Not guilty: Cook County Judge Dennis Porter, cleared 46-year-old Officer Dante Servin (left) who shot Rekia Boyd, 22, (right) dead in Chicago in March 2012 . She was gunned down on March 21 as she stood with friends outside a property in Chicago's Lawndale neighbourhood. According to James Montgomery the family's lawyer, Servin pulled up to the group in an unmarked vehicle and told them to 'shut up'. Boyd was standing with her friend Antonio Cross, who reached into his waistband, pretending he had a gun, and charged at Servin, the court heard. She died after one of the five bullets from Servin's unregistered Glock handgun pierced the left side of her head. Servin has maintained he fired only because he felt threatened when he confronted a group at a park about the noise they were making. According to The Chicago Sun Times, Porter said in his ruling: 'Illinois courts have consistently held that when the defendant intends to fire a gun, points it in the general direction of his or her intended victim, and shoots, such conduct is not merely reckless and does not warrant an involuntary-manslaughter instruction, regardless of the defendant's assertion that he or she did not intend to kill anyone. He added: 'The absence of any evidence of reckless conduct renders it unnecessary for this court to consider whether the defendant was justified in his actions.' Porter also cleared Servin, who was off-duty, of reckless discharge of a firearm and reckless conduct. The cop told reporters when he left the courtroom that justice had been served. He said: 'I always maintained it was an accident what occurred to Miss Boyd. 'Miss Boyd and her family, they have my deepest sympathies. Chaos: The judge told loved ones to leave the court before the not gulity verdict was read out - fearing a spate of outbursts. Outside the court Servin (pictured) told reporters at the end of the hearing he has always believed the shooting was an accident . Disgusted: Boyd's supporters (pictured outside court) maintain that she was murdered and insisted the case is 'not over' 'Any reasonable person, any police officer especially would have reacted in the exact same manner that I reacted, and I’m glad to be alive. I saved my life that night. I’m glad that I’m not a police death statistic.' Outside the courtroom Boyd's supporters accused the judge of not having a heart, with one person adding: 'It ain’t over. We all know it’s murder.' In a statement to the Sun-Times, Cook County State’s Attorney Anita Alvarez said he was 'extremely disappointed with the verdict. 'I believe that my office had provided sufficient evidence before the court to not only demonstrate, but also to prove, that Officer Servin’s conduct was clearly reckless in the senseless fatal shooting of Rekia Boyd,' he said. ' 'Justice was denied today for Rekia Boyd and her family, and I extend my deepest sympathies as they struggle to come to terms with this unexpected decision.” The city settled a lawsuit for $4.5 million with Boyd's family in 2013.
