What to know about the man authorities say fatally shot 2 Brown students and a MIT professor

PROVIDENCE, R.I. (AP) — Investigations into the Brown University mass shooting and the slaying of a Massachusetts Institute of Technology professor shifted Thursday when authorities discovered evidence they say indicates they were committed by the same man, who was then found dead from a self-inflicted gunshot wound.

The attacker at Brown killed two students and wounded nine others in an engineering building on Saturday. Some 50 miles (80 kilometers) away MIT professor Nuno F.G. Loureiro was killed Monday night in his home in the Boston suburb of Brookline.

The FBI had earlier said it knew of no links between the cases.

Here are some answers to questions about the attacks and investigations:

Suspected shooter attended Brown 25 years ago

Claudio Neves Valente, 48, a former Brown student and Portuguese national, was found dead in a New Hampshire storage facility after a six-day search that spanned several New England states.

Brown University President Christina Paxson said Neves Valente was enrolled at Brown from the fall of 2000 to the spring of 2001. He was admitted to the graduate school to study physics beginning in September 2000.

“He has no current affiliation with the university,” she said.

Neves Valente had studied at Brown on a student visa. He eventually obtained legal permanent residence status in September 2017. His last known residence was in Miami.

There are still “a lot of unknowns” in regard to motive, Rhode Island Attorney General Peter Neronha said. “We don’t know why now, why Brown, why these students and why this classroom,” he said.

Attended the same university as Loureiro in Portugal

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.

Valente and Loureiro attended the same academic program at a university in Portugal between 1995 and 2000, Foley said. Loureiro graduated from the physics program at Instituto Superior Técnico, Portugal’s premier engineering school, in 2000, according to his MIT faculty page.

The same year, Neves Valente was let go from a position at the Lisbon university, according to an archive of a termination notice from the school’s then-president in February 2000.

Identifying a suspect

Authorities released several security videos of a person thought might have carried out the Brown attack. They showed the individual standing, walking and even running along the streets, but their face is masked or turned away in all of them.

Police say a witness then gave investigators a key tip: he saw someone who looked like the person of interest with a Nissan sedan displaying Florida plates. That enabled Providence police officers to tap into a network of more than 70 street cameras operated around the city by surveillance company Flock Safety. Those cameras track license plates and other vehicle details.

After leaving Rhode Island for Massachusetts, Providence officials said the suspect stuck a Maine license plate over the rental car’s plate to help conceal his identity.

Video footage showed Neves Valente entering an apartment building near Loureiro’s. About an hour later, he was seen entering the New Hampshire storage facility where he was later found dead, Foley said.

Slain Brown students were a freshman and sophomore

The two students who were killed and the nine others wounded 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.

Those killed were 19-year-old sophomore Ella Cook and 18-year-old freshman MukhammadAziz Umurzokov. Cook, whose funeral is Monday, was active in her Alabama church and served as vice president of the Brown College Republicans. Umurzokov’s family immigrated to the U.S. from Uzbekistan when he was a child, and he aspired to be a doctor.

As for the wounded, six were in stable condition Thursday, officials said. The other three were discharged.

Suspect’s residency status

Neves Valiente gained permanent residency status through a green card lottery program, Homeland Security Secretary Kristi Noem said in a post on X.

She said President Donald Trump ordered her to pause the United States Citizenship and Immigration Services program.

The diversity visa program makes up to 50,000 green cards available each year by lottery to people from countries that are little represented in the United States, many of them in Africa.

The lottery was created by Congress, and the move is almost certain to invite legal challenges.
