Mohamedou Slahi was born in a small town in Mauritania in 1970. He won a scholarship to attend college in Germany and worked there for several years as an engineer. He returned to Mauritania in 2000. The following year, at the behest of the United States, he was detained by Mauritanian authorities and rendered to a prison in Jordan; later he was rendered again, first to Bagram Air Force Base in Afghanistan, and finally, on August 5, 2002, to the U.S. prison at Guantánamo Bay, Cuba, where he was subjected to severe torture. In 2010, a federal judge ordered him immediately released, but the government appealed that decision. The U.S. government has never charged him with a crime. He remains imprisoned in Guantánamo.
