SIOUX FALLS, S.D. (AP) — A Pine Ridge couple have been sentenced after pleading guilty to involuntary manslaughter in the death of their five-month-old son.

U.S. Attorney Brendan Johnson says 25-year-old Whitnee Eagle and 31-year-old Abraham Silas Red Cloud were each sentenced in federal court to nine months custody and three years of supervised release.

Eagle and Red Cloud were indicted for involuntary manslaughter and felony child abuse and neglect last year, but pleaded guilty to involuntary manslaughter in March.

Johnson says Eagle and Red Cloud had been drinking in June last year when they rolled over onto their son who was sleeping in the same bed with them. The boy suffocated.
