Jurors at the murder trial of the Plano woman accused of killing a two-year-old girl heard the stories she gave police during her interrogation.

Grace Ford, 2, was suffocated with duct tape over her mouth. Her father's ex-fiance, Melinda Muniz, is charged with capital murder.

The toddler was found unconscious during what police call a staged home invasion. Grace died several days later at a hospital. Muniz told investigators a man broke in, beat her and sexually assaulted her. Police have said her story didn't add up.

Thursday's testimony was primarily from a detective who questioned Muniz for hours before and after her arrest. Jurors got to watch the video recordings of the interrogation.

Videotaped interviews screened in court showed Muniz sobbing and admitting she staged the scene while panicking after she found Grace unresponsive. She said the toddler somehow put duct tape over her own face.

At one point the detective said Muniz agreed to a polygraph but later said she couldn't because she'd developed amnesia.

The prosecution said it will most likely rest its case on Friday, which will then allow the defense to begin its case.
