STEWARTSTOWN — One week after an 11-year-old seemingly vanished from the home she shared with her mother and stepfather, the body of Celina Cass was recovered Monday from the Connecticut River, about a half-mile from where she lived. “We brought Celina home,” said New Hampshire Senior Assistant Attorney General Jane Young, her voice cracking at times during a media briefing Monday night, “obviously not the way we wanted to bring her home.” Young said Cass' death is being treated as suspicious and a criminal investigation is under way, “based on what we have seen visually.”
