PROVIDENCE, R.I. – Authorities have concluded a tense manhunt for the suspect in last weekend’s mass shooting at Brown University. The search ended dramatically at a storage facility in New Hampshire, where police discovered the suspect deceased and linked him to another tragic crime involving a Massachusetts Institute of Technology (MIT) professor.

Claudio Neves Valente, 48, was identified as the suspect. A former student at Brown University and a citizen of Portugal, Valente was found dead Thursday night, having suffered a self-inflicted gunshot wound, according to Providence Police Chief Col. Oscar Perez.

Investigative teams have connected Valente to the deadly shooting that took place last Saturday in a lecture hall at Brown University, where two students lost their lives and nine others were injured. Furthermore, he is believed to have murdered MIT professor Nuno F.G. Loureiro two days later at the professor’s residence in the Boston suburbs, located almost 50 miles from Providence. Chief Perez confirmed that investigators currently have no evidence of any accomplices, suggesting Valente acted independently.

Brown University President Christina Paxson provided context on Valente’s background, stating that he had been enrolled as a graduate student in physics from the fall of 2000 through the spring of 2001.

“He has no current affiliation with the university,” Paxson clarified.

Neves Valente and Loureiro previously attended the same academic program at a university in Portugal between 1995 and 2000, U.S. attorney for Massachusetts Leah B. 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.

Neves Valente had come to Brown on a student visa. He eventually obtained legal permanent residence status in September 2017, Foley said. It was not immediately clear where he was between taking a leave of absence from the school in 2001 and getting the visa in 2017. His last known residence was in Miami.

After officials revealed the suspect’s identity, President Donald Trump suspended the green card lottery program that allowed Neves Valente to stay in the United States.

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.

Tip helps investigators connect the dots

The FBI previously said it knew of no links between the Rhode Island and Massachusetts shootings.

Police credited a person who had several encounters with Neves Valente for providing a crucial tip that led to the suspect.

After police shared security video of a person of interest, the witness — known only as “John” in a Providence police affidavit — recognized him and posted his suspicions on the social media forum Reddit. Reddit users urged him to tell the FBI, and John said he did.

John said he had encountered Neves Valente hours earlier in the bathroom of the engineering building where the shooting occurred and noticed he was wearing inappropriate clothing for the weather, according to the affidavit. He again bumped into Neves Valente a couple blocks away and saw him suddenly turn away from a Nissan sedan when he saw John.

“When you do crack it, you crack it. And that person led us to the car, which led us to the name,” Neronha said.

His tip pointed investigators to a Nissan Sentra with Florida plates. That enabled Providence police 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, Providence officials said Neves Valente stuck a Maine license plate over his rental car’s plate to help conceal his identity.

Investigators found footage of Neves Valente entering an apartment building near Loureiro’s in a Boston suburb. About an hour later, Neves Valente was seen entering the Salem, New Hampshire, storage facility where he was found dead, Foley said. He had with him a satchel and two firearms, Neronha said.

Victims include renowned physicist, political organizer and aspiring doctor

Loureiro, a 47-year-old physicist and fusion scientist, had joined MIT in 2016 and was named last year to lead the school’s Plasma Science and Fusion Center, one of its largest laboratories. The scientist from Viseu, Portugal, had been working to explain the physics behind astronomical phenomena such as solar flares.

The two Brown students killed during a study session for final exams were 19-year-old sophomore Ella Cook and 18-year-old freshman MukhammadAziz Umurzokov. Cook 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, three had been discharged and six were in stable condition Thursday, officials said.

Although Brown officials say there are 1,200 cameras on campus, the attack happened in an older part of the engineering building that has few, if any, cameras. And investigators believe the shooter entered and left through a door that faces a residential street bordering campus, which might explain why the cameras Brown does have didn’t capture footage of the person.
