A man accused of murdering Randy Robinson told a detective he had an alibi — but would not let the officer access his phone to prove it.That information was given in evidence yesterday by Windol Thorpe, who took DNA and gunshot residue swabs from Jay Dill after his arrest over the killing.Mr Dill, 23, and Devon Hewey, 24, are on trial at Supreme Court accused of shooting 22-year-old Mr Robinson dead in an alleged gang-related killing on March 31, 2011.Prosecutors allege that Mr Dill, of Southampton, was riding as a pillion passenger on a motorcycle when he used his left hand to pull out a gun and shoot the victim as he walked up Border Lane North, Devonshire. Mr Hewey, 24, is alleged to have been the rider.Both deny charges of premeditated murder and using a firearm to commit that crime. Det Con Thorpe said he dealt with Mr Dill following his arrest in the hours after the murder. As he was taking forensic samples from him, he recalled, Mr Dill said: “I had nothing to do with that. I was at the Boat Club having a drink.”The detective said Mr Dill went on to tell him that a girl had sent him a message on his cell phone telling him about the shooting. However, he said, Mr Dill refused to state the name of the girl or give the password for his cell phone.When it came to signing paperwork relating to a later police interview, Det Con Thorpe said: “I noticed Mr Dill used his left hand to sign documents.”The case continues.
