Watkins had been ordered to have psychiatric treatment and been found competent to stand trial. Her attorneys say she was diagnosed with postpartum psychosis, which can be characterized by depression, confusion and hallucinations beginning shortly after childbirth.

Police found the decapitated baby on the kitchen counter in the home of an aunt who was caring for her. The baby had been stabbed multiple times.

Authorities say Watkins appeared to have serious mental issues when they found her covered in blood in bed at the aunt’s home.
