A 52-year-old forensic nurse is charged with first-degree murder in connection with the death of her husband nearly two years after he was found dead at their home in Athens, Ont., about 130 kilometres southwest of Ottawa.

Ontario Provincial Police were called to the couple's Main Street home on Oct. 8, 2009. Sixty-one-year-old Arthur Lane was found dead at the scene. His cause of death has not been released.

Lane had been employed as a labour negotiator with the Ontario Public Service Employees Union, which made him a prominent member of the community. He had stopped working for the union shortly before he died.

One week after Lane's death, family members came forward with information that sparked a homicide investigation. At that point, his wife, Nancy, became a person of interest, according to police.

Police say it's a complicated case. Their investigation even included a police trip to the Dominican Republic where investigators say Lane's wife has ties.

Nancy was arrested on a charge of first-degree murder while she walked to her job at the Brockville Mental Health Centre on Tuesday morning.

She made a brief court appearance in Brockville later that afternoon and was released on a $100,000-bond. Her bail conditions include surrendering her passport, staying in Ontario and having no communication with 67 witnesses.

Nancy's parents attended the court hearing on Tuesday, along with a few of her colleagues who said they were shocked by the murder charge.

Police, though, are standing by their case.

"I do feel we have a solid charge against Nancy Lane," Insp. Rene Bazinet told CTV Ottawa.

The couple has four children together. Nancy will be back in court on Sept. 16.
