Man admits killing mother at her Littleborough home
A man who thought his parents were members of a satanic paedophile conspiracy has admitted killing his mother in Greater Manchester.
Paranoid schizophrenic Matthew Brierley, 45, admitted the manslaughter of Glennis Brierley who was stabbed after a row over his missing property.
Brierley killed his mother, 64, in December 2013 - two days after he moved back to her home in Littleborough, Manchester Crown Court heard.
He will be sentenced on Wednesday.
Ms Brierley, who was a psychotherapist, was found dead at her house in Calf Hey, Shore Road with a kitchen knife by her side.
The court heard police went to the property after Brierley called 999 from a phone box and said: "I just murdered somebody".
His mother's body was found with stab wounds to the neck and chest.
Brierley said: "I just went for her... I watched myself stab her.
"Part of me believed you could murder somebody and it would be justified."
Brierley suffered from delusions and thought his parents were members of a satanic paedophile conspiracy, the court heard.
A forensic psychologist told the court Brierley had paranoid schizophrenia and was "largely blameless for his actions because of his disease".
