Authorities have identified the suspect in the December 13, 2025, shooting at Brown University as Claudio Manuel Neves-Valente, a 48-year-old Portuguese national from Miami, Florida, and a former Brown University PhD physics student.

The attack left two students dead and nine others injured, prompting a large-scale investigation involving campus police, state authorities, the FBI, and multiple federal agencies. Law enforcement officials say the suspect fled the scene following the shooting, triggering a multi-state manhunt.

Investigators later linked Neves-Valente to a separate homicide involving an MIT professor, intensifying the urgency of the search. Authorities tracked a rental vehicle associated with the suspect after discovering its license plates had been switched, a development that helped narrow his movements across state lines.

The investigation was further accelerated by a tip originating from Reddit, which directed authorities toward the suspect’s whereabouts. On December 19, law enforcement confirmed that Neves-Valente died by suicide in Salem, Massachusetts, bringing the active search to an end.

Officials emphasized that while the suspect is deceased, the investigation remains ongoing as authorities work to establish a complete timeline, examine motives, and assess any missed warning signs. University and state leaders continue to face scrutiny over campus security measures and response protocols in the wake of the tragedy.

As the Brown University community mourns the victims, calls for accountability, transparency, and improved campus safety have intensified, with many demanding answers about how the suspect was able to carry out the attack and evade capture for several days.
