Celina Cass Found Dead in River, Stepfather Has History of Mental Illness and Criminal Behavior

Celina Cass, an 11-year-old whose body was found by divers in the Connecticut River., will receive an autopsy Tuesday. Law officials said that the girl's death was considered "suspicious" but did not explain why. Celina's death is being treated as a criminal investigation as it has been determined that her body was placed in the river, said New Hampshire senior assistant Attorney General Jane Young .

Celina's stepfather Wendell Noyes, who suffers from schizophrenia, was taken to a hospital after he repeatedly laid face down and rolled around in a driveway. Noyes was released and has re-entered his community as investigators dig through the area where Celina's body was found.

It was revealed last week that Celina's stepfather has a troubled past and several allegations against him for criminal behavior.

Noyes was committed to a hospital against his will in 2003 and diagnosed with schizophrenia, a mental illness characterized by delusions and hallucinations. According to ABC News, court records have shown that Noyes has been arrested for criminal trespass, criminal threatening, hindering apprehension, and violating a restraining order filed by his ex-girlfriend.

Noyes' ex-girlfriend said that he broke into her home, picked up her mattress, and proceeded to slam it into the floor. She also said that Noyes threatened to throw her down a flight of stairs.

Noyes was deemed incompetent to stand trial by a judge due to his mental illness. Judge Richard Hampe said that Noyes is "a potentially serious likelihood of danger to himself and others."

Noyes has not yet been named a suspect in Celina's death.

Adam Laro, Celina's biological father, told Fox News that the girl was "shy but very friendly" and that she would not leave alone at night. "I can't picture why she would leave at night," said Laro. Laro was in the hospital when Celina was last seen using her computer in her bedroom.
