Marco Demma, a homicide detective from New Orleans, was faced with a dilemma. He was working on a 1986 murder case-- an unidentified woman was murdered and dumped into Louisiana's Lake Pontchatrain. Fishermen had found her body three days later. By that time, there wasn't enough evidence left to ID her body and she was buried in an unmarked grave at Potters Field. But in 2003, Detective Marco got a break. Lisa Sexton, a woman from Ohio, had gone missing around the time of the murder. The two women shared similar characteristics; they were the same age, height and weight. Could they be one and the same person?
Detective Marco wanted answers. Lisa Sexton's mother gave police medical and dental records for her missing daughter. But, in 1986, neither DNA nor dental records were compiled for Jane Doe. So Marco employed the help of the "Bone Lady."
Detective Marco had worked with Mary Manhein, or the "Bone Lady", before to crack what, at first glance, would seem like unsolvable crimes. Mary Manhein is an anthropologist who specializes in the human skeleton. She is founder of the FACES (Forensic Anthropology and Computer Enhancement Services) lab at Louisiana State University. From her assessment of skeletal remains, Mary can create a crime victim profile law enforcement agents can use. She can make out the persons age, gender, and height merely from looking at their bones. Furthermore, "Bone Lady" can recognize whether the victim underwent trauma and the amount of time lapsed since death.
