A mentally-challenged gunman who shot a former friend after they got caught up in rival gangs has been convicted by a jury.Twenty-five-year-old Noet Barnett, who has a mental age of nine or ten, left victim Jeremiah Dill with multiple gunshot wounds.Prosecutors believe the attempted murder was revenge by Barnett, a member of the 42 gang, against the victim as a member of Parkside.Barnett told detectives the pair had not spoken since “war” broke out between the factions, even though he was the godfather to Mr Dill’s child.Three of Barnett’s cousins, who had links to 42, had been murdered in the months before the crime. Barnett held the Parkside gang responsible, and police believe he shot Mr Dill in a bid to avenge their deaths.Mr Dill was attacked in broad daylight as he chatted with friends outside the One Stop grocery store on Parson’s Road, Pembroke, around 10am on October 4, 2010. He told the trial a motorcycle-riding gunman arrived and taunted him with the words “what happened pussy?” before opening fire. He suffered one gunshot wound to each thigh and one to his buttock as he ran away.He could not see his attacker’s face due to the dark visor he wore, but recalled throwing his helmet at the gunman and trying to kick him off his bike.Mr Dill, 28, grew up with Barnett in Spanish Point, Pembroke. Barnett is godfather to his young daughter and was in a relationship with his sister, Tookie Binns, at the time of the shooting.A key witness for the prosecution was a woman who was chatting with Mr Dill when he was shot, and ended up running for her life. She told the jury she’d known Barnett since school days and recognised him as the gunman due to his distinctive mouth and “small dark smoker’s lips”. She’d seen him earlier that same day in the same clothes, on the same bike.The witness's name cannot be published due to a reporting restriction imposed by the judge.Police gang expert Alexander Rollin named Barnett as a member of 42 and Mr Dill as a member of Parkside. The defendant told detectives that he had “no beef at all” with Jeremiah Dill and claimed he was travelling to a job interview at the time of the shooting.The gun Barnett used to shoot Mr Dill was found in bushes on East Gate Lane, Pembroke on December 22 2010, more than eleven weeks after the attack. A ballistics expert linked the weapon, a Rexio RJ Serie .38 Special revolver, to the shooting of Mr Dill and three other shootings in Bermuda, all believed to have been attacks on Parkside.Barnett’s DNA was found on the gun, along with that of a 42 member named Kofi Dill and a woman named Thayja Simons. All three were arrested. Kofi Dill was later charged and pleaded guilty to handling the firearm, and was jailed for eight years. Ms Simons was also charged, but prosecutors dropped the case.Police found a damning cell phone video when they raided Kofi Dill’s home on December 22, which they played to the jury during the Barnett trial. It showed Barnett, Kofi Dill and friends from the 42 gang fooling around with what appeared to be a semi-automatic pistol and making threats towards Parkside.Although the defendant elected not to give evidence himself, his lawyer Victoria Pearman called upon psychologist Guy Fowle to share his expert opinion with the jury. He revealed Barnett has a “very low” IQ of 63, which puts him in the bottom one percent of the population. Dr Fowle described him as “mildly retarded,” with a mental age of nine or ten.The jury of eight women and four men found Barnett guilty of attempted murder and gun possession by majority verdicts after just over four hours of deliberations. They convicted him by unanimous verdict of handling the gun.Barnett showed no visible reaction, apart from bowing his head slightly. Puisne Judge Carlisle Greaves remanded him into custody, and his sentencing date will be fixed next month.Speaking as Barnett was led to a prison van, Detective Chief Inspector Nicholas Pedro of the Serious Crime Unit said: “This marks the 13th person convicted for a serious crime in Bermuda since the start of the year, and the 12th trial which has resulted in a conviction for serious crimes. Obviously it’s very pleasing to end the year on such a high note. It was a very challenging investigation from the outset, which I think was shown by the evidence. The investigators from the Serious Crime Unit did an excellent job in bringing that all together and this was further enhanced by prosecutors in the office of the DPP.”
