RI - Mass Shooting at Brown University - Providence 13 Dec 2025

If you planned to kill yourself why would you bother to return the rental car?

He didn’t return the rental car. It was at the storage unit. He returned a previous rental car before getting the Nissan.

Got him! I feel the Investigators should have worked backwards from the gray Nissan seen in Brookline, to searching for a similar car in the Brown parking lot. Cameras?

If you planned to kill yourself why would you bother to return the rental car?

did he return it? Or did he just park near to his storage unit where he decided to kill himself?

I don’t think the backend of what happened was really planned - he likely expected to be shot dead by police at the school.

I think then after a couple of days he realised the police had very little information on him so decided it was safe to go and kill his intended target - The Professor IMO.

Then following that he killed himself imo - I believe he was probably dead from the evening of the professors attack moo.

Those claims from Noem should probably be verified. Hopefully the news media can fact check.

There are some information about Claudio Neves Valente and the Green Card lottery in this Portuguese newspaper article, translated into English with Google Translate:

O que se sabe sobre Cláudio Valente, o português suspeito do tiroteio em Brown e homicídio de professor do MIT

Cláudio Valente, de 48 anos, ex-aluno em Brown, identificado como autor dos ataques, foi encontrado morto com um ferimento de bala auto-infligido.

www-publico-pt.translate.goog

He seems to have been a quite brilliant student in his teens, from the article above:
What is known about Cláudio Valente, the Portuguese man suspected of the Brown shooting and the murder of an MIT professor?

Here's what we know about Cláudio Valente, 48 years old.​

• He studied at Maria Lamas Secondary School in Torres Novas. He was considered a brilliant student in physics. At age 17, he was one of five students selected for a national competition.
• According to a 1995 excerpt from Gazeta de Física , the official publication of the Portuguese Physics Society, which PÚBLICO had access to, Cláudio Valente represented Portugal at the International Physics Olympiad (IPhO), which took place in Canberra, Australia, that year, along with four other students from other schools.
• Between 1995 and 2000, he studied at the Instituto Superior Técnico in Lisbon, the same university where MIT professor Nuno Loureiro studied Physics. Authorities believe Valente and Loureiro knew each other, but have not released further details.

Ahh, well never mind my car-based speculation then lol.


Has anyone got a basic timeline of events for both shootings? I don't feel like I have the order of events and their dates/times/locations clear in my head for this one.
Cheers

It has always fascinated me when these criminals go to great lengths to escape and THEN decide to off themselves.
It makes sense when they do it as authorities are closing in, to avoid capture in the moment, but this guy got to the storage facility three days ago.
I'm really curious about the efforts some of these people make to maintain complete control, and then go ultimately do themselves in anyway.
There are some papers in the literature about "psuedocommando" killers who anticipate going out mid-assault, but it's not quite as clear why some fight hard get away (and then suicide), and some want it to end in the middle of their attack. Just a strange, strange nuance among these creeps.

maybe the ultimate goal was to kill himself...
And he just wanted to settle some grudges first.

US to pause diversity visa after Brown shooting suspect identified as green card holder from program​

From CNN's Xiaoqian Lin

The United States’ immigration agency has been directed to pause its diversity visa lottery program (DV1) after the suspect in the Brown University shooting was found to have entered the country via the scheme, said Secretary of Homeland Security Kristi Noem.

Claudio Valente entered the United States through the diversity lottery immigrant visa program in 2017 and was granted a green card, said Noem in an X post on Thursday night.

“This heinous individual should never have been allowed in our country,” she added.
“At President Trump’s direction, I am immediately directing USCIS to pause the DV1 program to ensure no more Americans are harmed by this disastrous program.”
Valente, the deceased suspect, was a 48-year-old former Brown University student and Portuguese national.

Under the diversity visa program, up to 55,000 immigrants can enter the United States each year from countries with low rates of immigration to the US, according to the State Department’s website.

The talented professor in Boston who was killed was from Portugal too. This change in policy seems like throwing out the baby with the bathwater.

I thought the professor died first tbh. If Nuno Loureiro was his primary target, it doesn't make sense to me that he would shoot up Brown first. In almost all cases, especially high profile ones. They're killed/caught/commit suicide on scene or pretty soon after, often it's over in minutes. It's pretty rare for a school shooter to get clean away (though it's happened a few times this year). He would have to be fully delusional to plan this expecting to escape and evade capture for days.

I would have thought, if the most important thing to him was to kill Nuno Loureiro. He'd have made sure to do that first, then gone to Brown for his (it seems) far more indiscriminate attack.

Why did he have a storage unit in Salem NH? I'm curious if he had a grudge against Dartmouth as well, but got wind that LE was chasing him so aborted mission.

Almost all countries in the world seems to be able to participate, from all continents. I'm not sure that the true reason to pause the lottery is just this case, there might have been plans to do that earlier.

I see nothing that he came over on green card lottery.

When Claudio Neves Valente came to study at Brown University in 2000 he didn't come over on a Green Card Lottery ticket, as he got the Green Card in 2017, and that granted him the right to live and work permanently in the United States. I would guess that both Neves Valente and Nuno F Gomes Loureiro came to the US for studying in the early 2000s with the same kind of student visa.

Nuno Loureiro - Wikipedia

en.wikipedia.org

After graduating, Loureiro joined Princeton University as a postdoctoral researcher at the Princeton Plasma Physics Laboratory in 2005. He left in 2007 to work at the Culham Centre for Fusion Energy, a laboratory under the UK Atomic Energy Authority, until 2009. He returned to Portugal as a researcher at the Instituto de Plasmas e Fusão Nuclear at IST Lisbon for seven years.[1]

The first decent videos and photos of the shooter were released on Monday. I wonder if that made him panic and just go ahead and kill the intended overall target, the MIT professor, and then himself. There may have been a plan to conduct the shooting at Brown and then a similar one at MIT (involving the professor) to hide the connection. Then he realized the walls were closing in fast and that was impossible, so plans changed.

The plans to end/pause the program might have been in the works, but the messaging is action taken now to pause the program is because of this case. The professor who was killed was from the same country as his killer.

U.S. Department of Homeland Security Secretary Kristi Noem said she was suspending the diversity visa program, saying the man suspected of killing two students at Brown University had been granted one.

Sometimes, what's not being said is more interesting than what is. What has Claudio Valente been doing for the last 25 years? There doesn't seem to be anything on any media source, which seems rather strange, because you would think that the entire news media would be looking for background info on his past, but nobody has published anything. No former colleagues seem to have contacted the press about him. Nothing.

Even after dropping out of Brown, he still had a good degree from a good university back in Portugal. He should have been able to use that to get a foot in the door somewhere. So, what has he been doing?

 

[Elley Mae]

Snipped

Following the 2017 truck attack in New York City, carried out by a diversity visa recipient, Trump sought to end the program, claiming it allowed “the worst of the worst” to enter the U.S.

MSN

While the DV program has been temporarily suspended, its future remains uncertain. Former President Joe Biden reinstated the program in 2021 after it was briefly halted during Trump’s first term.

Grace Eliza Goodwin
Live reporter

If you're just joining us, we are waiting for word from officials in Providence. Rhode Island as to the latest in the investigation into Saturday's shooting at Brown University.

Here's what we know about the timeline of events on that day and what has happened since.

Well what do you expect them to do? Gun reform? What do you think this is, Australia? Honestly.

There have been 398 mass shoohtings (4+ shot) in 2025, 4 since this happened last Saturday. Roughly 14% of mass shooters are foreign born, exactly proportional to demographics. So if you ban all the immigrants, next year there would be only... 333 mass shootings. Which would be a decisive improvement. Let it not be said American does nothing in the face of (more than) daily indiscriminate murder!

Of course, the insane thing of is that 398 is actually a significant improvement. In 2024 there was 650 (down from the COVID peak of 693 in 2021.)

Since (and including) the Port Arthur Massacre 30 years ago, Australia has had 4 mass shootings by the same criteria btw. Yet their government is promising a comprehensive review/reinforcement of the current legislation in the wake of the Bondi Beach attacks. A national gun register, tighter/renewal background checks, limiting licenced guns per person etc.... What pussys hey? One little beach slaughter and the government runs around like you can just 'do reforms' and 'reduce gun violence. Expecting ordinary Australians to be accountable for their firearms. Or worse... denied! Just for being 'dangerous' or 'crazy' or a 'terrorist.' And most of the public are fine with that trade-off! SMH.


/S if it is not blindingly obvious.
