With his Rwandan-born wife Dafroza, Alain Gauthier has devoted decades of his life to tracking down genocide suspects who have found refuge in France. So far, the Gauthiers' efforts have led to about 30 legal cases being initiated in France against Rwandan suspects, all of them men. Alain Gauthier used a recent trip to Rwanda to seek testimony against Claude Muhayimana, a former hotel driver in Rwanda who took refuge in France and gained French nationality in 2010. He is accused of having transported militiamen to sites in the west, including the Bisesero region, where massacres were carried out. His trial was due to begin in Paris on February 2 2021, but has been delayed owing to the coronavirus pandemic making it difficult for witnesses to travel.
