Nancy Lyon
}} Nancy Cooke Dillard Lyon (6th August 1953 – 14 January 1991) was an American woman who was poisoned with Arsenic and killed by her husband Richard Lyon. She was about to testify against her former boss in a trial for an Embezzlement charge but was poisoned before she could do so.
Death[edit]
On a January night in 1991, she has severe sickness which showed symptoms that included vomiting and severe stomach pains. Richard took her to the hospital but the doctors couldn't find what had caused this severe sickness. Her condition deteriorated overtime and her organs started to fail. She passed away on the 14th of January 1991. A nurse who was taking care of Lyon said to her husband who was a homicide detective that she looked like she had been poisoned.
Investigation[edit]
The doctors who took care of Lyon made 2 phone calls to the Dallas County Police and to medical examiner Jeffrey Barnard listing that her death looked like a homicide. The medical examiner did not find any signs of a disease in her system but found lethal doses of Arsenic in her system at her autopsy which later found that she had ingested small doses every week starting from four months before her death. A receipt found by the police showed that she purchased Arsenic a few months earlier. Her husband claimed she purchased the poison to get rid of some fire ants in her yard. The police then found out she had been suffering from depression for the past year after finding out Richard had an affair with another woman. Then the police found a shocking note which Nancy wrote accusing her older brother Bill of sexually abusing her as a child. To determine who wrote the note, police sent it to Hartford Kittel who examined the note by taking samples of Richard and Nancy's known writing. He concluded that Richard was the one who wrote that to try and cover up his crime.
Trial[edit]
Richard Lyon's trial took place on December 2nd, 1991 and ended on January 19, 1992. He was convicted of murder and sentenced to life in prison.
