A paranoid schizophrenic killed his flatmate and cut off his head in a frenzied attack after suffering from delusions that he was being persecuted, a court heard today.
Karl Addo, 30, suffered years of mental illness which led to an extreme complex that he was being assaulted and injected with drugs.
He snapped on the day he had been told to leave the flat in Bournemouth, Dorset, he shared with Spanish student Sergio Marquez, 23.
He hit him with a cleaver and stabbed him in what was a "prolonged horrific and very violent attack"
Addo absconded from a mental health unit the day before a tribunal in October 2011 decided he should be sectioned.
He then "disappeared" from mental health services before he moved to Bournemouth in May 2012. He killed Mr Marquez, a hotel waiter, on July 17 last year - nine months later.
