Additional District Judge Nitynanad Singh in Koderma town rejected the appeal for bail, her lawyer Arun Mishra told IANS over telephone, adding he would move the high court.
"She has been implicated in her daughter's death," Mishra said.
Sudha was arrested May 3 on charges of killing Nirupama. The family insists that Nirupama, who was pregnant at the time, committed suicide.But her boyfriend Priyabhanshu Ranjan alleged that she was killed by her family members who were against their relationship.
The anomalies in the autopsy report of Nirupama have confused the investigators.
According to police, the team that did the autopsy did not mention the time of her death. Her viscera and foetus she carried were not preserved. Also, the report did not mention the injury marks on Nirupama's body.
