Videos recorded after a deadly campus rampage show the gunman coldly confessing he “chickened out” of earlier opportunities and blaming students for their own deaths.
The Discovery
Federal agents executed a search warrant at a New Hampshire storage facility on Dec. 18, 2025, the same day Claudio Manuel Neves Valente was found dead from a self-inflicted gunshot wound.
Inside the unit, investigators seized short videos the 48-year-old made after the attacks. In them, he admits:
- Planning the Brown University assault “for a long time”
- Preferring a smaller room over the auditorium where he ultimately opened fire
- Regretting only an eye injury he suffered while shooting the MIT professor
Victims and Timeline
| Date | Incident | Fatalities |
|---|---|---|
| Dec. 13, 2025 | Brown University shooting | 2 (Mukhammad Aziz Umurzokov, Ella Cook, 19) |
| Dec. 15, 2025 | MIT professor killed in Brookline | 1 (Nuno F. G. Loureiro, 47) |
| Dec. 18, 2025 | Suspect found dead | – |
Neves Valente briefly attended Brown’s physics graduate program in the early 2000s. Nine others were injured in the campus attack.
What the Videos Reveal
A translated transcript released by the U.S. Attorney’s Office captures his matter-of-fact tone.
> “I’ve been here without caring for a very long time now. To say I was extraordinarily satisfied, no, but I also don’t regret what I did. Honestly, my only regret is this thing in the eye.”
He laughed, then added, “But it was really hard, man.”
Prosecutors note the recordings offer no clear motive for targeting Brown students or the MIT professor.
Key Takeaways
- Neves Valente staged two fatal attacks within 48 hours
- Videos show calculated planning but no remorse
- Authorities continue to analyze evidence for a definitive motive
- The Dec. 18 discovery of the confession clips closes the manhunt but leaves the community searching for closure
Families of the three victims now grapple with both the brutality captured on tape and the unresolved question of why.
