Four men were convicted Tuesday in the fatal gang rape last year of a 23-year-old student in Delhi, a case that shocked the nation and led to countrywide protests and, eventually, stricter laws against sexual assault. Mukesh Singh, Vinay Sharma, Akshay Thakur, and Pawan Gupta all face the death penalty, although they have maintained their innocence, and lawyers for three of the men said they plan to appeal the conviction. Sentencing will begin Wednesday. Protesters outside the Delhi courtroom Tuesday called for the convicted to be hanged. They were accused of raping a 23-year-old student on a bus in December. She died 10 days later from massive internal injuries—but not before she testified against her attackers.
