SANFORD, Fla. -

A judge on Monday said that he will allow the confession of a Casselberry woman accused of strangling her 2-year-old daughter with a bra.

Her attorney, Tim Caudill, asked Circuit Judge Jessica Recksiedler to disallow the confession made by 24-year-old Nioshka Bello.  

"Testimony is quite clear that at some point in time she even becomes catatonic because of the events that occur," Caudill said.

Caudill said she couldn't have known she had the right to remain silent when she confessed while locked in a mental hospital.

"None of the statements that were made were voluntary," Caudill said.

She is accused in the September 2009 death of Janessa Sandoval.

Casselberry police say Bello tried to kill herself with pills before strangling Janessa after getting into a fight with the girl's father.

Prosecutors said she was "alert, intelligent and gave a knowing and voluntary waives of her rights."

Bello has twice been sent to mental hospitals.

Last week, the judge ruled her competent to stand trial.
