A 10-year-old Wisconsin girl has been charged with first-degree homicide in the slaying of a 6-month-old boy, who authorities said was stomped to death at a home-based day care.

The girl, who has not been publicly identified because of her age, was a foster child living with the owner of the day care and her family, Chippewa County District Attorney Wade Newell said Monday during a court hearing. According to the Leader-Telegram in Eau Claire, the girl entered the courtroom wearing a flowery dress and pink shoes.

She cried throughout the hearing, during which she also wore a leather restraint around her waist, the newspaper reported.

The girl is being treated as an adult, but the case could be moved to juvenile court, the Leader-Telegram said. Wisconsin state law requires that all court cases start out in adult court, Newell said.

The girl is being held in a secure detention center, authorities said.

Chippewa County Sheriff Jim Kowalczyk said that the owner of the day care, identified by Wisconsin state licensing records as Amber’s Pals and Playmates in Tilden, called 911 around 4:34 p.m. on Oct. 30 and reported that she’d found the baby bleeding and unresponsive, with obvious injuries to his head. The boy was rushed to St. Joseph’s Hospital in nearby Chippewa Falls, then flown to Gillette Hospital in St. Paul, Minnesota, due to the extent of his injuries.

He died of his injuries Thursday, Kowalczyk said. Chippewa County Sheriff James Kowalczyk says the girl, who lives with foster parents at the home, told investigators the baby’s head hit a footstool, and that she stomped on the baby’s head in panic when it cried.

The infant is one of four children killed in the Chippewa Falls area in the past week.
