SACRAMENTO, Calif. (AP) – A jury has convicted a California woman of first-degree murder in the microwave oven death of her 1-month-old daughter.

The Sacramento County District Attorney’s Office says jurors Friday also convicted 34-year-old Ka Yang of assault on a child causing death. She faces 26 years to life in prison and is scheduled to be sentenced in December.

Prosecutors say Yang put her daughter, Mirabelle Thao-Lo, in the microwave at her Sacramento-area home for 2 and ½ to 5 minutes in March 2011. The 34-year-old Yang’s attorney, Linda Parisi, said her client was in the midst of a seizure and unknowingly put the girl in the microwave.

The girl suffered what authorities said were extensive thermal injuries.
