From CNN, writers Farid Ahmed and Moni Basu give us the graphic details.
Mahbub Khan came back to Shariatpur from a stint working in Malaysia. His son was Hena's age and the two were in seventh grade together.
Khan eyed Hena and began harassing her on her way to school and back, said Hena's father. He complained to the elders who run the village about his nephew, three times Hena's age.
The elders admonished Mahbub Khan and ordered him to pay $1,000 in fines to Hena's family. But Mahbub was Darbesh's older brother's son and Darbesh was asked to let the matter fade.
Many months later on a winter night, as Hena's sister Alya told it, Hena was walking from her room to an outdoor toilet when Mahbub Khan gagged her with cloth, forced her behind nearby shrubbery and beat and raped her.
Hena struggled to escape, Alya told CNN. Mahbub Khan's wife heard Hena's muffled screams and when she found Hena with her husband, she dragged the teenage girl back to her hut, beat her and trampled her on the floor.
The next day, the village elders met to discuss the case at Mahbub Khan's house, Alya said. The imam pronounced his fatwa. Khan and Hena were found guilty of an illicit relationship. Her punishment under sharia or Islamic law was 101 lashes; his 201.
Mahbub Khan managed to escape after the first few lashes.
Darbesh Khan and Aklima Begum had no choice but to mind the imam's order. They watched as the whip broke the skin of their youngest child and she fell unconscious to the ground.
"What happened to Hena is unfortunate and we all have to be ashamed that we couldn't save her life," said Sultana Kamal, who heads the rights organization Ain o Shalish Kendro.
Bangladesh is considered a democratic and moderate Muslim country, and national law forbids the practice of sharia. But activist and journalist Shoaib Choudhury, who documents such cases, said sharia is still very much in use in villages and towns aided by the lack of education and strong judicial systems.
