Background on Neves-Valente
Investigators say Neves-Valente was a Portuguese national who studied physics at Brown from fall 2000 to spring 2001. Brown President Christina Paxson told reporters he had taken a leave of absence and ultimately withdrew in 2003 and had no current affiliation with the university. (Source: CBS News (AMP); Fox News)
Records show a man with the same name worked briefly at Instituto Superior Técnico in Portugal and was terminated from a monitoring position in 2000. That school is connected to aspects of Nuno Loureiro’s history. Investigators said Neves-Valente moved to the U.S. in 2017 and last lived in Miami; he reportedly came to the U.S. on a green card through the visa lottery. (Sources: Fox News; CBS News)
The shootings and timeline
Dec. 13, 2025 — Brown University: Authorities say a masked shooter entered Barus and Holley Room 166 around 4 p.m. during a finals review for ECON 0110, “Principles of Economics.” Video shows a stocky, masked figure about 5’8″ with an unusual gait. The attack left two students dead — one identified as Ella Cook — and nine wounded; six were hospitalized and reported stable as of Dec. 18. (Sources: CBS News; Fox News)
Dec. 15, 2025 — Brookline: Two days later, MIT professor Nuno Loureiro was shot and killed at his Brookline home. Brookline is roughly 50 miles from Providence. Surveillance footage and vehicle tracking link a rented vehicle seen in the Boston area to both locations. (Sources: Fox News; CBS News (AMP))
How investigators connected the cases
Federal and local authorities said the evidence tying Neves-Valente to both incidents included surveillance video, vehicle and hotel records, and bank or financial links. Surveillance reportedly showed a person resembling Neves-Valente near the Brown building in the days leading up to the shooting and near Loureiro’s apartment on the day of that killing. A car was seen around Brown from Dec. 1 to Dec. 12 and parked outside the building on the day of the shooting.
Authorities briefly pursued a person of interest seen at a hotel but later ruled that person out. The multi-agency investigation included the FBI, U.S. attorney’s office, state law enforcement and local police in Providence and Brookline. U.S. Attorney Leah B. Foley and Rhode Island Attorney General Peter F. Neronha confirmed investigators were confident in the identification; AG Neronha said his team was “100% confident this is our target.” (Sources: CBS News; Fox News)
Discovery in New Hampshire
On the evening of Dec. 18, federal agents breached a storage locker in Salem, New Hampshire, about 20 miles north of Boston. Inside they found Neves-Valente dead from an apparent self-inflicted gunshot wound. Officials said they recovered a satchel and two firearms. The U.S. attorney’s office and local prosecutors said the discovery closed the active pursuit of a suspect, though investigative work to determine motive and all facts will continue.

What officials and campus leaders have said
Brown University President Christina Paxson confirmed Neves-Valente had been a student two decades ago but stressed he had no current connection to the campus. Providence Mayor Brett Smiley noted that the timing — finals week and campus departures — complicated the city’s response and communications. Investigators emphasized that motive remained unclear as of the latest briefings. (Sources: CBS News (AMP); Fox News)
Investigative next steps
Authorities said their next steps include forensic testing, interviews, and a full review of digital, financial and travel records. Federal and local prosecutors will sort evidence from the Brown and Brookline scenes and work with Portuguese authorities if overseas records are needed. Officials warned that motive is often the hardest element to establish and that public statements will follow only when investigators are certain of facts. (Sources: CBS News; Fox News)
Implications for United States
The incidents raise several policy and community concerns:
- Public safety and campus security: The attacks renew debates over access controls, bag checks, and the value of uniformed security during high-traffic academic periods.
- Law enforcement coordination: The multi-jurisdictional response highlights the need for rapid information-sharing when suspects travel across state lines.
- Immigration and background screening: Investigators reported Neves-Valente arrived via the visa lottery in 2017; some will call for stronger background checks, while officials caution that immigration status alone does not explain violent acts.
- Mental health and resilience: The killings will renew calls for investment in campus mental health services and coordinated rapid-response plans that include surrounding communities.
- Travel and lodging vigilance: The suspect’s use of rented vehicles and hotels underscores the importance of lodging operators reporting suspicious repeat bookings.
“The investigative team is confident in its identification, but motive and full facts remain under review,” officials said.
