(KNZA)--A St. Joseph woman has pleaded guilty to an endangerment charge in the death of her one-month-old daughter last August.

The St. Joseph News Press reports 22-year Doris Koon entered the plea Monday in Buchanan County Circuit Court.

Sentencing is set for May 9th.

Koon was charged after she spent three hours Aug. 21 walking the halls at Mosaic Life Care in St. Joseph with the lifeless baby.  A security guard at the hospital found the mother with her child's body.

In court Monday, a tearful Koon told the judge that on the night before the child's death she consumed alcohol and then co-slept with the baby. When she awoke, she found the baby had died.

Koon remains in the  Buchanan County Jail.
