WEST STEWARTSTOWN, N.H., Aug. 2 (UPI) -- The autopsy on Celina Cass, the 11-year-old New Hampshire girl whose body was pulled from the Vermont River, was inconclusive, officials said Tuesday.
Authorities said medical examiners who performed the autopsy had yet to determine how the girl died and were awaiting "toxicology results and further investigation," The Boston Globe reported.
"The cause and manner are still pending," Assistant State Attorney General Jane E. Young told reporters late in the day.
Young declined to comment on what the autopsy found or to discuss the condition of the body, though investigators had concluded Celina's death was suspicious after seeing her body when it was recovered from the river, the Globe said.
"We are doing everything we can to have more definitive answers," she said.
Young would not say whether police had identified any suspects or persons-of-interest, though she said there was no need for the public to have "heightened alarm."
As authorities tried to determine how Celina died, it emerged that her stepfather has a history of crime and insanity.
The girl's body was found Monday in the Connecticut River near the home in West Stewartstown, N.H., where she lived with her mother, sister and stepfather, Wendell Noyes.
Friends and neighbors held a candlelight vigil in the village near the Canadian border Monday night, ABC News reported. Walter Laro, Celina's grandfather, thanked investigators and the media for their work solving her disappearance.
Senior Assistant State's Attorney General Jane Young said the case is now being handled as a criminal investigation but named no suspect. Celina was last seen at home July 25.
Noyes, 47, who was rushed to a hospital Monday after behaving strangely, was involuntarily committed to a mental hospital in 2003, court records show.
He was arrested after invading an ex-girlfriend's home and threatening her in violation of a protective order but found incompetent to stand trial. A forensic examiner found him to be a paranoid schizophrenic and a threat to others.
