Timeline and what investigators say
Dec. 13, ~4 p.m. — Investigators say a man entered a classroom in the Barus and Holley engineering building and fired more than 40 rounds from a 9mm handgun. Two students were killed and nine were wounded before the attacker fled on foot, according to law enforcement briefings and news reports. (Sources: Fox News live coverage, CBS News)
Dec. 15–16 — Two days later, authorities say the same suspect shot MIT professor Nuno F.G. Loureiro multiple times at Loureiro’s Brookline residence. Loureiro, 47, a well‑regarded nuclear fusion scientist and director of MIT’s Plasma Science and Fusion Center, died the following day. Investigators have said they believe the Brown shooting and the killing of Loureiro are connected. (Sources: ABC News, Fox News live coverage)
How investigators identified Neves‑Valente
Officials traced the suspect through a mix of surveillance footage, rental records, hotel stays and financial leads. Investigators say a gray Nissan Sentra rented in Boston on Dec. 1, with Florida plates, helped track movements tied to both incidents. Video footage near Brown University, surveillance around Loureiro’s apartment, and a Providence car dealership also factored into identifying the suspect.
A witness who reviewed video came forward to assist investigators, according to reporting. After the Brookline shooting, authorities say the car was left in the area and the suspect later entered a storage facility in Salem, New Hampshire. Federal agents breached a storage locker there around 9 p.m. on Dec. 18 and found Neves‑Valente dead from an apparently self‑inflicted gunshot wound. Law enforcement recovered a satchel and two firearms from the unit. Rhode Island Attorney General Peter Neronha and U.S. Attorney Leah B. Foley confirmed the identity and said the active manhunt had ended. (Sources: CBS News, Fox News live coverage)
Background on the suspect
Personal and educational history: Claudio Manuel Neves‑Valente was born in Portugal and studied physics at Brown University from the fall of 2000 to the spring of 2001, according to Brown President Christina Paxson. He took a leave of absence and ultimately withdrew in 2003.
U.S. status and residency: Investigators report his last known U.S. address was in Miami, Florida. He entered the United States in 2017 through the diversity visa lottery (DV1) and was granted a green card, according to reporting. (Source: CBS News)
Authorities say Neves‑Valente and Loureiro both attended university in Lisbon from 1995 to 2000 and likely knew each other. Investigators have not publicly established a clear motive. A law enforcement source told reporters some who knew the suspect described him as a potential loner and suggested he had concerns about media coverage, but officials cautioned against drawing firm conclusions while the probe continues.

Federal charges and legal matters
While the investigation was ongoing, federal authorities said Neves‑Valente faced scrutiny for transporting a firearm and ammunition across state lines with intent to commit a felony. With his death, prosecutors said the criminal case would not proceed against him, and officials declared the active manhunt closed. U.S. and local law enforcement agencies remain involved to finalize investigative steps and notify next of kin. (Sources: Fox News live coverage, CBS News)
Reaction from officials and institutions
Brown University leaders responded with grief and calls for community support. Brown President Christina Paxson confirmed the student connection and urged calm as police conducted their work.
MIT released statements mourning the loss of Nuno Loureiro and praising his scientific contributions. Local and federal officials held coordinated briefings as the manhunt unfolded.
“We ask for patience as investigators complete their work,” said officials in coordinated briefings, urging the public to avoid speculation.
Political response: Homeland Security Secretary Kristi Noem criticized Neves‑Valente’s entry into the United States via the visa lottery program, arguing for tighter controls. Other public figures and campus safety advocates urged restraint until investigators released full findings. (Source: Fox News live coverage)
How the manhunt unfolded
After the Brown shooting, investigators traced intermittent sightings of the suspect’s vehicle and movements. The timeline shows travel from Providence‑area locations to Brookline, then to the Salem storage facility. Officials said surveillance images captured the suspect entering the storage complex wearing the same clothes seen near the other crime scenes. Law enforcement also examined hotel, rental car and financial records to establish movement and timing. (Sources: Fox News live coverage, CBS News)
Implications for the United States
Economic impact: High‑profile campus shootings can raise costs for universities and local governments. Institutions often increase spending on security, counseling, and physical upgrades, potentially affecting fees and budgets.
Political consequences: The shootings are likely to intensify debate over public safety, campus security, mental health services and immigration policy. Some elected officials may cite the suspect’s diversity visa entry to push for changes; others will focus on gun safety and background checks.
Social effects: Students, faculty and surrounding communities face trauma, grief and anxiety. Counseling and long‑term mental health support will be needed. The loss of two students and a respected scientist reverberates across academic and research communities.
Cultural relevance & practical applications: Public conversation may focus on campus openness versus security, emergency alert systems, building access control, and how to keep learning spaces safe without fundamentally changing them. Universities will likely review protocols and consider investments in security and counseling.
What investigators say remains unfinished
Authorities have declared the manhunt over with Neves‑Valente’s death, but investigators continue to piece together motive, planning and whether any others were involved. Officials have not released a final report and caution the public against speculation until the investigation concludes.
Law enforcement agencies will continue to gather evidence from crime scenes, surveillance, records and witness interviews to complete their findings. Investigative work is ongoing and officials stress that conclusions should await the full report. (Sources: CBS News, Fox News live coverage)
