SIGNIFICANCE: This murder case had all the elements of a good "whodunit": old money, a marriage gone sour, and arsenic poisoning. The accused husband, a suave Harvard graduate, took the stand in his own defense, almost convincing the jury of his innocence. Then the prosecution brought in a last-minute surprise witness with startling information that sealed Lyon's fate.
An autopsy revealed that when Nancy Dillard Lyon died, she had nearly 100 times the normal amount of arsenic in her body. In other words, the 37-year-old wife, mother, and wealthy Harvard graduate had been poisoned to death. All signs eventually pointed to her adulterous husband, Richard, as her murderer. But was he capable of such a thing?
The first real clue that he was came soon after Richard took Nancy to the emergency room of Dallas's Presbyterian Hospital. For weeks, Nancy had complained of nausea and headaches. Friends noticed her behavior had become increasingly erratic.
