Prosecutors in the case of a former nurse accused of killing her husband with an overdose of a paralyzing drug plan to show jurors video of her kissing her lover outside a motel room.

That revelation was part of the prosecutor's opening argument, which got under way Monday morning in Charleston.

Thirty-five-year-old Michelle Michael of Morgantown is charged with killing her husband, James, in 2005, 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 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.
