Portuguese national Claudio Neves Valente, who killed two Brown University students and an MIT professor in recent shootings, was connected to the MIT victim from 30 years ago in Portugal. Authorities said Neves Valente met Nuno Loureiro between 1995 and 2000 at Portugal's Instituto Superior Técnico. “My understanding is that they did know each other,” US Attorney Leah Foley said. Valente came to the US on a student visa in 2000 to join a doctoral program at Brown, but left by 2003 with no current ties. He became a US permanent resident in 2017. Weeks before the shootings, he rented a storage unit in Salem, New Hampshire, and a Boston hotel room. On December 1, he rented a grey Nissan Sentra, seen near Brown’s campus multiple times. On Saturday, he killed Brown students Ella Cook and Mukhammad Aziz Umurzokov, wounding nine others. He then changed the car’s plates and on Monday fatally shot Loureiro at his home in Brookline. Authorities found Valente dead from a self-inflicted gunshot inside the storage unit, ending a nearly weeklong manhunt.
