Law enforcement officials found Claudio Neves Valente dead in a New Hampshire storage facility, ending a multi-state manhunt after the Brown University lecture-hall shooting that killed two students and the separate slaying of an MIT professor. Providence and federal investigators say Neves Valente, a former Brown graduate student, acted alone; authorities continue to seek motive and review his past affiliations. The discovery triggered immediate federal policy action: Homeland Security, at the president’s direction, ordered a pause in the Diversity Immigrant Visa (green card lottery) program. The suspension — announced by Secretary Kristi Noem — ties a campus safety investigation to immigration policy and is likely to spark legal and institutional pushback as universities and international-student offices weigh impacts on vetting, campus climate and enrollment pipelines.
