Thomas Stack's death didn't surprise a lot of people when it happened. He was an alcoholic, and everyone suspected that he accidentally poisoned himself. But once the small town of Farmington heard that Cynthia Galens was actually behind the murder and that she used a large amount of antifreeze to get rid of her husband, everyone was in pure shock. Cynthia was a lovely lady without prior charges, but she did complain a couple of times that Thomas Stack was hurting her in the privacy of her own home. Unable to cope with his mood swings, Cynthia claimed she wanted to make him ill so she could run away from the man himself. But the levels of antifreeze in his system told a different story - that the murder was premeditated and Cynthia could have saved the man's life if she told the truth in the hospital.
