Greenwood and Matheny were then taken in for questioning, where she said that he punched and kicked the boy.
She claimed that she told Matheny to stop but did not confirm that he had.
Matheny said that he had been fighting with Neilson but denied causing any serious injuries.
Investigators said that they believe the cleaning products were used to destroy the evidence before Greenwood called the cops.
The pair were charged with criminal homicide and evidence tampering.
Greenwood was also charged with aggravated child neglect. Matheny was charged with aggravated child abuse.
