An 11-year-old girl whose disappearance prompted a massive search in 2011 before her body was found in the Connecticut River remains a haunting presence in her rural New Hampshire town.

Celina Cass was last seen hunched over a computer in her family's apartment in West Stewartstown on July 25, 2011. She was reported missing the next day and a trickle of investigators soon turned to scores. They turned the town's elementary school into a barracks and combed the woods and remote roads of this town of fewer than 1,000 people.

Hope turned to grief a week later when her body was recovered.

Three years later, investigators remain silent about the details of Celina's death except to call it a homicide.
