The girl was just 10 years old when she allegedly dropped the baby boy on Oct. 30 of last year. According to prosecutors, the child hit his head and began crying, at which point the girl started panicking and stomped on the baby to quiet him. The injuries proved to be fatal and the little boy was pronounced dead two days later, on Nov. 1.
The girl, now 11, is not being identified because of her age but was charged as an adult with first-degree homicide with intent, a felony, making her one of the youngest ever to be charged with such a serious crime.
Now, her mother is speaking out for the first time.
"There is no way it was done in any type of intentional way," she told Inside Edition. Asked if she remembered anything her daughter told her, the mom replied, "That it was, just that it was an accident. And you know what? I believe my daughter."
The girl is currently being held at the adult Winnebago Mental Health Institute, which is about four hours from her home.
"She's the youngest person there," her mother said. "She's 11 years old with women 40 years old and over."
She added: "She wants to go home." The mother is raising money on GoFundMe to try to bring her daughter home.
