Munyaneza was the first person to be arrested under that law, which was passed to give formal recognition to Canada's obligations to the International Criminal Court.
Munyaneza is alleged to have committed the acts near Butare, Rwanda, in 1994.
In March 2007, Munyaneza's trial began with the testimony of a woman, identified only as witness C-15, who stated that she had pretended to be dead for three days and smeared her sister's blood on her body in order to hide from Interahamwe gangs.
On April 10, a witness known as C-17 testifed that Munyaneza had raped her four times, and that she had witnessed him personally raping and killing others.
On April 11, Munyaneza was severely beaten in his cell at the Rivières-des-Prairies prison by a 17-year old who had heard about the details of Munyaneza's trial in the media.
