An autopsy for Celina Cass, the missing New Hampshire girl, is schedule for Tuesday and could reveal the cause of death.

The body of the 11-year-old girl was found in the Connecticut River in Stewartstown on Monday morning leaving a family in mourning.

Senior Assistant Attorney General Jane E. Young held a news conference on Monday evening and said Fish and Game divers found the body around 10:30 a.m., about one-quarter of a mile from the girl's home and recovered it about 5 p.m., according to reports.

"We are treating her death as a suspicious death at this time," Young said, as reported by the Nashua Telegraph.

The fifth-grader was last seen in her bedroom on the computer at her Stewartstown home on the night of July 25. She lived with her mother, stepfather and 13-year-old sister. She was missing for about a week before her body was found.

An extensive search to include the FBI was launched to find Cass and bring her home safely. But divers found her near a hydroelectric dam that spans the Connecticut River, which is between her hometown and Canaan, Vt.

A $25,000 reward was being offered for information leading to her location and prosecution for anyone involved in her disappearance. Cass's father had pleaded for her to come home.

"We have brought Celina home, obviously not the way we wanted to bring her home," Young said with her voice cracking with emotion during a press conference on Monday, according to Fox News.

The Associated Press has reported that authorities are classifying the death as suspicious.""
