Murder Trial's Focus on Victim's Widow At the murder trial of the man accused of killing her husband, Andrea Sneiderman has faced some tough questioning of her own. Last week, prosecutors and defense attorneys grilled her for four days about her husband Russell's November 2010 shooting death. They've suggested she was involved in an affair with his killer, that she knew details about his death suspiciously early and that she tried to protect the man prosecutors say gunned down Russell Sneiderman after he dropped off his toddler at a suburban Atlanta day-care center. Although Andrea Sneiderman hasn't been charged with a crime, she has been front and center at the murder trial of her ex-boss, Hemy Neuman. He claims he was insane when he killed Russell Sneiderman, asserting that an angel who looked like Olivia Newton-John ordered him to carry out the shooting. Defense attorneys say Neuman fell so hopelessly in love with Andrea Sneiderman, whom he supervised at General Electric, that he believed he was the father of her two children and that the only way to protect them was to kill Russell Sneiderman. Neuman, who has quietly watched the proceedings since Tuesday, faces life in prison if convicted. In testimony and through her attorney, Andrea Sneiderman has denied allegations she was involved in an illicit relationship with Neuman, who she considered a family friend. She said she was the victim of "masterful manipulation" from a stalker who weaseled his way into her life only to ambush her husband when she refused Neuman's advances. Her denials haven't stopped both sides from targeting her. Her testimony could play a key role for prosecutors who seek to prove her husband's killing was a carefully planned killing and defense attorneys who may argue that Neuman's love for Andrea Sneiderman ultimately drove him insane. She's responded with occasional hostility and emotion to the questions from both sides. During breaks, she gave tearful hugs to family members, who sat conspicuously apart from Russell Sneiderman relatives, and once gave a long embrace to a family friend called to testify. A judge put an end to the behavior Friday when he barred her from the courtroom after prosecutors accused her of improperly contacting a witness. The trial has attracted international attention because of the brazenness of the slaying, the backgrounds of the suspect and victim and the unlikely community where it took place. Russell Sneiderman, a Harvard-trained entrepreneur, was killed shortly after dropping off the couple's 2-year-old son at the center in Dunwoody, a wealthy suburb north of Atlanta. A bearded man in a hoodie fired four shots and then hopped into a silver minivan and sped away. Neuman, a Georgia Tech graduate and father of three, was arrested about six weeks later after prosecutors learned he had rented a similar vehicle before the shooting. Investigators believe he meticulously planned Russell's killing and that he didn't show signs of emotional distress in the weeks leading up to the killing. But defense attorneys argue that Neuman was suffering from delusions and believed he was the father of Andrea's two young children. When the trial resumes Monday, it's a safe bet that attorneys will refocus on whether Andrea Sneiderman knew about plans for the shooting before it took place and worked to protect her ex-boss during the investigation.
