WEST STEWARTSTOWN, N.H. – The stepfather of an 11-year-old girl whose body was pulled from the Connecticut River in August says he had nothing to do with her disappearance and death.

Wendell Noyes told WMUR-TV that he discovered that Celina Cass was missing the morning after she was last seen on the family computer on July 25.

“When I got up that morning, there was, well, she usually sleeps on the couch,” Noyes said Monday.

He said the door to the family’s duplex in West Stewartstown had been left unlocked the night before and someone else was in the apartment after he and Celina’s mother, Luisia Cass, had gone to bed.

“I had nothing to do with it,” Noyes said. “We left the door unlocked, and somebody else was in the apartment after we went upstairs.”

An autopsy failed to pinpoint how Celina died. Toxicology tests are pending.

Noyes initially spoke to reporters about Celina’s disappearance but later stopped speaking out. He is now living alone. He confirmed to WMUR that Celina’s mother, whom he married a year ago, doesn’t want him around.
