Schizophrenic killed father for 'disrespect to all rappers'

Enrique Parada Castro, a 58-year-old Chilean exile and Spanish teacher, was struck so forcefully with a blunt instrument police thought he had been shot in the face.

His son, Omar Parada Blanco, later told doctors he did it after his father made comments about his low-slung jeans that showed "disrespect to all rappers".

Mr Parada Castro had been a student leader in Chile and fled to Britain in the Seventies after he was jailed for two years for his opposition to General Pinochet.

He became the head of modern languages at Hackney College and lived in Cricklewood.

Parada Blanco, who denied murder but admitted manslaughter, was admitted to the Park Royal centre for mental health in April 1998 when he was first diagnosed with paranoid schizophrenia, the Old Bailey heard.

It started a pattern of being treated in hospital before being discharged, failing to take his medication and launching unprovoked assaults on strangers.

On 9 November 2007 he went to hospital with a cut to his arm after smashing a television when he thought he heard voices coming from it, and he was sent back to Park Royal. David Jeremy QC, prosecuting, said: "It was considered that he posed a significant risk to others. His condition was unstable and at times threatening."

However he was let out overnight for Christmas and for a week over New Year. He travelled with his father to Cambridge to stay with a family friend but became "agitated" and they returned to the family home in Kingsbury on New Year's Day.

After an argument, he beat his father to death with a blunt instrument and stole his laptop, before returning to hospital as if nothing had happened.

The killer's mother was in Chile and his sister Victoria, 28, was in Ireland with her boyfriend at the time of the murder. The body was not discovered until they returned a few days later.

Judge Stephen Kramer adjourned sentencing until next month for further psychiatric reports to be prepared.

He will be locked up indefinitely for psychiatric treatment but the judge said he was considering ordering a life term in prison in the event he recovers from his mental illness.
