Police have confirmed that the suspected Brown University shooter, identified as 48-year-old Claudio Neves-Valente, died by suicide this evening in a storage unit in Salem, New Hampshire.

Neves-Valente was a Portuguese national and not a U.S. citizen. He held a green card from Portugal and attended Brown University from 2000 to 2001 as a graduate physics student.

Authorities have determined that Neves-Valente is responsible for both the mass shooting at Brown University and the murder of an MIT professor who was also Portuguese. Police believe the suspect and the slain MIT professor attended the same university in Lisbon, Portugal.

Christina Paxson, president of Brown University, stated that Neves-Valente spent significant time in the building where the shootings occurred during his student years.

Federal officials confirmed there is no longer a public threat following the suspect’s death. Police have established that the two incidents were linked and Neves-Valente has been accounted for. The motive behind the attacks remains under investigation, with authorities reporting it has not yet been disclosed.
