A north London man has been found guilty of two murders and a string of "senseless" assaults. [17 May 2012]

Turkish-born Ali Koc, 30, pounced on his victims during a "wanton" crime spree of "violence for violence's sake", leaving them battered and bruised in parks and woodland close to his home.

Koc, of Hornsey, was convicted by a jury after a month-long trial at Woolwich Crown Court, a court official said. He will be sentenced for the two murders and five charges of grievous bodily harm on Friday.

Two elderly men died from their "catastrophic" injuries - one had been out on a routine morning walk which "cost him his life", prosecutor Brian Altman QC said during the trial.

Koc selected lone men during a four-week period in January last year. He targeted dog walkers, joggers or people who were simply out walking - in broad daylight, usually before mid-morning or around lunch time.

His victims, aged between 29 and 84, were "violently and indeed senselessly" subjected to either head-butting, punching, kicking or battery with lumps of wood, Mr Altman told jurors.

Victor Parsons, 67, died on February 22 last year, while Keith Needell was pronounced dead on July 16 the same year - nearly six months after he was set upon, at the age of 84. The five other men were not gravely injured but "that was not for want of trying", Mr Altman said.

Scotland Yard said detectives are not ruling out the possibility that Koc may have attacked other people.
