Cláudio Manuel Neves Valente (January 22, 1977 – December 16, 2025) was born in Torres Novas, Portugal. He studied at the same university as Loureiro, the Instituto Superior Técnico in Lisbon, in the late 1990s.
After graduating first in his class from the school ahead of Loureiro, he enrolled in the physics PhD program at Brown University in the fall of 2000. He took a leave of absence in April 2001 and formally withdrew from the doctoral program in July 2003. Valente lived in Providence during his time at Brown. Former classmates at the Instituto described him as a very high achiever who however kept hostile relationships with the rest of the class due to his need to affirm his superiority. According to Scott Watson, a physics professor at Syracuse University and a close friend and former classmate at Brown, Valente "was often unhappy and even angry, complaining that classes were too easy and that the food on Brown's campus was subpar" during the time they were both doctoral students.
After leaving Brown, Valente returned to Portugal, working as an IT specialist for SAPO. He later won the Diversity Immigrant Visa lottery, obtaining U.S. permanent residency in April 2017. He had no criminal record. His last known address was in the working-class neighborhood of Ives Estates, Florida. Beginning on November 28, 2025, he was observed on the Brown campus by multiple people who found his behavior suspicious.
On December 18, 2025 with an arrest warrant police went to a storage facility in Salem, New Hampshire, and found 48-year-old Cláudio dead inside. Two guns were found on his body and it was clear he had killed himself. The autopsy found that he had been dead for two days.
