Federal authorities from the U.S. Department of Justice disclosed chilling details on January 7, 2026, confirming that Claudio Neves Valente, the 48-year-old Portuguese national and former Brown University graduate student who carried out deadly attacks in December 2025, had been methodically planning the violence for months and left behind a series of self-recorded confession videos recovered after his apparent suicide.

Neves Valente first struck on December 13, 2025, entering an engineering building on Brown's Providence campus where he fatally shot two current students and wounded nine others in a targeted rampage, before driving to the Boston suburb of Brookline two days later to murder MIT physics professor Nuno F.G. Loureiro—a former schoolmate from Portugal—at his home.

FBI agents searching the New Hampshire storage facility where Neves Valente's body was discovered on December 18 located an electronic device containing multiple brief videos filmed in the aftermath of the shootings, in which he calmly recounted in Portuguese his extensive preparations spanning at least six academic semesters without ever articulating a clear motive for selecting Brown or the specific professor.

Throughout the recordings, Neves Valente displayed a complete absence of remorse, defiantly declaring that he owed no apologies because none had been genuinely extended to him during his lifetime, while framing his actions as a deliberate choice to exit existence on his own terms rather than endure further personal suffering.

He further reflected on operational shortcomings, describing his execution as somewhat incompetent yet sufficient to achieve his ends, mentioning a self-inflicted eye injury sustained amid the chaos, acknowledging a tense pre-attack encounter with a perceptive witness who later identified his rental gray Nissan through Reddit posts that prompted crucial FBI tips, and expressing mild surprise at the duration authorities required to trace him despite his three-year rental of the eventual suicide site.
