A man is facing first-degree murder charges in the death of a 2-year-old child authorities say was discovered unresponsive with head trauma in a Denham Springs apartment Friday.

Police officers found the injured toddler after they were dispatched to 2455 Florida Ave. S.W., according to a news release from the Denham Springs Police Department. The young girl was taken to Our Lady of the Lake Regional Medical Center in critical condition. The child succumbed to her injuries Monday.

The child's mother and her fiancé were initially arrested on felony cruelty to juveniles, the news release said. Those charges were upgraded after the toddler died.

The mother, Kelsey Barth, 23, was booked into Livingston Parish Jail on a count of negligent homicide. Her bond is set at $75,500. Her fiancé, Shane Posey, 22, was booked on first-degree murder with no bond, according to court records.
