The suspect, who has not been identified, pretended to be from the child protective services office when she ordered Fleming who recently gave birth, to come with her.

The young mother was reported missing by her boyfriend and following leads, the traced the suspect to her home but she was not there.

Smelling a foul odour coming from the home, police broke into the home and found the  body of the missing woman. She had been stabbed, covered with bleach, wrapped in plastic and stuffed in a plastic container.

Investigators were still searching the house when the suspect's sister came in with the new born baby.

Police quickly realized that the baby was Serenity and arrested the sister who told them she was only asked to care for the baby while the suspect went to Texas to visit family.

The suspect is now in police custody in a hospital in Texas, where she is under the care of mental health professionals while the child was handed over to the police.
