The homeowner told police when she went into the bathroom, she saw that the boy’s lips and fingertips were blue and performed CPR. She said she did not see or hear anything prior to seeing the child in the bathroom.

When asked about the bruises and bite marks, Tunstall said he played a “bite game” with the boy, which he did to “calm him down,” court documents said.

However, the Lake County Coroner’s Office reported the boy had died of blunt force trauma to the head and torso/abdomen. The boy had multiple head injuries and a ruptured left lung which had resulted from multiple heavy strikes to his head and body, court reports said.

The examination showed that the injuries happened about four hours after the child last ate with the majority of injuries happening one hour before death.

Police confirmed the mother was not home at the time of the incident after verifying with her employer that she was at work at the time and left the business around 5:46 p.m. Thursday after receiving a call from home.

This information placed Tunstall as the only adult around the children during the incident, court records said.
