Authorities announced the end of a multistate manhunt after Claudio Neves Valente, a 48‑year‑old former Brown student, was found dead of a self‑inflicted gunshot wound in a New Hampshire storage unit. Investigators now say he is the suspected gunman in the Brown University lecture‑hall shooting that killed two students and injured nine, and in the slaying of an MIT professor two days later. Police tied the Brown and MIT attacks to the same individual through video, vehicle sightings and tipster information. Valente had been enrolled at Brown in 2000–01; investigators noted prior connections between him and the MIT victim dating back to academic programs in Portugal. The case prompted immediate administrative and political reactions — including a White House suspension of the diversity visa lottery program — and renewed scrutiny of campus safety, vetting and post‑incident support for students and staff at research universities.
