The other two girls were found in a metal drum in the same area in 2000.Watch full video of announcement."They were killed at the same time, and this time period has now been narrowed down to sometime between 1980 and 1984," Agati said.Private labs, the National Center for Missing and Exploited Children and the Florida Institute of Forensic Anthropology conducted tests on the remains. Agati said new scientific techniques allowed investigators to learn new information about the victims, who have never been identified."We are able to draw new, very detailed maps of where our victims lived, where they were raised and new timelines for their movements immediately prior to their death," Agati said.The National Center for Missing and Exploited Children said this is the only case it has ever assisted with four unidentified victims.Investigators tested isotopes in the victims' bones, hair and teeth and determined that the adult, the oldest child and youngest child likely lived in an area close to the Atlantic Coast. They likely lived anywhere in an area stretching from Pennsylvania through Maine, but it's possible they lived in other parts of the country, Agati said.The middle child likely spent her childhood further inland, most likely further north in an area that includes a small part of northern New Hampshire. She may also have lived as far west as Minnesota.36499414Investigators said that child likely spent most of her life away from the other three, but in the last several weeks or months before she died, all four victims were together or near each other.Isotopes are forms of elements that may decay over time in predictable ways. They are naturally in the environment and are incorporated into bones, hair and teeth. Forensic experts can measure the presence of isotopes and narrow down where a person lived and even what they ate.All the victims were described as Caucasian. Agati said the adult was a woman likely in her mid-20s with wavy, light brown hair. She had three fillings, and she had to have three of her teeth removed.The oldest child was likely 9 or 10 years old when she died. She had light brown or blond hair. The middle child was likely 3 or 4 years old when she died and had brown, wavy hair. She also had an overbite that might have been noticeable.The youngest child was likely 2 or 3 years old when she died. She had light brown or blond, wavy hair. She had a large gap between her upper two front teeth that would have been noticeable when she smiled."The unanswered questions need to be answered," Agati said. "So, it has been frustrating, but it's not a case worth giving up on."Anyone with information is asked to call the National Center for Missing and Exploited Children at 1-800-THE-LOST, or contact the state cold case unit at coldcaseunit@dos.nh.gov.
