A Michigan judge has ruled that Jack Kevorkian must stand trial for assisting two suicides in 1991. Kevorkian faces up to five years in prison and a $10,000 fine in the deaths of Marjorie Wantz and Sherry Miller. Miller, 48, who had multiple sclerosis, died after inhaling carbon monoxide through a mask. Wantz, who suffered from chronic pelvic pain, died after using a Kevorkian device that injected lethal drugs into her system. The trial is scheduled to begin April 1. Kevorkian was already scheduled to stand trial beginning February 12 for assisting two other suicides in Michigan.
