Manhunt Ends with Suspect Dead in Brown, MIT Shootings; Motive Still Unknown

A five-day, multi-state manhunt for the gunman who killed two Brown University students and an MIT professor ended Thursday night when authorities found the suspect, 48-year-old Claudio Manuel Neves Valente, dead of an apparent self-inflicted gunshot wound inside a New Hampshire storage unit nytimes +1. Officials said the discovery appeared to close the urgent search but left critical questions unanswered, including any clear motive for the two linked attacks nytimes +1.

Investigators said Valente, a Portuguese national and former Brown physics graduate student, was believed to have opened fire in a crowded Brown University lecture hall on December 13, killing students Ella Cook, 19, and MukhammadAziz Umurzokov, 18, and wounding nine others, before fatally shooting MIT professor Nuno F.G. Loureiro, 47, outside his Brookline, Massachusetts home two days later nytimes +2.

How Investigators Tracked the Suspect Across Three States

Authorities said the break in the case came from a combination of license-plate readers, rental-car and storage records, surveillance footage and public tips that helped them identify a gray Nissan Sentra tied to both crime scenes nbcboston +1. A Reddit user who flagged similarities between a vehicle in police images and a rental-car listing “blew this case right open,” Rhode Island Attorney General Peter F. Neronha said, underscoring the role of online sleuthing in the investigation theguardian.

Court affidavits described a trail that began when Valente rented the Sentra in Boston on December 1 and was repeatedly picked up by plate readers in Providence in the days before the Brown shooting nbcboston +1. After Loureiro was shot on December 15, investigators traced the same car north to a Salem, New Hampshire storage facility, where records showed Valente had rented a unit in November and appeared to have swapped license plates and used multiple phones to conceal his movements nbcboston +1.

Unanswered Questions About Motive and Political Fallout

Officials across Rhode Island and Massachusetts said investigators had yet to determine why Brown University or Loureiro were targeted, despite the suspect’s past ties to both institutions’ physics communities nytimes +2. “In terms of why Brown? I think that’s a mystery,” Neronha said, adding that authorities were still examining any personal or professional links between Valente and the MIT professor, who had studied at the same Lisbon institute decades earlier cbsnews +1.

The case quickly rippled into national politics after Homeland Security Secretary Kristi Noem announced a pause to the Diversity Immigrant Visa program, saying Valente had become a U.S. permanent resident in 2017 through the lottery nytimes +1. Immigration-law specialists noted that the long-established program, which issues about 50,000 visas annually to applicants from underrepresented countries, was created by Congress and predicted legal challenges to any unilateral suspension pbs. Community leaders, meanwhile, called for reviews of campus security at Brown, where the shooter was able to enter the physics building and unleash more than 40 rounds before fleeing foxnews +1.

The Bigger Picture

With the suspect dead and the immediate threat over, investigators are now focused on reconstructing Valente’s path to violence, from his brief stint as a Brown graduate student in the early 2000s to his actions in the days before the shootings nytimes +1. Law enforcement officials emphasized that the case remains open as they probe his digital history, weapons purchases and possible grievances, even as the families of three victims and two elite academic communities seek answers to why they were targeted nbcboston +1.
