A detective testified Wednesday that a Rhea county woman and her boyfriend punished her son by making him drink dishwasher liquid and eat cigarette butts.
Jessica Robbins and Bradley Adcox are charged with first-degree murder and aggravated child abuse and neglect in the death of her son, 5-year-old Landon Robbins.
The boy died from multiple blunt force trauma, according to the autopsy report.
Rhea County Sheriff Department Detective Rocky Potter said the boy was punished for not going to bed at night.
He said they also whipped the boy often and Adcox would bite him.
The detective said the victim had numerous bruises across his forehead and scalp as well as two black eyes and a small scratch on his lower chin.
The boy was found dead on Aug. 30 in the couple's camper home on Cawood Road.
The case was forwarded to the Grand Jury.
The pair remain in the Rhea County Jail without bond.
