UPDATE ON INVESTIGATION INTO BROWN UNIVERSITY AND BROOKLINE SHOOTINGS

Statement released by U.S. Attorney’s Office for the District of Massachusetts BOSTON – The Department of Justice, alongside our law enforcement partners, has been actively investigating the facts and circumstances surrounding the mass shooting at Brown University and the homicide of an MIT professor in Brookline, Mass. The investigation into these horrific acts remains ongoing. As part of the investigation on Dec. 18, 2025, investigators executed a federal search warrant at a storage facility used by Claudio Manuel Neves Valente, the Portuguese national responsible for the senseless murders. During the search of the storage facility, the FBI recovered an electronic device containing a series of short videos made by Neves Valente after the shootings. Today, the Department of Justice is releasing the transcripts of these videos, which have been translated from Portuguese to English. In these videos, Neves Valente admitted that he had been planning the Brown University shooting for a long time. Although Neves Valente stated that Brown University was his intended target, based on initial review of the evidence collected, he did not provide a motive for targeting students at Brown University or the professor at MIT. Neves Valente showed no remorse during the recordings; on the contrary, he exposed his true nature when he blamed innocent, unarmed children for their deaths at his hand and grumbled about a self-inflicted injury he suffered when he shot the MIT professor at close range. Our investigation into the motives behind Neves Valente’s heinous acts will continue. Based on the evidence seized and analyzed to date, authorities do not believe there are any ongoing public safety threats associated with the shootings. Additional updates will be provided as further information is developed and following appropriate victim notification.
