The doctor added that it did not appear the baby died as the result of an assault.
"Lundstrom alleged she did not have any knowledge of what had possibly occurred in the room while she was gone," the police report states.
She also told investigators her 18-year-old daughter was home during that time; However, the teen told officers she had gone to a park with her boyfriend, and was not at the house.
Lundstrom faces charges of first-degree involuntary manslaughter, first-degree endangering the welfare of a child resulting in death, and eight counts of first-degree endangering the welfare of a child.
She is also charged with operating a child care facility without a license; in the state of Missouri, a license is not needed to operate a daycare — as long as you are only looking after six kids or less.
