Federal investigators are diligently working to unravel the events of a tragic December shooting that resulted in the deaths of two Brown University students and an MIT professor, and left nine others injured, according to authorities.

On Tuesday, officials unveiled transcripts of videos believed to be made by Claudio Manuel Neves Valente, the alleged perpetrator behind the fatal incidents at Brown University and the murder of an MIT physicist.

The shooting on Brown University’s Providence, Rhode Island campus on December 13 claimed the lives of two students: 19-year-old Ella Cook and 18-year-old Muhammad Aziz Umurzokov. Nine others were injured in the attack. Just two days after this incident, Nuno Loureiro, a professor at MIT, was tragically killed in Brookline, Massachusetts.

At this time, authorities report that eight of the wounded Brown students have been discharged from the hospital, while one remains under medical care.

The U.S. Attorney’s Office for the District of Massachusetts provided an image of the suspect involved in these fatal shootings in Rhode Island and Massachusetts, identified as Neves Valente.

Officials from the U.S. Attorney’s Office revealed that on December 18, the FBI executed a federal search warrant at a storage facility associated with Neves Valente, who is a Portuguese national. During the search, they uncovered an electronic device containing several short videos made after the shootings. These videos, originally in Portuguese, were translated into English, and the transcripts were released on Tuesday.

In the recordings, prosecutors said Neves Valente admitted he had been planning the Brown shooting for a long time and said Brown was his intended target. Authorities said he did not provide a motive for targeting Brown students or the MIT professor.

Investigators said the Bureau of Alcohol, Tobacco, Firearms and Explosives traced the gun used in the shootings as part of the investigation.

Officials have not publicly released details about the weapon’s origin or purchase history. Fox News Digital has reached out to the FBI for comment.

Josh Schirard, a former tactical emergency response director at the 2018 Santa Fe High School shooting and director of Byrna Law Enforcement, said the transcripts confirm responsibility for the attack but offer little clarity about why it occurred.

“He understood what he did. He understood that he had a why behind it,” Schirard said. “He just didn’t opine on why that was.”

Schirard said the shooter rejected ideological explanations and denied being mentally ill.

“He even says, ‘I’m not mentally ill. I am very sane, and I did this knowing what I was doing,’” Schirard said.

“He talks about how killing those people was hard,” Schirard said, adding that the shooter said he envied people who could do so “without difficulty.”

An autopsy previously found Neves Valente died by suicide two days before his body was discovered in a storage unit in Salem, New Hampshire.

Authorities said they do not believe there is any ongoing public safety threat associated with the shootings and that additional updates will be provided.
