LANCASTER, N.H. — A hearing is planned on whether a New Hampshire man accused of murdering his 11-year-old stepdaughter five years ago is mentally competent to stand trial.

The competency hearing for 52-year-old Wendell Noyes is scheduled for Nov. 21 in Lancaster. It was rescheduled from September.

Noyes is accused of murdering 11-year-old Celina Cass by submerging her body in the Connecticut River, where she was found six days after she was reported missing in July 2011. Her disappearance led to a search by federal, state and local law enforcement in the North Country town of Stewartstown, a mile from the Canadian border.

Noyes is charged with second-degree murder.

His public defender, Marcie Hornick, has said Noyes’ competency must be determined before a probable cause hearing can be scheduled.
