A deadly shooter who terrorized Brown University and murdered an MIT professor had been planning his calculated attacks for years, revealing a chilling level of premeditation that exposes dangerous gaps in our immigration screening processes.
Story Overview
- Claudio Neves Valente planned deadly attacks for at least six semesters before killing two Brown students and an MIT professor
- The 48-year-old Portuguese national entered the U.S. through the Diversity Visa program in 2017
- Valente left confession videos showing no remorse and died by suicide after a five-day manhunt
- President Trump ordered the suspension of the Diversity Visa program following the shooter’s death
Years of Calculated Planning Behind Deadly Campus Attacks
Claudio Neves Valente spent years meticulously planning his deadly rampage across two prestigious universities, according to confession videos recovered by federal authorities.
The 48-year-old Portuguese national admitted in recorded statements that he had been plotting the attacks for “at least six semesters,” passing up multiple opportunities due to hesitation. On December 13, 2025, Valente finally executed his plan at Brown University, killing two students and wounding nine others during final exams before fleeing the scene.
The shooter’s calculated approach extended beyond the Brown University attack. Two days later, on December 15, Valente murdered MIT professor Nuno F.G. Loureiro in his Brookline home.
Investigators discovered both men had attended school together in Portugal decades earlier, though Valente provided no explanation for specifically targeting his former classmate. This deliberate victim selection demonstrates the premeditated nature of these heinous crimes.
Diversity Visa Program Brings Killer to American Soil
Valente’s path to American citizenship raises serious concerns about immigration vetting processes that conservatives have long criticized. The shooter originally studied physics at Brown University on a student visa around 2000, departing in spring 2001.
He later gained permanent residency in September 2017 through the Diversity Immigrant Visa program, a lottery system that has faced scrutiny for its limited background screening requirements.
This case exemplifies the risks inherent in immigration programs that prioritize geographic diversity over thorough security assessments. Valente’s ability to obtain permanent residency despite his later confession of years-long violent planning highlights fundamental flaws in our immigration system.
The Diversity Visa program’s relatively minimal vetting process failed to identify the dangerous individual who would later terrorize American university campuses.

Shooter’s Disturbing Confession Videos Reveal Calculated Intent
Federal authorities recovered electronic devices containing Valente’s confession videos from the Salem, New Hampshire storage facility where he died by suicide on December 18. In these recordings, translated from Portuguese, the shooter expressed zero remorse for his actions, stating “I’m not going to apologize… no one apologized to me.”
He denied having mental illness or ideological motives, describing his crimes as “incompetent but something done” while maintaining his goal was ending his life on his own terms.

The confession videos debunked false rumors spread on social media, including baseless claims about Arabic phrases or terrorist connections. Valente’s own words confirm this was a personal vendetta rather than ideologically motivated terrorism.
His cold, calculated approach and complete lack of remorse underscore the premeditated nature of these attacks and the failure of immigration screening to identify such dangerous individuals before granting them permanent status in America.
