On September 15, 2004 Gonzalez told 61 year old Peter King who was walking his dog with his wife in Hilsea, Portsmouth that he was going to kill him. He was fought off and fled to Hove where he stabbed 76 year old Marie Harding whilst wearing a hockey mask, a la Jason Voorhees. After this, he returned to his home in Woking. He concluded that the reason for his failure to kill Mr King was because his knife was too small.
He traveled to Tottenham, where he drank until the early hours of the morning. At 5:30 AM he left 46 year old Kevin Molloy for dead after stabbing him in the face, neck and torso with a pair of large knives he had stolen from a department store. At 7:00 AM he made a forced entry into the Hornsey house of Koumis Constantino, but was fought off after stabbing his arm. By 8:00 AM he was in Highgate, where he randomly tried to gain access to houses. He succeeded in murdering a geriatric couple, the Robinsons, an experience he claimed was "orgasmic". He was arrested at a tube station after a decorator saw him naked and covered in blood in the Robinson's house.
He saw the Columbine killers as heroes and intended to perpetrate a similar crime to theirs.
Gonzalez tried to claim that he was not guilty by reason of insanity, although this was rejected. He was given six life sentences and the trial judge recommended that he should never be released. It was revealed that he was a habitual drug user who had run naked down a street whilst drunk a week before he was arrested.
Gonzalez was found dead in his cell at Broadmoor Hospital on August 9, 2007. He was believed to have committed suicide.
