A son who stabbed his mother 18 times is to be detained indefinitely at a psychiatric hospital for treatment.
Taylor Lopez-Kerr attacked Leona Lopez (52) without warning as she watched television in the living room at home.
It was 7pm on Sunday September 20 when she suddenly realised he was standing next to her holding one of her kitchen knives.
Bizarrely, he kept calling her "Nathan" as he inflicted multiple injuries to the left side of her body, on her leg, arm, side, breast and back.
The knife was left embedded in her lower back and had to be surgically removed.
Ms Lopez, of Pitchens Close, Beaumont Leys, Leicester, screamed for help but her younger son, Mason, then 18, had fallen asleep upstairs.
Her partner, George Kerr, had just popped out to fill his car with petrol ready for work the next day.
When he returned, he found Ms Kerr bleeding heavily on the floor and gasping to breathe, with a punctured lung.
Taylor immediately handed himself into the police, asking to be arrested, saying he had just stabbed his mum and it was "attempted murder."
Leicester Crown Court heard that Taylor, 23, who suffers from schizophrenia was too mentally ill to enter a plea to a wounding with intent charge and could not stand trial to establish guilt or innocence.
However a jury heard the facts of the case and concluded Taylor had committed "the act" of stabbing his mother.
Sentencing Taylor, Jude Michael Stokes QC said: "What you did last September to your own mother could have resulted in her death.
"She has a permanent disability now as a result; happily not the most serious.
"You have a history of aggressive and violent behaviour.
"From your mother's evidence, when you attacked her you were seriously mentally ill.
"In her words it wasn't as if it was you attacking her and it appeared to be someone quite different.
"You suffer from a mental disorder that requires you to be detained in hospital you require treatment at Arnold Lodge (a medium psychiatric hospital, in Leicester).
"But given the violence, particularly to members of your own family, you pose a risk not only to yourself but members of the public.
"It's necessary for the court, supported by two psychiatrists, that you remain the subject of section 41 of the Mental Health Act, without limit of time."
Judge Stokes told Taylor he would not be released until "you no longer present a risk to yourself or anyone else."
Earlier consultant psychiatrist, Dr Gillian Bennett, of Arnold Lodge, told the judge that Taylor had been diagnosed with a psychotic mental disorder and was being treated for schizophrenia.
Ms Lopez's statement, video recorded from her hospital bed the day after the attack, was earlier played in court.
She said: "I thought he was going to kill me."
"He was just not Taylor; like he was possessed and I couldn't reason with him.
She was off work for a month; but has scars and nerve damage in her leg.
She said Taylor's personality changed after he began taking cannabis in 2013, resulting him being aggressive.
He also fell off his bike and banged his head in May 2013.
Two consultant psychiatrists' reports stated his former cannabis use could have precipitated or exacerbated his mental illness.
