The Brown University shooting has ended with the suspect dead, but the aftermath raised odd twists about how he moved, how he was found, and how campus security failed to notice warning signs.
Authorities say the suspect, Claudio Neves Valente, 48, a Portuguese national, was found dead of a self-inflicted gunshot wound in Salem, New Hampshire. He was wanted for the December 13 shooting at Brown University, where two people were killed and nine others were wounded. Officials also linked him to the killing of MIT professor Nuno F.G. Loureiro in Brookline, Massachusetts, and investigators say the same Nissan Sentra was used in both incidents after its plates were changed.
Valente entered the U.S. on a student visa to attend Brown and obtained permanent legal status in September 2017. On December 13 he went into the Barus and Holley Building, Brown’s engineering facility, and opened fire on students during a study session. After that attack he spent time in Massachusetts and later shot Professor Loureiro at his home; reports say Valente and Loureiro knew each other as former classmates in Lisbon. Investigators say Valente rented a storage unit in Salem in November and was found dead in a different unit, with two firearms found on his person.
Officials have not pinned down exactly when Valente took his own life, and questions remain about how he managed to evade detection for days. He used a Google phone loaded with specific apps and possibly European SIM cards, which made tracking his movements difficult. Sources say he knew how to cover his tracks, swapping plates on the vehicle and leveraging tech and tactics that hampered standard location tracing.
Rhode Island and Massachusetts officials held press conferences last night to update the public. U.S. Attorney Leah Foley delivered the briefing about the Brookline killing while state prosecutors and local law enforcement addressed the Brown investigation. The two briefings offered overlapping timelines but left several key questions open, including motive and the suspect’s final movements.
A homeless man identified in coverage as “John” emerged as a critical figure in the search. According to officials, he provided a detailed description of the shooter and the car, and he posted information online that helped investigators narrow down the vehicle capture on nearby cameras. After police released a second person of interest who was in proximity to the incidents, this cooperating witness came forward and assisted fully, which helped lead to Valente’s discovery.
Evidence reviewed by investigators includes vehicle footage and public tips, plus digital traces that were harder to parse. Law enforcement says they matched vehicle descriptions to Flock camera captures after the online post flagged a grey Nissan with Florida plates. That sequence of eyewitness detail, public reporting, and camera checks appears to have been the critical break in the case.
There is also public documentation tied to the case titled “Claudio Manuel Neves Valente Affidavit” by Matt Vespa that outlines parts of the investigative affidavit and timelines. While authorities have released some facts, many pieces of the puzzle remain sealed or under review as investigators piece together the motive and exact chain of events leading up to the killings.
So far, officials say they do not believe antisemitism was a motivating factor and that Valente acted alone. Multiple witnesses reported he shouted, “Allahu Akbar,” before the attack, a detail that Rhode Island Attorney General Peter Neronha declined to clarify further during the pressers. State and local leaders also struggled to answer questions about campus surveillance and security measures at Brown.
Fox News reporting added context about “John,” noting he admitted to sleeping in the basement of the engineering building and that he is reportedly a former Brown student. That revelation undercut assumptions about tight campus security, since a person without stable housing had access to and slept in campus spaces. The account says he followed the suspect out of the building and later posted on Reddit with specifics about the car that matched what police found.
Shocking details that further reveal security issues at Brown University. Why is a homeless man sleeping in the basement of the school building?
A homeless guy and former Brown graduate helped police crack the case. But there is more to the story.
According to my sources, the homeless guy told police he sleeps in the basement of the Barus and Holley building. Earlier in the day, before the shooting, he said he saw the suspect in the basement area and followed him out.
As the homeless guy is trying approach the suspect, he sees him walk toward his car and unlock it. But then he locks it, when he noticed the homeless guy.
After the shooting, the homeless man posted on Reddit saying, “I’m being dead serious. The police need to look into a grey Nissan with Florida plates, possibly a rental.” The post went on to say, “I know because he used his key fob to open the car, approached it and then something prompted him to back away. When he backed away, he relocked the car. I found that odd so when he circled the block I approached the car that is when I saw the Florida plates.”
It was that Reddit post that eventually led police to the shooters car picked up on Flock cameras (police just put in a car description and can track cars captured on flock cameras).
While police credit this man for cracking this case— it still begs the question of what kind of security measures are in place at the Ivy League school, that a homeless person could just be sleeping in basement
Thoughts and prayers go out to the families of Ella Cook and Mukhammad Aziz Umurzokov, the two Brown students killed in the attack.
