The conviction of a teenager for the murder of a homeless man and a knifepoint robbery have come together to paint Jesus Green as a particularly dangerous Cambridge area to find oneself in after dark.

Jack Robinson, 18 and of an unknown address, was found guilty of murdering 52-year-old Raymond Boyle in the early morning of 22nd June 2011, after wavering back and forth between admitting only to assaulting the man and additionally admitting his intent to murder him as well.

Boyle’s body was found floating in the section of the River Cam running through the Green roughly one hour after the murder took place, and Robinson was accused of intentionally drowning him.

Another co-defendant in the Boyle case was acquitted of both of the charges against him, capping the two-week trial. Daniel Mynott, 17, of Cambridge, had been charged with causing grievous bodily harm with intent in addition to a separate charge just for having caused grievous bodily harm.

However, Mynott’s role in the attack was thrown in doubt last week when a police investigator told the jury that Robinson had confessed to the murder less than 48 hours after it took place, before retracting his admission after initially putting it in writing.

During the same hearing a recording of Mynott begging Robinson to tell the police of his innocence was also played to the courtroom.

Robinson has not yet chosen to appeal, and will be sentenced on Friday 2nd March, according to the current Cambridge Crown Court docket.

Meanwhile, last Wednesday night, a 20-year-old victim was accosted by two other young men while walking on a path through the park. One of the robbers brandished a knife, and the victim was coerced into handing over his iPhone and some cash.

The robbers, who had the hoods of their sweatshirts up during the exchange on the darkened path, have yet to be identified.
