NH COLD CASE UPDATE: New info and sketch of victims; woman and 3 children DO YOU KNOW THEM?
*They were killed at the same time, and this time period has now been narrowed down to sometime between 1980 and 1984.
*The woman was likely the mother of the two girls, he said. The middle child was not maternally related to the others, but it's possible she was a half-sister of the other girls or a paternally related cousin.
*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.
*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.
* Investigators 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.
