The investigation into Nusrat's death revealed a conspiracy to silence her which included her own classmates and a number of powerful men from within the community.
Three teachers, including the headmaster, Siraj Ud Doula, who police say ordered the killing from prison after he was arrested under suspicion of harassment, were found guilty by the court on Thursday. Another two of the defendants found guilty, Ruhul Amin and Maksud Alam, are local leaders of the ruling Awami League party.
A number of local police were found to have collaborated with those convicted in spreading false information that Nusrat had committed suicide. The officers were not among those tried for Nusrat's murder.
