• Claudio Neves Valente, 48, was identified as the suspect in a mass shooting at Brown University.
• Two students were killed and several others injured during the Dec. 13 attack.
• Valente also allegedly killed MIT professor Nuno F.G. Loureiro two days later.
• He was found dead by suicide in a New Hampshire storage unit.
• Authorities are investigating the motive behind his actions.

Claudio Neves Valente, a 48-year-old former graduate student at Brown University, has been identified as the suspect behind the December 13 mass shooting that left two students dead and nine others injured. This incident occurred during a study session at the Barus & Holley Engineering Building. Following his identification, Valente was also linked to the fatal shooting of MIT professor Nuno Loureiro two days later, prompting a multi-state manhunt. Valente's body was later discovered in a New Hampshire storage unit, where he died from a self-inflicted gunshot wound, according to authorities. The autopsy confirmed the cause of death and estimated that it occurred on December 15, before his body was found two days later, according to AA.

Authorities believe Valente acted alone in both attacks. After conducting investigations, it was revealed that he had been a student at Brown from 2000 to 2001 before ultimately withdrawing from the program in 2003 due to unspecified reasons. Brown University President Christina Paxson stated that Valente had no active affiliation with the university at the time of the incidents. Notably, investigators have not yet found a clear motive for his violent actions, with ongoing examinations of his recent activities revealing limited insights, as stated by the New Hampshire Attorney General John M. Formella and corroborated by Reuters, ABC News, and LA Times.

Claudio Valente had a history as a promising student before his downfall; he was recognized for his academic brilliance at the Instituto Superior Técnico in Lisbon, Portugal, where he studied alongside Loureiro. Colleagues and former classmates noted that while he was admired for his intelligence, he often exhibited signs of frustration and anger, making it difficult to comprehend his violent actions later in life. These insights were highlighted by various reports from those who remembered him as "brilliant" but sometimes angry, indicating a significant change in his demeanor since his academic days, according to insights from ABC News and Reuters.

The two victims of the Brown attack were identified as Ella Cook and Mukhammad Aziz Umurzokov, both of whom were engaged in their studies when the shooting occurred. Their deaths have sent shockwaves through the campus and grieving community. In addition to the fatalities, several others were injured but are in stable condition. Investigators have referenced eyewitness accounts and surveillance footage in an attempt to piece together the events leading up to the shootings, with a comprehensive review of available data ongoing, as cited by LA Times and Reuters.
