When they arrived, they found the infant, Tyler Burgess, wasn’t breathing. Officers tried to render aid and called for medics to take the child to an area hospital. But, the baby was pronounced dead.

The child’s remains were taken to the medical examiner’s office for an autopsy. On Dec. 23, the medical examiner ruled Tyler’s death was a homicide and that he died from fentanyl poisoning.

On Christmas Day, balloons and stuffed animals memorializing the baby were still on display at the nearby William McAbee Park.

Neighbors remain shocked by Burgess’ death.

“I just pray that the family is safe,” one neighbor said, adding the proximity to the holiday makes it extra painful. “I pray for them, for their loss and hope everything gets better.”

Police have not said how the fentanyl may have gotten into the boy’s system. No arrests have been made in the case.
