The man accused of carrying out last month’s mass shooting at Brown University that left two students dead admitted to the crime in a series of four videos, the transcripts of which were released Tuesday by the U.S. Attorney’s Office for the District of Massachusetts. 

Claudio Neves Valente, the 48-year-old suspect who previously attended Brown, was found dead by a self-inflicted gunshot wound at a storage facility in New Hampshire just days after the campus attack, preventing investigators from interrogating him. But in the videos, which were pulled from an electronic device at the storage facility and have been translated from Portuguese to English, Valente admitted to the Brown shooting and the subsequent killing of a Massachusetts Institute of Technology professor near Boston. 

And while the suspect said that he would not apologize, the motives of the attack remain unclear.

Throughout the more than 11 minutes’ worth of video, he spoke about how he had planned the shooting for years. In multiple instances, Valente vaguely referenced “the people” his violent actions were made in response to, saying, “I did not like any one of you. I saw all of this shit from the beginning.” 

He noted that he sent three emails, seemingly to “the people” he’d referenced. But beyond that, he was “not saying anything else.”
