SIOUX FALLS, S.D. (AP) — Sioux Falls police say an arrest warrant has been issued for a woman in the death of her 4-month-old baby.

The 22-year-old mother is wanted for abuse or cruelty to a minor, among other charges. Police spokesman Sam Clemens says officers have not been able to locate the woman.

Police responded to a home Wednesday on a report of an unresponsive infant. The baby girl was found unconscious on a bed, was taken to the hospital and pronounced dead.

The Argus Leader says an affidavit says the mother told police she drank tequila until she passed out the night before and woke up the next morning to find the child unconscious. The document says an autopsy conducted on the baby found the cause of death to be undetermined.
