Court testimony revealed Wednesday that the death of a five-year-old Tennessee boy followed punishments that included eating cigarette butts and drinking dish soap.
Rhea County Sheriff's Detective Rocky Potter testified during a preliminary court hearing for the boy's mother, 29-year-old Jessica Robbins, and her boyfriend, 22-year-old Bradley Adcox.
Both are charged with murder and aggravated child abuse in the August 30 death of Landon Robbins.
The boy was found dead in the family's home in Spring City, about 60 miles north of Chattanooga.
The couple had been charged initially with abuse and neglect after they told officers the boy received his injuries in a fall.
The charges were upgraded after an autopsy that showed the boy suffered bruising, blunt force trauma and contusions all over his head and face, as well as a bite mark on his back.
The autopsy also found a cigarette butt in his stomach, according to the Chattanooga Times Free Press.
Judge Jimmy McKenzie bound the case over to the grand jury and declined to set bond.
