President Donald Trump on Friday ordered a suspension of the US Diversity Visa (DV) “green card” lottery after a mass shooting at Brown University on 13 December left two students dead and nine injured. Officials say the suspect, 48-year-old Claudio Neves Valente, entered the United States through the diversity immigrant visa programme (DV1) in 2017 and was later found dead on Thursday in Salem, New Hampshire. Homeland Security Secretary Kristi Noem said she has paused the programme to “ensure no more Americans are harmed by this disastrous programme.” Federal and local investigators have linked the Brown attack to an earlier killing this week of MIT professor Nuno F. Gomes Loureiro in Brookline, Massachusetts.
Key Takeaways
- The Brown University shooting occurred on 13 December; two students died (Ella Cook, 19, and Mukhammad Aziz Umurzokov, 18) and nine others were wounded during final exams.
- The suspect, Claudio Neves Valente, 48, reportedly entered the US under the DV1 lottery in 2017 and was granted a green card.
- Valente was found dead in Salem, New Hampshire, with a satchel and two firearms; investigators believe the death was from a self-inflicted gunshot wound.
- Officials say evidence linked the same vehicle to the Brookline killing of MIT professor Nuno F. Gomes Loureiro, 47, on Monday, roughly 50 miles from Providence.
- The Diversity Visa programme makes up to 50,000 visas available annually through random selection from eligible low-immigration countries.
- Homeland Security Secretary Kristi Noem said the pause was taken at President Trump’s direction; Noem cited past concerns after the 2017 New York truck attack.
- Investigators used CCTV, public tips and car-rental records during a six-day multi-state manhunt that led to the suspect’s identification.
Background
The Diversity Visa (DV) lottery program, often called the green card lottery, began to broaden immigrant admission from countries with historically low US immigration rates; the programme awards up to 50,000 immigrant visas each year through random selection. Supporters view it as a tool for family and national diversity and argue it helps applicants who lack other legal pathways; critics have long pushed for stronger vetting or elimination, citing security concerns tied to rare but high-profile criminal acts by lottery entrants.
In 2017, the truck-ramming attack in New York that killed eight people was carried out by Sayfullo Saipov, an Uzbek national who entered through the DV1 scheme; that incident prompted political calls for reform or termination of the lottery. Over time, administrations and Congress have debated how to balance humanitarian, economic and security priorities when setting immigration rules. Key stakeholders include the Department of Homeland Security, immigrant advocacy groups, law enforcement agencies and institutions that host international students and scholars.
Main Event
On 13 December, a gunman entered Brown University’s engineering building during final exams and opened fire, killing two students and wounding nine others. The two students have been identified as Ella Cook, 19, from Alabama, and Mukhammad Aziz Umurzokov, 18, an Uzbek-American freshman. Campus and city police launched an immediate manhunt after the attack; authorities later identified a vehicle of interest via CCTV and public tips.
Investigators traced the vehicle to a car-rental location and matched the renter’s name to the person of interest; the suspect was located six days later and discovered dead in a storage facility in Salem, New Hampshire. Rhode Island Attorney General Peter Neronha said evidence recovered in a nearby car matched items and ballistics from the Brown shooting scene. The suspect was found with a satchel and two firearms, according to law enforcement statements.
Separately, officials say the same vehicle was seen near the Brookline residence of MIT professor Nuno F. Gomes Loureiro, 47, who was shot and killed on the Monday before the Brown attack. Police reported that both men — the Brown victims and the MIT professor — had overlapping academic histories in Portugal in the late 1990s, and investigators are treating the two incidents as linked. Brown University President Christina Paxson confirmed the suspect had been enrolled at Brown from autumn 2000 to spring 2001 while pursuing PhD-level work but said he had “no current active affiliation” with the university.
Analysis & Implications
The immediate policy response — a suspension of the DV lottery — thrusts visa screening and immigration policy back into the political spotlight. Administrations that move to halt or restrict the lottery typically cite public-safety risks, while immigrant-rights advocates argue such actions stigmatize lawful entrants and punish many applicants for the actions of a few. Any sustained suspension will trigger legal, administrative and diplomatic workstreams to define criteria for reinstatement or legislative reform.
A suspension may prompt expedited review of vetting protocols used for DV winners, including criminal-record checks, biometric screening and interagency intelligence-sharing procedures. Security officials will likely be pressured to demonstrate how a random-selection program established on statutory criteria could fail to intercept an individual who later commits violent crime. At the same time, the operational burden on consular posts and domestic agencies could grow if additional layers of screening are mandated.
Politically, the move can be expected to deepen partisan debate: proponents of tighter immigration controls will point to the Brown and 2017 New York cases as justification, while opponents will emphasize the rarity of such incidents relative to the programme’s annual scale. Internationally, Portugal may seek clarifications on the suspect’s travel and immigration record; diplomatic communications are customary when a foreign national is implicated in crimes abroad. For higher education and research institutions, renewed scrutiny may lead to changes in campus safety protocols, visitor vetting and support for international students.
Comparison & Data
| Item | Figure/Year |
|---|---|
| Annual DV visas available | Up to 50,000 |
| Notable prior attacker via DV1 | Sayfullo Saipov, 2017 (8 killed in NYC attack) |
| Brown University shooting (this report) | 13 Dec — 2 killed, 9 injured |
The table provides basic context: the DV programme issues up to 50,000 immigrant visas annually, and while most entrants live and work without incident, rare violent crimes by recipients have spurred policy debate. Comparing the 2017 NYC truck attack and the Brown incident illustrates why policymakers and the public often treat the lottery as a national-security question despite its low absolute incidence of related crime.
Reactions & Quotes
“I have paused the Diversity Visa programme to ensure no more Americans are harmed by this disastrous programme.”
Kristi Noem, Secretary of Homeland Security
Noem framed the pause as a safety measure and referenced prior concerns after the 2017 New York attack. Her statement followed the suspect’s identification and death, and was issued as investigators continued to piece together the suspect’s movements and motive.
“He had no current active affiliation to Brown.”
Christina Paxson, Brown University President
Paxson clarified the suspect’s historical student record and emphasized Brown’s immediate response to student safety and support services for victims and their families. The university has activated counseling and liaison services for students and staff affected by the incident.
“Evidence recovered matched the scene of the Providence shooting.”
Peter Neronha, Rhode Island Attorney General
Attorney General Neronha described forensic links between items found near the suspect and the Brown shooting scene, and confirmed investigators were treating the Brookline and Providence incidents as connected while motive remained under investigation.
Unconfirmed
- Motivation for the shootings: authorities have not released a confirmed motive connecting the suspect to either incident.
- Any ideological or organizational links: no verified ties to extremist groups have been publicly confirmed in connection with these attacks.
- Systemic vetting failures: investigators have not released definitive findings that the DV process itself failed in a specific, reproducible way.
Bottom Line
The suspension of the Diversity Visa lottery is an immediate policy response to a pair of linked killings that federal officials say involved a 2017 DV entrant. The action is likely to produce intense debate over immigration vetting, with calls for quicker intelligence-sharing and enhanced screening counterbalanced by civil-rights concerns and legal challenges to broad programmatic shutdowns.
For observers, the next steps to watch are (1) the outcome of criminal and forensic investigations that may clarify motive and potential accomplices, (2) any formal reviews or rule changes issued by the Department of Homeland Security and State Department, and (3) legislative reactions in Congress that could seek to alter or replace the DV programme. Universities and law enforcement nationwide will also be scrutinizing campus safety protocols and emergency communications in the weeks ahead.
