Teachers: Boy’s Appearance Changed Dramatically, and He Would Hoard Food

The boy’s alleged plight came to authorities’ attention when the DHS asked police on Jan. 24 to help them investigate a hotline report stating that a boy was being handcuffed to furniture and being denied food as punishment at home, according to an arrest report, Arkansas Online reports.

Teachers and staff members at the Owl Creek School told detectives the boy’s appearance had changed dramatically since November. They said he had become “very thin,” the report states, according to local station KATV.

“His eyes had become sunken, as had his cheeks, and his skin tone changed,” the report states, citing staff members’ statements.

He was also seen bleeding through his shirt and said his legs hurt when he walked, the report continues.

He would often hoard food, steal food from other students and ask for extra food and would cry if he didn’t get any, the report states.

The child also suffered from incontinence at school and often smelled of urine, staff members told detectives, according to the report.

Police questioned Miranda’s 17-year-old daughter, who gave investigators an audio recording of Miranda disciplining the boy because he stole candy, FOX 16 reports.

She allegedly threatened him, saying “I’ll cut you,” and allegedly told him she would abandon him in the cold and have him arrested for stealing candy, the report states.

After hearing the recording, police arrested the couple when they arrived to pick up the children from school, the report states.
