WASHINGTON — A man linked to a deadly shooting spree at Brown University, which resulted in two deaths and several injuries, was discovered deceased in a New Hampshire storage unit he had rented, according to officials.

Claudio Neves Valente, 48, a Portuguese national and former student of Brown, was found dead Thursday evening from what appeared to be a self-inflicted gunshot wound, announced Col. Oscar Perez, the Providence police chief, during a press briefing. Perez confirmed that current evidence suggests Valente acted independently.

Law enforcement believes Valente is accountable for both the Brown University shooting and the murder of an MIT professor, who was shot and killed at his Brookline residence earlier in the week, according to a source speaking to The Associated Press. However, authorities have not officially linked the two crimes.

The source, who provided information on the condition of anonymity due to the ongoing investigation, was not authorized to disclose further details publicly.

Brown University President Christina Paxson said 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.

Two people were killed and nine were wounded in the mass shooting Saturday at Brown University. The investigation had shifted Thursday when authorities said they were looking into a connection between the Brown mass shooting and an attack two days later near Boston that killed MIT professor Nuno F.G. Loureiro.

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

A second individual who was identified in proximity to the suspect came forward after Wednesday’s press conference and helped “blow the lid” off the case, Rhode Island Attorney General Peter Neronha said.

“When you crack it, you crack it. That person led us to the car, led us to the name,” Neronha said.

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

Frustration had mounted in Providence that the person behind the attack managed to get away and that a clear image of their face hadn’t emerged.

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.

In such targeted and highly public attacks, the shooters typically kill themselves or are killed or arrested by police, said Katherine Schweit, a retired FBI agent and expert on mass shootings. When they do get away, searches can take time.

In the 2013 Boston Marathon bombing, it took investigators four days to catch up to the two brothers who carried it out. In a 2023 case, Army reservist Robert Card was found dead of an apparent suicide two days after he killed 18 people and wounded 13 others in Lewiston, Maine.

The man accused of killing conservative political figure Charlie Kirk in September turned himself in about a day and a half after the attack on Utah Valley University’s campus. And Luigi Mangione, who has pleaded not guilty to murder charges in the killing of UnitedHealthcare CEO Brian Thompson in Manhattan last year, was arrested five days later at a McDonald’s in Pennsylvania.

Loureiro, 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.

He grew up in Viseu, in central Portugal, and studied in Lisbon before earning a doctorate in London, according to MIT. He was a researcher at an institute for nuclear fusion in Lisbon before joining MIT, the university said.

“He shone a bright light as a mentor, friend, teacher, colleague and leader, and was universally admired for his articulate, compassionate manner,” Dennis Whyte, an engineering professor who previously led MIT’s Plasma Science and Fusion Center, told a campus publication.

Loureiro had said he hoped his work would shape the future.

“It’s not hyperbole to say MIT is where you go to find solutions to humanity’s biggest problems,” Loureiro said when he was named to lead the plasma science lab last year. “Fusion energy will change the course of human history.”
