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.

The home where Celina was last seen alive is now gone. It was heavily damaged by fire in December 2013 and was razed.
