Marie Harding's killer told how he wanted to carve someone up during a trip to the South Coast, the Old Bailey heard.

In an interview about the fatal stabbing of Brighton and Hove Albion ticket seller Mrs Harding, from Southwick, Daniel Gonzalez said he had got off a train at Worthing and was "walking down these alleyways with a knife, waiting to carve up someone.

"The knife was six inches long. It was like a butcher's knife used to carve up bits of meat. I was going to the first place I could to kill someone.

"I was in the bushes and just leapt out and stabbed her in the centre of her back. She screamed.

"I rugby tackled her and stabbed her in the stomach twice and put my hand over her mouth so she couldn't scream. She tried to resist."

Asked why he had stabbed Mrs Harding, Gonzalez replied: "I just could not handle it. I was hearing voices.

"I could not go on with life anymore. My head was just in the clouds man. I was really wound up."

Gonzalez said he had heard voice. He said: "I was looking up from miles away. I could see children playing and people playing.

"I was sort of miles away ... blown.

"I just thought I would get on this and get away into the clouds. I was thinking about fairies now - know what I mean?"

He was referred to a note he made, found later, in which he allegedly stated: "I got that old bitch proper, bloodbath, pouring out of her throat ..."

An officer asked him who he was writing about. Gonzalez said it was about the people in Highgate, which the court heard referred to Jean and Derek Robinson.

Gonzalez told police in interviews that he should "go to the electric chair" as he confessed to knifing the retired paediatrician and his wife to death in a frenzied attack.

Daniel Gonzalez, 25, of Woking, said he had no idea who his victims were.

"I just wanted to hurt someone. I wanted to kill someone... It was the luck of the draw that I went into their house.

"I am sorry. I want to do the time man. I want to do the time. I just want to get locked up... in fact, I should go into the electric chair, man."

Tapes of Gonzalez's police interviews about the killing of Mr and Mrs Robinson at their home in Highgate, north London, were played to the Old Bailey jury trying him yesterday.

The defence accept he was the killer and that he killed two other victims earlier. But they claim he was suffering from auditory hallucination voices commanding him to kill - which diminished his responsibility and meant he was guilty of the manslaughter and not the murder of the four. The trial continues.
