Final Bear Brook victim identified as Rea Rasmussen, closing a 40-year-old case but leaving questions about her mother.

Her tiny body was found stuffed in a barrel in the New Hampshire woods, one of four victims of the so-called Chameleon Killer. No one knew who she was, where she was from or how she got there, until now.

A LITTLE girl has finally been named 25 years after she was found dead in a barrel at a New Hampshire state park. The fourth and final victim of serial killer Terry Rasmussen has been identified

The mystery, one of the first major cases to highlight genetic genealogy in solving crimes, began in 1985 when a hunter discovered the bodies of a woman and 9-year-old girl in a barrel at Bear Brook State Park in Allenstown. In 2000, an investigator found another barrel nearby containing the body of two more girls estimated to be ages 2 and 3.

New Hampshire authorities used DNA genealogy to identify Rea Rasmussen as the last unknown victim in a 40-year serial killer case.

New Hampshire State Police say the final unidentified victim in the 1985/2000 Allenstown homicide case -- or the Bear Brook Murders -- has been identified.

After identifying the final victim of the Bear Brook murders as Rea Rasmussen, investigators with the New Hampshire Attorney General's Office answer questions at a news conference on Monday. See the full news conference,
