Middletown gang member Antonio Myers was convicted yesterday of slaying rival gangster Kumi Harford in a hail of bullets.Prosecutors say Myers attacked the victim, a member of the 42 gang, in payback for another 42 member insulting a Middletown man’s mother.He and an accomplice struck just 90 minutes after that incident at Devonshire Recreation Club in the early hours of December 5 2009. They opened fire on Mr Harford, 30, as he sat in his distinctive electric-blue car in the 42 gang heartland of St Monica’s Road.At least 12 shots were fired from two different guns. Four bullets hit the victim, who was married with a 21-month-old son, and he was pronounced dead shortly afterwards.The trial heard how the same two guns have also been used in eight other murders and attempted murders, including an attempt on the life of Mr Harford's’ brother, Jakai Harford [see separate story].Neither of the weapons has been recovered, and Myers’ accomplice in the crime remains at large. Police remain keen to bring that person to justice.Detective Chief Inspector Nicholas Pedro said: “The case remains open.“Although a conviction has been obtained, it doesn’t mean they get a free pass.”Two older men, who were homeless drug addicts at the time of the shooting, gave evidence for the prosecution during the two-week Myers trial.Andrew Laws, 52, and Edwin Darrell, 55, both said they’d heard him speak of destroying the evidence.Mr Darrell said Myers even confessed to the killing when he bumped into him on Parsons Road just minutes after it happened.Mr Laws and Mr Darrell have now been relocated overseas as part of the witness protection programme.Deputy Police Commissioner David Mirfield said: “This demonstrates the police service will do everything we can to ensure witnesses’ evidence is heard and delivered to the court.”Detective Chief Inspector Pedro added: “This was very much a case about people stepping forward and doing the right thing. It demonstrates that we can get the right results. Justice can be done with people stepping forward and doing the right thing.”Armed police who arrived on Myers’ Middletown home turf soon after the killing found several items of his clothing on a bonfire behind a house he was known to frequent.The clothes had his DNA on them, and two items also contained gunshot residue that prosecutors say proved his role in the crime.Myers’ mother, Deborah Maynard, 56, took the witness stand during the trial to give evidence for the defence. She said her son had been asleep on the couch in her Rambling Lane home just half an hour before the shooting.However, the jury found him guilty by unanimous verdicts after just over three hours of deliberation yesterday, prompting Ms Maynard to break down in sobs of distress.Myers, who is nicknamed Stone due to his cold nature according to prosecution witness Mr Laws, was impassive after the verdicts came in.He will be sentenced at a later date, and is facing a life sentence. Puisne Judge Carlisle Greaves ordered background reports and a date for the sentence will be fixed later.The trial is the ninth gun-related case resulting in a guilty verdict since May 2010.That includes Alvone Maybury, 25, who pleaded guilty yesterday to conspiring with Anthony Swan to shoot gangster Raymond [Yankee] Rawlins last year.Both men have been named during court proceedings as members of the 42 gang. Swan has already been convicted and jailed for 12 years and Maybury will be sentenced later.Four other men are serving sentences ranging from seven to 25 years for various other shootings and another is awaiting sentence for bullet possession.
