The suspect in the fatal shootings at Brown University last weekend and of a Massachusetts Institute of Technology professor just days later was found dead of a self-inflicted gunshot wound Thursday night in Salem, New Hampshire, officials said.

The body of Claudio Neves Valente, 48 — a former Brown student and a Portuguese national — was found in a storage facility, WCVB-TV reported.

'We don’t know why now, why Brown, why these students, and why this classroom.'

Earlier Thursday multiple reports indicated a person of interest had been identified in the Brown shooting, which took the lives of two students and wounded nine others Saturday at the Ivy League school in Providence, Rhode Island. Authorities also were investigating possible ties between the Brown shooting and the fatal shooting Monday of MIT professor Nuno Loureiro at his home in Brookline, Massachusetts.

Providence police released several images and videos of a person of interest in the days following the deadly Brown shooting with no apparent luck.

But police told WCVB a witness provided investigators with a key tip: He saw someone who looked like the person of interest with a Nissan sedan displaying Florida plates.

That bit of information led Providence police to dive into a network of more than 70 street cameras operated around the city by surveillance company Flock Safety, the station said, adding that those cameras track license plates and other vehicle details.

Providence officials said the suspect then placed a Maine license plate over the rental car’s plate to help conceal his identity after he left Rhode Island for Massachusetts, WCVB reported.

The station said in a separate story that surveillance video from MIT professor Loureiro's Brookline neighborhood allegedly shows the gunman there days before the deadly shooting, according to Leah B. Foley, United States Attorney for the District of Massachusetts.

Investigators said video from inside Loureiro's apartment shows Neves Valente wearing a specific set of clothes before shooting the professor in the lobby Monday, WCVB reported.

A neighbor said in a WBZ-TV video report that the fatal shooting of Loureiro was a "surprise ... and a shooting in a state where it's so hard to even have a gun?" The neighbor also said fellow neighbors noted a nearby car was "parked in the wrong direction" and "seemed to be waiting."

Hours after the Loureiro shooting, Foley said surveillance video from a storage unit facility in Salem, New Hampshire, shows the gunman wearing the same clothes seen on the Brookline cameras, the station added. Neves Valente was found dead inside the storage facility Thursday night.

Brown University President Christina Paxson said Neves Valente was enrolled at the college from the fall of 2000 to the spring of 2001, the station said, adding that he was admitted to the graduate school to study physics beginning in September 2000. Paxson said he had "no current affiliation with the university,” WCVB reported.

Neves Valente had studied at Brown on a student visa and obtained legal permanent residence status in September 2017, the station said, adding that his last known residence was in Miami.

Rhode Island Attorney General Peter Neronha told WCVB there are “a lot of unknowns” in regard to motive: “We don’t know why now, why Brown, why these students, and why this classroom."

Foley said Neves Valente and Loureiro were former classmates at an academic program in Portugal between 1995 and 2000, the station noted.

Loureiro graduated in 2000 from the physics program at Instituto Superior Técnico, Portugal’s premier engineering school, WCVB reported, citing his MIT faculty page.

Neves Valente in 2000 was let go from a position at the Lisbon university, the station said, citing an archive of a termination notice from the school’s then-president in February 2000.

More from WCVB:

Loureiro, 47, who was married, joined MIT in 2016 and was named last year to lead the school’s Plasma Science and Fusion Center, where he worked to advance clean energy technology and other research. The center, one of MIT’s largest labs, had more than 250 people working across seven buildings when he took the helm. He was a professor of physics and nuclear science and engineering.

Prior to the discovery of Neves Valente's body, police in Providence said the DNA of the Brown University suspected shooter had been gathered, and images and video of the person of interest matched eyewitness descriptions.

A person of interest was initially detained last weekend before law enforcement determined they had the wrong individual.

The Brown University students who were killed and wounded Saturday were studying for a final in a first-floor classroom in an older section of the engineering building when the shooter walked in and opened fire, WCVB said.

Sophomore Ella Cook, 19, and freshman Mukhammad Aziz Umurzokov, 18, were killed in the shooting, the station said.

Cook, whose funeral is Monday, was active in her Alabama church and served as vice president of the Brown College Republicans, WCVB said, adding that Umurzokov’s family immigrated to the U.S. from Uzbekistan when he was a child and that he wanted to be a doctor.

The station added in regard to the wounded students, six were in stable condition Thursday, and the other three had been discharged.
