The Trump administration has suspended the green-card-lottery program, which allowed the suspect in the Brown and MIT killings to come to the US.
Claudio Neves Valente, a Portuguese national, entered the US on a student visa in 2020 and became a permanent resident in 2017.
Valente was found dead on Thursday in an apparent suicide.
In an announcement on X, Homeland Security Secretary Kristi Noem described Valente as a “heinous individual.”
“The Brown University shooter, Claudio Manuel Neves Valente entered the United States through the diversity lottery immigrant visa program (DV1) in 2017 and was granted a green card,” she wrote.
“This heinous individual should never have been allowed in our country.
“In 2017, President Trump fought to end this program, following the devastating NYC truck ramming by an ISIS terrorist, who entered under the DV1 program, and murdered eight people.
“At President Trump’s direction, I am immediately directing USCIS to pause the DV1 program to ensure no more Americans are harmed by this disastrous program.”
The DV1 visa program makes around 50,000 green cards available each year by lottery to people from countries that have less representation among the US population, especially in Africa.
According to The Guardian, “Nearly 20 million people applied for the 2025 visa lottery, with more than 131,000 selected when including spouses with the winners. After winning, they must undergo vetting to win admission to the US. Portuguese citizens won only 38 slots.
“Lottery winners are invited to apply for a green card. They are interviewed at consulates and subject to the same requirements and vetting as other green-card applicants.”
An autopsy revealed Valente died of a self-inflicted gunshot wound to the head on Tuesday, two days before police found his body.
Inside the storage unit where his body was discovered, police also found a satchel with two guns.
Valente, a PhD student at Brown more than 20 years ago, was identified as the culprit of the mass shooting there last weekend that killed two and injured nine more.
Students Ella Cook, a 19-year-old sophomore from Alabama, and Mukhammad Aziz Umurzokov, an 18-year-old Uzbek American freshman, were killed in the shooting last Saturday.
Valente then travelled 50 miles and shot dead MIT professor Nuno Loureiro at his Brookline townhouse, two days later.
Valente and Loureiro had been classmates at the Instituto Superior Técnico in Portugal.
The killer’s motives are, at present, unclear, authorities say.
“I don’t think we have any idea why now, or why Brown, or why these students, why this classroom,” Rhode Island Attorney General Peter Neronha told reporters at a Thursday press conference.
It’s claimed Valente made strange “barking” noises as he fired during his rampage at Brown.
