dry added McKenzie became addicted to cocaine and cannabis during his early teenage years and his mother endured her own mental health and addiction battles.

Giving expert evidence, Doctor Christopher Green said: “One of the main problems in managing schizophrenic patients is keeping them on medication.

“It is common for them to discontinue their medication because of a lack of insight of their mental health. It is a characteristic of the disorder.

“I cannot see Mr McKenzie being released from hospital for the foreseeable future.”

Judge Simon Bourne-Arton gave McKenzie a hospital order and a restriction order under the Mental Health Act which prevents him from being released from the mental health facility unless overturned by the Home Office or a Mental Health Tribunal.

Judge Bourne-Arton said: “Mr McKenzie has had a long history of mental illness.

“There was violence to his mother, particularly when he was 16, when he admitted to stabbing her and sucking her blood.

“His mother had a number of her own demons including drug and alcohol addiction, as did the defendant.

“In light of this he has committed few convictions, the last one was in 2004 when he served a short time in prison.”
