'I Don't Want No Casey Anthony,' Grandfather of 11-Year-Old Celina Cass Says

The grandfather of 11-year-old Celina Cass, whose death has been ruled "suspicious," pleaded with police to solve the case and said he hopes it doesn't leave unanswered questions like in the Casey Anthony murder trial.

"I just hope justice is brought and whoever’s responsible gets the max because that little girl didn’t deserve that," Celina's grandfather, Wally Laro, told the Boston Herald Wednesday. "I don’t want no Casey Anthony."

Casey Anthony was acquitted last month of murdering her 2-year-old daughter, Caylee, whose remains were found near her Orlando home six months after she was reported missing in 2008. No cause of death was ever determined and no suspects -- besides Anthony -- have been named by authorities.

Celina's body was found Monday in the Connecticut River not far from the Stewartstown, N.H., home she shared with her mother, stepfather and 13-year-old sister. Investigators have ruled her death "suspicious," and said Tuesday that they are waiting for further toxicology reports to determine how she died.

The fifth-grader, who had been missing for a week, was last seen the night of July 25 in her bedroom and on her computer.

Authorities on Wednesday took away a silver pickup truck parked near the family's home for inspection.

On the morning Celina's body was found, the girl's stepfather, Wendell Noyes, was taken by ambulance to a nearby hospital. The reason for his hospitalization it not yet known. Noyes reportedly has a history of schizophrenia.

Meanwhile, Jeanine Brady, a family friend and the employer of Celina's mother, says the girl's body has been turned over to the family and a service is being planned. Brady won't say where or when the service would be held. She says it will be private.

Young would not go into details about the initial autopsy results but said, "both the cause and manner of death are pending."

After an extensive search for the child -- which included help from the FBI -- divers discovered her body Monday morning near a hydroelectric dam that spans the Connecticut River between her hometown and Canaan, Vt., not far from the Canadian border.

"We have made no determination on where her body was eventually put in the river," Young said on Monday.

Authorities have said there was no sign of a struggle inside the home, and there was no indication the girl ran away or that someone took her.

"Based on what we have seen visually, we are treating it as suspicious," Young said.

Celina's father, Adam Laro, had described his daughter to Fox News as "shy but very friendly" and said he can't imagine she'd leave on her own.

"I can't picture why she would leave at night," said Laro, who was in the hospital when Celina was last seen. "She seemed to be happy where she was."

Young told FoxNews.com last week that authorities did not issue an Amber Alert for Celina because the case did not meet the criteria for one. Amber Alerts usually require a description of a vehicle or person the child was last with, Young said.

The girl's close-knit community held a candlelight vigil for the girl on Monday, just hours after her body was pulled from the river, the Boston Herald reports.

"She was a dream student," Jennifer Mathieu, who taught Celina in second and third grade, said of the girl. "If one of her friends was in a bad mood, she was the first to go over and try to cheer them up. She wanted everyone to be happy."
