Claudio Manuel Neves Valente, the suspect in the deadly December shooting at Brown University and the death of a Massachusetts Institute of Technology professor just two days later, left behind confessional videos, according to the U.S. Attorney’s Office for the District of Massachusetts.

Investigators executed a federal search warrant at a storage facility used by Neves Valente, 48, on Dec. 18, 2025, according to a press release issued by the U.S. Attorney’s Office on Tuesday, Jan. 6.

During the search, officials say that investigators found a series of short videos made by Neves Valente after the shootings.

“In these videos, Neves Valente admitted that he had been planning the Brown University shooting for a long time,” the press release alleges. “Although Neves Valente stated that Brown University was his intended target, based on initial review of the evidence collected, he did not provide a motive for targeting students at Brown University or the professor at MIT.”

As previously reported by PEOPLE, two people were killed, and nine others were injured, in a shooting at Brown University on Dec. 13, 2025. The two people who were killed in the attack were later identified as Mukhammad Aziz Umurzokov and Ella Cook, 19.

Two days later, on Dec. 15, 2025, Nuno F. G. Loureiro, 47, a professor at MIT, was found with apparent gunshot wounds at his Brookline, Mass., home. He was pronounced dead the morning after.

On Dec. 18, 2025, it was announced that Neves Valente was found dead from a self-inflicted gunshot wound in a storage facility in New Hampshire.

“Neves Valente showed no remorse during the recordings; on the contrary, he exposed his true nature when he blamed innocent, unarmed children for their deaths at his hand and grumbled about a self-inflicted injury he suffered when he shot the MIT professor at close range,” the press release continued.

Although an investigation into the motives behind Neves Valente’s alleged actions continues, the Department of Justice released transcripts of the short videos made by Neves Valente, translated from Portuguese to English, with the press release.

In a portion of the translated transcript, Neves Valente allegedly said, “I’ve been here… I’ve been here without caring for a very long time now. To say that I was extraordinarily satisfied, no, but I also don’t regret what I did. Honestly, my only regret is this thing in the eye [laughs]. But it was really hard, man.”

He also acknowledged that his attack at Brown University, in which he was briefly enrolled as a graduate student in the physics department in the early 2000s, didn’t go as planned.
