It's been four years since Celina Cass was last seen hunched over a computer in her family's New Hampshire apartment.
The 11-year-old was last seen July 25 in West Stewartstown. A week later, her body was found in the Connecticut River near a dam.
Four years later, no one has been charged with her death, which investigators have called a homicide. It is still a haunting presence in the small, rural, town.
The attorney general's office says it is still investigating the case.
