A federal jury in Boston convicted Eric Nshimiye, a 55-year-old Rwandan-born US citizen, on four counts of perjury and one count of obstruction of justice. The charges stem not from the genocide itself — US courts lack jurisdiction over crimes committed in Rwanda — but from Nshimiye's lies about his involvement: first to immigration officials when obtaining citizenship in 2009, then under oath in a 2019 federal trial of his former medical school roommate Jean Leonard Teganya, who was separately convicted of genocide participation. The trial turned on competing witness testimony about Nshimiye's whereabouts during the 100-day massacre that killed more than 800,000 Tutsis in 1994. Prosecution witnesses from Rwanda placed Nshimiye in Butare, participating in killings and affiliated with the Interahamwe paramilitary group and the pro-Hutu National Revolutionary Movement for Development. Defense witnesses placed him in Kigali. The jury sided with the prosecution. Nshimiye's defense raised a structurally important point: he was never implicated by the International Criminal Tribunal for Rwanda, nor by Rwanda's gacaca transitional justice courts, which tried over a million people. Defense attorneys also alleged Rwandan authorities had met with prosecution witnesses before they testified in Boston, suggesting coordination that could taint testimony. These arguments did not prevail, but they illuminate the evidentiary fragility inherent in prosecuting 30-year-old atrocity cases across continents. The prosecution's framing was blunt. Assistant Attorney General A. Tysen Duva stated Nshimiye had "concealed his involvement in the 1994 Rwandan genocide and the heinous acts of violence he committed, including clubbing people to death" for nearly three decades. The DOJ's Criminal Division treated the case as both a fraud-on-the-immigration-system case and a broader accountability signal. Nshimiye's attorneys have already filed a motion arguing he should be released, noting his two and a half years of pre-trial detention exceeds typical sentences for these charges. His son Tresor told Al Jazeera the family expected acquittal and found the verdict "quite shocking." The emotional weight is real — Nshimiye's US-born children were present for the conviction. This case is not isolated. In April 2025, prosecutors charged Faustin Nsabumukunzi, a 65-year-old Long Island beekeeper, with concealing genocide participation on citizenship paperwork. In June 2025, Vincent Nzigiyimfura of Dayton, Ohio, was charged identically. Both were previously listed as fugitives by Rwandan authorities. A pattern is emerging: US Homeland Security investigations, cross-referencing with Rwandan fugitive lists, are systematically identifying naturalized citizens who lied about genocide involvement. The institutional question is whether US federal courts, prosecuting perjury and immigration fraud rather than the underlying atrocities, can deliver meaningful accountability three decades after the fact — or whether the distance in time, geography, and legal framing creates a justice system operating at the margins of what evidence can reliably support.
