Killed: Police believe Samantha Fleming, 23 (left), was lured from her home by a woman pretending to be a social worker, so that the woman could murder her and steal Fleming's three-week-old baby, Serenity (right) Found dead: Fleming went missing from her home in Anderson, Indiana, on April 5. Her body was found Friday at a house 180 miles in Gary. The woman who lives at the property is the suspect in the case . The suspect is said to have known a lot of personal information about Fleming and successfully posed as a case worker, leading Fleming to believe she had to attend a court hearing. Fleming was reported missing by her boyfriend. Police were led to Gary after Fleming's cell phone signal was picked up in the city, where the young mother's wallet was also found near an apartment block. Police followed other leads to the suspect's home, but the woman wasn't there. Investigators said they smelt a foul odor coming from the small one-story house. Inside they found the body of a young woman that had been stabbed, covered in bleach, wrapped in plastic and stuffed in a plastic tub. As officers searched the home, the suspect's sister came by. She had a baby with her and was had come by to pick up some things. Police quickly realized the baby was Serenity. Scene: The body of Samantha Fleming was found stabbed, doused in bleach and wrapped in plastic inside this home at 1987 Cleveland St., in Gary, on April 17 . The sister told police the suspect had asked her to care for the baby and had gone to visit their mother in Texas. The suspect is now said to be in police custody at a Texas hospital, where is she is under mental health care. The infant was handed over to police by the sister, according to the Chicago Tribune. Police have not released the name of the suspect and no charges have been filed. Lt. Thomas Pawlak told The Tribune that the suspect's house had been fitted out with a nursery. 'It appears that she had been planning this,' Pawlak told the newspaper. 'There was everything you would buy for a new baby. A crib, changing table, diaper bag, carrier, new clothes.' A neighbor told the paper the suspect said she was pregnant with twins. The neighbor said around Easter the suspect said one of the twins had died but that she had given birth, only the child was still in hospital with jaundice. New mom: Fleming went missing just three weeks after giving birth to her daughter, Serenity . Safe: Serenity was found in the custody of the suspect's sister. The baby will soon be returned to relatives in Anderson following the tragic death of her mother . When the neighbor eventually saw the woman with the child, she said she found the baby to be 'lighter-skinned' than she expected. The woman also had a bandage on her hand. The alleged kidnapper asked her neighbor to watch her house because she was going out of town. Just days before the woman left, the neighbor said she saw her going back and forth from her house to her garage and carrying small plastic grocery bags. The neighbor said they had been texting regularly since the woman left. But when she texted the alleged kidnapper after she saw police enter her home on Friday, the messages stopped. Pawlak believes the alleged kidnapper was very familiar with Fleming, and they are trying to work out how. The woman is not believed to be affiliated with Child Protective Services in any way. 'She knew a lot about this mother,' he said. 'Enough to convince her she was with CPS.'
