A three-judge panel of the First Court of Appeals upheld the conviction and 20-year sentence of Clara Harris.

Harris, 46, was convicted in February 2003 of running over her husband, David Harris, with her Mercedes in the parking lot of the Nassau Bay Hilton hotel after finding him there with his mistress.

The court rejected Harris' complaint that state district Judge Carol Davies improperly excluded two computer-generated accident reconstruction videos.

Harris claimed the videos were essential to her defense that she did not intend to run over her husband.

Harris is in Gatesville, about 35 miles west of Waco, at the Texas Department of Criminal Justice's Mountain View Unit. She works as a Braille typist, translating books for the blind.

She will be eligible for parole after serving 10 years. She faced up to life in prison, but drew a lesser penalty because jurors found that she was driven by "sudden passion" to run down her orthodontist husband.
