A Dupree woman has been sentenced in U.S. District Court for involuntary manslaughter in the death of an infant she was babysitting.

Amanda Little Elk, 24, was sentenced to 13 months of imprisonment followed by three years of supervised release. She must also pay $9,400 in restitution.

Little Elk was providing day care for 3-month-old Trevor Jon Little Wounded on Dec. 13, 2005, when he died. Court documents said Little Elk "acted in a grossly negligent manner."

When Trevor's mother dropped him off at the day care, he was in a car seat covered with two blankets.

Little Elk put the baby in another room, still wrapped in blankets. When she went to feed him more than four hours later, he was wet with sweat and "did not act normal."

Little Elk did not call emergency help, and when Trevor's father picked him up that evening, Little Elk did not tell him the baby was not acting normally.

Trevor's father took him to the hospital later than evening, and the baby died the next day. An autopsy showed that he died of organ failure caused by being overheated.

Little Elk was sentenced Oct. 16 in Pierre before U.S. District Judge Charles B. Kornmann
