TEENAGER Jack Robinson, 18, has been found guilty of murdering homeless man Raymond Boyle on Jesus Green, Cambridge.

Robinson, formerly of Royston but currently of no fixed address, stamped on the 52-year-old's head before dragging him into the River Cam.

He then casually walked back with his friend Daniel Mynott, also 18, to Mr Mynott's home in Haviland Way, Arbury.

A jury at Cambridge Crown Court this afternoon unanimously found Robinson guilty of murdering Mr Boyle in the early hours of June 22.

Mr Boyle's body was discovered face down in the River Cam shortly after 2am and Robinson was arrested later that day.

He admitted assaulting Mr Boyle but denied dragging him into the water.

The jury at the Cambridge court heard how his account changed many times during police interview and later in court.

Mr Mynott had gone to Jesus Green with Robinson on the evening of June 21 to drink.

He was charged with causing grievous bodily harm with intent to Mr Boyle.

The jury, however, today unanimously cleared him of this charge and a lesser one of grievous bodily harm.

Robinson showed no emotion when the verdict was read out but later shook his head.

Detective Chief Inspector George Barr, who led the investigation, said: "This was a savage, unprovoked attack on a defenceless man.

"That assault was bad enough, but for Robinson to drag him, barely conscious, into the water where he stood no chance of survival, was sickening."
