Opening statements are expected to start Monday in the trial of a former nurse accused of killing her husband in 2005.

Thirty-five-year-old Michelle Michael of Morgantown is charged with overdosing her husband, James, with a paralyzing drug, then setting fire to their home to cover up the crime.

Prosecutors say Michael admitted to having an affair with Robert Teets, who was a delivery driver at her husband's business, Mountaineer Home Medical.

Teets is not considered to be co-conspirator and he may be called to testify. Michael's attorneys unsuccessfully sought to have references to the affair banned, claiming it was unrelated to the case.

The trial was moved from Morgantown to Charleston because of pretrial publicity.
