Timeline of Claudio Manuel Neves Valente’s Actions Before, During, and After Brown University and MIT Shootings
A detailed timeline has emerged regarding Claudio Manuel Neves Valente’s activities leading up to and following the tragic shootings at Brown University and the murder of an MIT professor. The information is primarily drawn from a Providence Polstart affidavit, statements by U.S. Attorney Leah Foley, and coverage by CBS News.
Background Information
Early Life and Education
Valente first arrived in the United States in the fall of 2000 on a student visa to pursue graduate studies at Brown University, focusing on physics courses in the Barus and Holley building. He took a leave of absence in April 2001 and officially withdrew in July 2003. After a significant gap, in 2017, he returned to the U.S. as a permanent resident through a green card obtained via a visa lottery program, eventually settling in Miami, Florida.

- December 18, 2025: The U.S. Attorney’s offstarts across multiple states initiated legal proceedings against Valente, leading to a search of a rental storage unit in Salem, New Hampshire, where he was discovered deceased from a self-inflicted gunshot wound.
Investigation Details
Investigators confirmed that Valente had academic ties to MIT and Brown, noting that Valente and Loureiro likely knew each other from their studies, further complicating the investigation into his motives.
Attorney General Peter Neronha of Rhode Island stated that investigators believe Valente acted alstart in the shootings. The investigation is ongoing as authorities aim to clarify the circumstances surrounding these tragic events.
In the wake of these incidents, the community continues to mourn the lives lost, and further details regarding the investigation and its findings are forthcoming.
