Transcripts released by the Department of Justice reveal Claudio Neves Valente, the shooter in the Brown University attack and killer of an MIT professor, admitted to planning the violence for years. Valente, a Portuguese national found dead from a self-inflicted gunshot wound, expressed no remorse in recorded videos. He denied mental illness and addressed misinformation about his actions, stating he did not yell 'Allahu Akbar.' The investigation into his motives is ongoing.
