(WPXI) – The case against a mother and father accused of locking their 6-year-old daughter naked in a dog cage, beating her and denying her food will head to trial. Jacob Weight and Mimi Frost had their preliminary hearing in magistrate court Tuesday afternoon. The district attorney called on two firefighters who responded to the home in January when their child went unresponsive, two state troopers, a county Children and Youth Services case worker, and Weight and Frost’s nephew.
