I don't know if this is the doctor that Gozgals is thinking about. This case was back and forth in the news for years. Kay Sybers died in 1991 in Panama City, Fl. where her husband was the medical examiner, and was involved with another woman; he married her soon after Kay's death. It was never definitively determined what he injected Kay with. It took years to get him charged. He only spent 3 years in prison after his first conviction in 2001. When that was overturned he and the new wife moved to Canada. A new trial was getting ready to start when he pleaded guilty to manslaughter in 2003.

"Some fervently believe that Bill Sybers, now 70 and suffering from a variety of illnesses, a man who had battled lung and bladder cancer as well as diabetes and heart problems, is a cold-blooded killer. Perhaps even his youngest son was one of them. He killed himself in 1993, and according to police, he did it after telling a girlfriend that he could not stand to live with the thought that his father might be a killer.
But there are others, among them Kay Sybers' own family in Iowa and her two surviving children, who believe that he is an innocent man who has been hounded and jailed and harassed and humiliated by a judicial system in Florida.
In the years since Kay Sybers' death, Bill Sybers has been tried and convicted for her murder, though a jury decided not to recommend the death penalty, sparing his life and sparing him the irony of dying from the same lethal cocktail of drugs that prosecutors insisted he used on his wife.
In early 2003, in a decision that thrust the case again into the headlines, Sybers' conviction was set aside by an appeals court, which ruled, among other things, that the science prosecutors used to convict him was perhaps flawed and was certainly unproven.
A few months ago, the ailing doctor pleaded guilty, not to murder, but to manslaughter in connection with her death.
But even that plea has not ended the controversy or the mystery. Through his attorney, the noted criminal lawyer Nathaniel Dershowitz, Sybers maintains that he had nothing to do with his wife's death, and that he pleaded guilty only to end what he sees as years of persecution by an overzealous prosecutor."

"Sybers agreed to plead guilty to manslaughter. He was fined more than $500,000 and sentenced to ten years.
Although he had spent less than three years behind bars on his original conviction, he was released."
