Claudio Neves Valente was a 48-year-old Portuguese national identified as the gunman in the tragic 2025 Brown University shooting and related MIT attack. He fatally shot two Brown students and targeted an MIT professor before being killed in a confrontation with police. Details emerged from investigations and public records shortly after the December 2025 incident.

Background

Born in Portugal, Valente studied physics at Instituto Superior Técnico, Portugal's top engineering school, from around 1995 to 2000. Classmates described him as brilliant yet arrogant, and he was let go from a position at the Lisbon university in early 2000. He later pursued a physics PhD at Brown University in Providence, Rhode Island, living there during his enrollment but withdrawing in July 2003 after a leave of absence.

Time at Brown

At Brown, Valente complained about classes being too easy and campus food quality, according to a former classmate and friend, Scott Watson, a Syracuse University physics professor. No evidence confirms him as an alumnus or recent student; he had left over two decades earlier. Forum discussions on Reddit's r/BrownU speculated on his motives, noting his travel from Miami to target specific locations like a classroom and professor's home.

Pre-Shooting Life

Little is publicly known about his post-Brown years, but reports indicate he visited a New Hampshire shooting range beforehand. Former Portuguese colleagues called him talented amid probes into his rampage's triggers. An archived Brown student directory message surfaced, adding to the emerging profile.

Incident Details

On December 2025, Valente carried out targeted shootings at Brown, killing two students, then went to an MIT professor's home—someone who attended the same Portuguese program as him. Police sources confirmed his actions as deliberate.

TL;DR: Claudio Neves Valente, ex-Brown PhD student from Portugal, perpetrated the 2025 Brown/MIT shootings, killing two before dying in police action; described as smart but troubled.
