Prosecutors Link Brown University Shooting and MIT Professor’s Killing to Single Suspect Found Dead

Overview

• Federal and local officials said they are certain Portuguese citizen Claudio Neves Valente, 48, carried out both the Brown attack and the killing of MIT physicist Nuno Loureiro.
• Valente was found dead by suicide in a Salem, New Hampshire storage facility he had rented, where two firearms were recovered, including a 9mm believed to have been used.
• On December 13, the shooter fired at least 44 rounds in Brown’s engineering building during final exams, killing two students and wounding nine.
• On December 15, Loureiro, 47, was shot at his Brookline residence and later died at a Boston hospital, according to authorities.
• Police traced a gray Nissan with Florida plates from a Reddit witness tip to rental records and surveillance, identified Valente, and say the motive remains unknown; the men appear to have studied at the same Lisbon university, and reports of a possible Iranian link are under preliminary review with no proof.
