Bear Brook Jane Doe was a girl found in 2000 in Bear Brook State Park in Allenstown, New Hampshire. She is believed to have died in 1985 or prior, as the first two victims were located that year.
The victim was found inside of a metal drum with a younger female.
This female in particular is somewhat puzzling, as she was not maternally related to the three others. It is possible that she was related paternally or possibly a friend of the two other children, but authorities believe her and the other three victims most likely are biologically linked. After advanced forensic testings, it was revealed that she lived in a different forensic area than the other three victims, possibly in a northern and inland location north of New Hampshire, Vermont, upstate New York, or far west Michigan, Minnesota, Wisconsin,
She is believed to be of Native American ancestry, as her dentition suggests.
In 2017 the investigators revealed information that the girl's biological father had been identified as Robert T. Evans (also known by the name Bob Evans and several other aliases), who's known as a former boyfriend of missing Manchester woman, Denise Beaudin and convicted murderer. He died in prison in 2010, and the police now believes that the girl's biological mother - never recovered - probably also fell victim to him. In August 2017, "Robert Evans" had been identified as Terrence Rasmussen, who left his family in Arizona around 1974 and was never seen again by his relatives.
