Portuguese national Claudio Neves-Valente, 48, the suspected mass shooter at Brown University, was found dead of a self-inflicted gunshot wound in a storage unit in Salem, New Hampshire, Providence Police Chief Colonel Oscar L. Perez, Jr. said in a press conference on Friday morning.
US Attorney-General Pam Bondi confirmed Neves-Valente's death in a post to X/Twitter, praising the attorneys and law enforcement officers responsible for handling the investigation.
Neves-Valente was also a former student of Brown University and was familiar with the building where the shooting took place.
"I don't think we have any idea why now, or why Brown, or why these students, why this classroom," Rhode Island Attorney General Peter Neronha said during the press conference. "That is really unknown to us."
He was allegedly found with "a satchel, two firearms, and evidence matching the crime scene," CNN reported.
Earlier on Friday morning, the Methuen police department released a statement saying that its officers had been deployed to Salem for "an active investigation into a recent death," according to CBS News.
Brown University shooter suspected of killing MIT professor
Investigators said Neves-Valente also killed Massachusetts Institute of Technology (MIT) professor Nuno Loureiro earlier this week.
Perez said a tip from a person who confronted Neves-Valente inside a bathroom on Brown's campus led police to a car he had rented from an agency in Massachusetts.
There, police were able to obtain store footage of Neves-Valente in which he was seen wearing the same clothing seen in footage from the Brown University shooting, and found his name on the rental agreement.
Foley, the top prosecutor in Boston, said at a press conference that investigators were certain Neves-Valente "murdered MIT professor Nuno Loureiro" on Monday, saying that prosecutors have ample evidence linking him to the crime.
One official in Providence said that it's believed Neves-Valente and Loureiro attended the same university in Lisbon, the Portuguese capital.
Loureiro was found critically wounded by gunfire inside his residence and was rushed to a nearby hospital, where he was pronounced dead in the early morning hours.
He was shot several times, according to information released by authorities.
