India’s Supreme Court on Wednesday rejected the final appeal of one of the four men sentenced to death for the 2012 gang rape and murder of a woman on a bus in New Delhi, paving the way for the four to be hanged.

The case made international headlines and helped expose the scope of sexual violence against women in India, prompting lawmakers to stiffen penalties in rape cases.

The victim, a 23-year-old physiotherapy student whom Indian media called “Nirbhaya,” or “Fearless,” because Indian law prohibits rape victims from being identified, was heading home with a male friend from a movie theater when six men lured the couple onto a bus.

They beat the man with a metal bar, raped the woman and used the bar to inflict extensive internal injuries to her. The pair were dumped naked on the roadside, and the woman died two weeks later.
