Prosecutors have charged a southeastern Kansas woman with first-degree murder in the death of her 18-month-old daughter.

KAKE-TV reports 23-year-old Alyssa Haag made a first appearance Wednesday in Butler County District Court. The El Dorado woman remains held on $500,000 bond, with a preliminary hearing scheduled May 9.

The charge stems from what investigators believe was the abuse death of Jayla Haag. The toddler died last week at a Wichita hospital, where she was treated for injuries the mother said were caused when the girl fell down the stairs.

Haag did not yet have a lawyer. No phone number was listed for her in El Dorado.
