On December 15th, 2025, Brown University and its surrounding community suffered a violent act at the hands of a troubled alumnus. The gunman entered a classroom in the Barus and Holley building and took two innocent lives and wounded nine others. He then allegedly traveled to Brookline, Massachusetts, targeting MIT professor Nuno Loureiro, and shot him at his home.
Investigators claim the gun that killed Loureiro was a different gun used in the Brown shooting, both 9mm, which were found on Valente. They have also found security footage that confirmed Claudio had entered Loureiro’s apartment building before eventually ending up at an Extra Space Storage facility in Salem, New Hampshire, to take his own life. Multiple sources claim that Valente’s motivation stems from a “lengthy grudge.”
What makes Valente’s confession tapes so interesting is that they were recorded after the shootings occurred. It seems more common for mass shooters to create their confessions or manifestos before the act because more often than not, the shooter intends not to live on after their act of violence.
Other recent instances of high-profile shooters outliving their act of violence are Nikolas Cruz and Ethan Crumbley. Nikolas Cruz, who shot and killed 17 people in 2018 at a Parkland high school, was caught by police hours after the shooting, and Ethan Crumbley, who shot and killed 4 people at a Township high school in 2021, surrendered to law enforcement just minutes after the act. He left many written and visual recordings evidencing his mental decline and motivations before the shooting. Both shooters certainly had different underlying causes that led them to commit such heinous acts, though they do share common themes in their confessions. They shared pre-incident detachment and lack of remorse, and post-incident remorse and guilt. They also shared a specific admission of their motive, which was, to oversimplify it, to make others suffer, and an acknowledgment of their declining mental health.
Unlike the previous examples, Valente, to my knowledge, had not shared any pre-incident indications. He was also not caught or interviewed by law enforcement. His confession was voluntary, which should eliminate the coercive influence that can impact a police interrogation. The transcripts resemble a defensive narrative or a loose confession more than a manifesto, which is regularly tied to mass shooters (Ethan Crumbley created a manifesto before his act).
Manifestos typically outline the purpose behind the act, which is often ideologically motivated, and employ persuasive and unifying language. They are more prominent in shooters with extreme ideological motivations, such as Dylan Roof, John Earnest, Patrick Crusius, and Brenton Tarrant. In 2007, I was attending high school on the East Coast of Virginia when Virginia Tech was subject to a mass shooting, which claimed 32 lives. The shooter, Seung-Hui Cho, left behind a wordy manifesto which also contained photographs. Seung-Hui Cho’s manifesto rambled themes of hatred, desire for vengeance, victimhood, and a desperate need for control, which all align with defining aspects of a manifesto. There was, however, a lack of reasoning for the choice of victims and location.
The transcripts of Valente’s tapes are mostly translations since Valente spoke Portuguese for most of his confession. Anyone who has learned a foreign language or who has taught foreign languages can understand the risk of translation. There is an area of interpretation that needs to be taken into account when translating material, as there are expressions and nuanced verbiage that cannot be directly translated. So, any analyses of the transcripts from Valente’s confessions must consider the possibility of misinterpreted translation.
This post presents a forensic linguistic analysis of the translated transcript of Caludio Valente’s confession tapes and will apply principles of statement analysis to find patterns of narrative construction and strategies. The transcripts are allegedly verbatim from these unseen videos. Analysis is provided for understanding what exactly Valente is confessing and any indicators of motivations or who he intended his audience to be.
Overall assessment: Highly likely cognitive and emotional overload, agentive positioning, moral disengagement, strategic omission, and adversarial audience construction.

Pronoun Positioning
The entire narrative has an extremely high frequency of “I,” which demonstrates ownership and narrative control. This shows the agency of the speaker, whereas in assessments of courtroom testimonies, there tends to be a lack of “I” when the speaker is feeling guilt and wants to create distance between themselves and the scene.
“You” is treated non-specifically, which will become an ongoing theme in this assessment. There are also out-group exclamations, verbal aggression, such as “go fuck yourselves.” This constructs a polarized moral reality where “I” represents a lucid actor and “you” represents the hypocritical and undeserving.
“They” also come into the mix when Valente refers to the victims as “these people” and even further dehumanizes the victims by merging them into an inconvenient mess by using phrases like “all of this shit”. It erases the victims, reducing them to part of the circumstances rather than beings.
“We” is used only twice. Once when discussing the people he had spoken to in private, and again after thanking his viewers for “the opportunity”. Valente says, “We are finished”. There are a couple of things odd with this statement. If the translation and interpretation are solid, the use of “we are finished” in an American English context is often used to signify the completion of a task, or it is used to signify a dramatic end or defeat. Oddly, Valente has shown a significantly strong sense of ownership when it comes to his actions; he does not involve an “us” or “we” in his statements. It seems unnatural for him to use “we” when referring to a task he previously took responsibility for. And if he is dramatizing his sense of dread, then why does he include the viewers, since that was the last “you” he was speaking of? Over and over, he states that he wants to go out on his own terms; it would have been more natural to say “I’m finished”.
Omission
Valente owns the actions with phrases like “it happened” and “mistakes were made”. However, there is a lack of what exactly happened. For example: “It was hard as hell to do it to all of these people”. To “do it” suppresses the content.
Threat to Identity
Valente demonstrates several linguistic features that he senses the pressure of judgment. His narrative is dense with sensitivity markers, which typically indicate internal rehearsal of counterarguments and a need for explanation. Sensitivity markers can be found with uses of “because”, “since”, “so”, “that’s why”, and so on.
His repeated insistence, “I am sane,” is contradicted by the disorganized sequencing of his narrative, temporal confusion, which could be due to his cognitive and emotional overload, as well as what could be a debilitating eye injury. His repetition of sanity is another attempt to secure his identity and the perception that others have of him.
Stance Inconsistency
There are also noticeable contradictions in Valente’s transcripts. He claims multiple times that he doesn’t care when he otherwise continues stating his justifications and his concern about how they are interpreted.
Hedging
Valente’s use of hedging is less significant here, as hedging is often more noteworthy in courtroom testimonies when facts become suppressed into opinions. Valente’s use of these indicators, such as “basically”, “probably”, and “kind of”, is most likely an honest formulation of opinion and not intentionally transforming a factual event into an impression.
Stress Markers
Examples:
- “It was, it was…”
- “And—and it’s—it’s…”
- “There isn’t—there isn’t—there isn’t…”
Such repetition, which also dominates the narrative, can indicate cognitive overload and emotional arousal. These repetitions often occur around Valente’s moral justifications, the confrontation, and his eye injury.
This cognitive overload and perhaps even executive fatigue are further shown in his system breakdowns, where he becomes present-moment focused and goes into sensory narration such as “the lights…” and “my eye…”.
Discussion
What makes Valente’s narrative so unsettling is the disturbing lack of remorse and specificity. There is no denial of committing an act of violence, but there’s a deliberate omission of what those acts specifically were and why they were done. It’s especially odd considering he specifically targeted Loureiro at his home, over an hour’s drive away from Brown University.
The question currently remains unanswered about what emails Valente sent and what they contained. Also, why did he target Brown University? Why Nuno Loureiro? Linguistic evidence points to feelings of betrayal and fatigue more than envy. Valente employs “envy” in the context of those who can carry out violence and end their own lives. He does not mention envy toward Nuno Loureiro, which has been suggested by some sources as his motivation. His sentence “That is what I really envy” may be a nod confirming some feelings of jealousy toward something else, or it could function as another response to the rumors, as it is evident he was keeping tabs on the news.
Some questions are answered in the first video, where Valente begins a vague explanation of his actions: “This was an issue of… of opportunity. I would really like to thank you for the only opportunity that you gave me here, which was this one, and… and look, that’s it. I don’t have anything else to say. We are finished.” As mentioned earlier, the “you” is ambiguous and could mean the audience as one person or all the way to the whole world. The opportunity he is thanking the audience for is most likely for watching his video, the opportunity of being listened to.
More information unfolds in the second video. Valente adds: “I needed a catalyst–for both of them. But for the first one, it was the fact that I was confronted, and in the second, I also had one, you could say, a little bit.” He admits to relying on a catalyst. The omission of detail for the second catalyst suggests that it may risk the narrative he is constructing. His word choice of “catalyst” is also interesting; it is defined as a person or thing that precipitates an event. Valente, crediting the confrontation with that other man on campus for prompting his attack on Brown University, opens the possibility that something or someone else prompted Valente’s targeting of Nuno Loureiro. His first catalyst is specified by his first-hand experience (“I was confronted”), while his second catalyst is minimized; Valente reduces ownership and does not contribute a first-hand reasoning or experience.
His resentment seems directed toward people in general, not just Americans, and not even those he specifically targeted. This resentment may have been catalyzed by his earlier account of feeling perhaps humiliated or betrayed: “I later had access, uhm, to the people privately, the conversations we had privately showed it was all fake. Uhm [pause] so they are not going to get anything from me. I did not like any one of you. I saw all of this shit from the beginning.” He was apologized to before, and later it was revealed that these apologies were not genuine, perhaps due to formalities often used in formal disputes or other reasons. The function of “you” seems to shift from the viewers to those who wronged him.
His videos function as a suicide note, and the content, especially when we consider their chronology, does not entail a confessional revelation nor a manifesto. It resonates a narrative constructed for the audience, correcting rumors and clarifying his lack of feeling. The chronology of his videos shows how much he prioritized how his audience would perceive him. His first video encompasses a defensive narrative establishing his lack of remorse, his intention of “leaving on his own terms”, and the vague explanation as to why he was led to commit such acts. It is in the second video that he begins to touch on what he said in his previous video, adding more resentment toward others. His third video enforces that he is a reliable narrator, repeating that he is sane, and as if to prove that he is not an ego-driven maniac, declares that he does not want to leave a legacy or manifesto and “does not care” what others think (which is ironic). His final video is prompted by his need to correct rumors claiming that he said “Allah Akbar” during the attacks. What mattered most to Valente before his death was control of his narrative.
