A prosecutor says an East Texas nurse accused of killing five kidney dialysis patients by injecting them with toxic bleach violated the trust of a noble profession.

Angelina County District Attorney Clyde Herrington laid out the accusations Monday during opening statements in the trial of Kimberly Saenz (synz). The 38-year-old nurse is charged with capital murder in the April 2008 deaths and aggravated assault in the case of five other patients injured at the DaVita Dialysis clinic in Lufkin.

Prosecutors say they'll seek the death penalty if she's convicted.

Saenz stood at the defense table Monday holding her hands behind her back as a prosecutor read the six-count indictment against her.

Defense attorney Ryan Deaton responded, "Not guilty, your honor," as the judge asked for a plea after each count.
