FORT WORTH, Texas —  An Arlington woman who caused her lover's shooting death by falsely crying rape was found guilty Friday of involuntary manslaughter.

Tracy Denise Roberson, 37, cried slightly when the verdict was announced after jurors had deliberated for more than a day. The punishment phase was set for Monday, and she faces two to 20 years in prison.

In late 2006, Darrell Roberson came home from a late-night card game to find his scantily clad wife with another man in a pickup truck in the driveway. Tracy Roberson was with her lover but cried rape, and her husband fired four shots into the truck as Devin LaSalle was driving off, killing him.

Darrell Roberson initially was arrested, but the murder charge later was dropped and a grand jury indicted Tracy Roberson instead.

During her three-day trial, defense attorneys called no witnesses but blamed LaSalle's death on Darrell Roberson's jealousy and rage.

But prosecutors placed all the blame on Tracy Roberson, showing evidence of the affair with LaSalle, 32, and a text message in which she invited him to her house that evening.
