Prosecution, defense make final pitch in Georgia day care murder trial March 14, 2012 -- Updated 0025 GMT (0825 HKT) Dunwoody, Georgia, murder defendant Hemy Neuman has pursued an insanity defense. Hemy Neuman is charged with murder in the 2010 death of Rusty Sneiderman He has pleaded not guilty by reason of insanity A prosecutor tells jurors to use their common sense Atlanta (CNN) -- The defense and prosecution in the trial of a man accused of killing another man outside a Georgia day care center delivered their closing arguments on Tuesday. Hemy Neuman is charged with murder in the death of Russell "Rusty" Sneiderman in November 2010. Sneiderman was shot multiple times in the parking lot of Dunwoody Prep in suburban Atlanta after dropping off his son, in what police described as an apparent "cold and calculated murder." Neuman has pleaded not guilty by reason of insanity, and his defense on Tuesday also implicated the victim's wife in the murder. Andrea Sneiderman has not been charged. "The gun in this case was in Hemy's hand, but the trigger -- I respectfully suggest -- was pulled by Andrea Sneiderman," defense attorney Doug Peters told the jury. At the time of the shooting, Neuman was Andrea Sneiderman's supervisor at work and both the defense and prosecution have accused her of having an affair with the defendant, CNN affiliate WSB reported. She denied the affair on the stand, it said. The prosecution, meanwhile, argued that Neuman is making up the insanity defense and urged jurors to use their common sense. You are expected to use your common sense. You walk in this courtroom, not in an intellectual bubble, but you bring your life experiences and your common sense with you and you apply it to determine whether or not somebody is malingering or telling the truth," DeKalb County District Attorney Robert James said. Sneiderman's killing shocked and perplexed many in the community. The married father of two "was murdered. No one should ever have to face that," said his brother Steven Sneiderman at the time. Our family has been devastated. My niece and nephew will never know their father. My sister-in-law has had an entire lifetime of dreams ripped from her. Our whole family has lost its brightest light, and we don't know why. Rusty Sneiderman, 36, was a Cleveland, Ohio, native, a Harvard MBA graduate, and an active volunteer with the Georgia chapter of the Cystic Fibrosis Foundation, WSB reported.
