PROVIDENCE, RI — The shooting suspect connected to the deadly Brown University attack and the fatal shooting of an MIT professor has been found dead in New Hampshire, authorities said late Thursday, ending an exhaustive manhunt that rocked the Ivy League school and the surrounding community.Providence Police Chief Col. Oscar Perez identified the suspected shooter as Claudio Manuel Neves Valente, 48, a Portuguese national who was a former Brown student and whose last known address was in Miami. Perez said Neves Valente took his own life in Salem, New Hampshire, on Dec. 18, and that investigators traced Neves Valente through surveillance footage and a tip that helped police link him to a rented car.Authorities in Massachusetts late Thursday also accused Neves Valente of fatally shooting MIT professor Nuno F.G. Loureiro, 47, on Monday, Dec. 15. Loureiro was found with gunshot wounds at his home in the Boston suburb of Brookline, Massachusetts, about 50 miles north of Brown University."We got him," said Ted Docks, Special Agent in Charge of FBI Boston. "Even though the suspect was found dead tonight, our work is not done."The announcement came after law enforcement officers conducted a dayslong search since the shooting inside a classroom building at the Ivy League institution. At least two people were killed and nine others were injured in the Dec. 13 attack.Rhode Island Attorney General described the investigation as one of the hardest he's been involved with and added that there would be no prosecution in the case."The unthinkable happened in our state, the unthinkable happened at Providence, the unthinkable happened at Brown, and we’re going to be forever changed," said Rhode Island Gov. Dan McKee. "The professionalism that I saw in the law enforcement should make everyone in our state and beyond our borders feel very safe. These things happen, but it requires the professional help of law enforcement to bring it to a conclusion."US to pause diversity visa lottery program after shootingsThe U.S. Citizenship and Immigration Services has been directed to pause its diversity visa lottery program (DV1) after the shooting suspect was found to have entered the country through the program, according to Homeland Security Secretary Kristi Noem.Neves Valente had entered the United States through the program in 2017 and was granted a green card, Noem said in a post on X late Thursday."This heinous individual should never have been allowed in our country," she wrote. "At President Trump’s direction, I am immediately directing USCIS to pause the DV1 program to ensure no more Americans are harmed by this disastrous program."Under the program, up to 55,000 immigrants can enter the country each year from "countries with low rates of immigration to the United States," according to the State Department’s website.Heavy police presence as Brown University shooter search continuesPolice have swarmed a Salem, New Hampshire site as Brown University shooter search intensifies.Suspect attended 'same academic program' as MIT professorNeves Valente, who is believed to have known Loureiro, was found dead with a self-inflicted gunshot wound on Thursday in Salem, New Hampshire, according to Leah Foley, U.S. attorney for the District of Massachusetts.Federal agents "breached" a storage locker that Neves Valente rented in November at around 9 p.m. local time, Foley said during a news conference late Thursday. Investigators believe Neves Valente shot and killed two Brown University students and the MIT professor.According to a court affidavit, Neves Valente and Loureiro attended the same academic program at a university in Portugal from 1995 to 2000. Neves Valente had a student visa while studying at Brown University, and later obtained U.S. lawful permanent residency in April 2017, the Rhode Island Attorney General's office said.Suspect rented Boston hotel room in early DecemberThough Neves Valente appeared to have resided in Florida from Nov. 26 to Nov. 30 of this year, Foley said he rented a hotel room in Boston on Dec. 1. He also rented a grey Nissan Sentra with a Florida license plate from a car rental agency in the city."That same day, he drove to the vicinity of Brown University, where his car was observed intermittently between Dec. 1 and Dec. 12," she said. "On Dec. 13, Neves Valente entered an auditorium on Brown University's campus during a study session and began shooting at students."He then returned to Massachusetts on Dec. 15 and shot and killed Loureiro, according to Foley. While he was in Massachusetts, Neves Valente switched his rental vehicle’s license plates to an unregistered plate from Maine.Neves Valente later drove to the New Hampshire storage facility, where federal authorities discovered his body, according to Foley.Shootings link established 'last 24 to 48 hours'Investigators had established a link between the two shootings in the "last 24 to 48 hours," according to Foley. She noted that the suspect was “sophisticated in hiding his tracks.”He was using a phone that was "obfuscating ability to track it" and credit cards that were not tied to his name, Foley said. Investigators identified the vehicle Neves Valente had rented, which had been captured on surveillance footage."There was financial investigations that were going on in the background that linked him, not only to that car, but also to the hotels that he had rented," Foley said.Shooting suspect identified as former Brown studentNeves Valente attended Brown from the fall of 2000 to spring 2001 before taking a leave of absence, Brown University President Christina Paxson said at a news conference. He was enrolled in a PhD in physics program and formally withdrew from the university in 2003.The deadly attack took place in a building where Neves Valente had classes, according to the university president. "Nothing can fully bring closure to the lives that have been shattered, but this may allow our community to move forward in the path to healing," Paxson added.According to records from Instituto Superior Técnico (I.S.T.), a Portuguese engineering school, a person named Claudio Neves Valente was fired from a monitor position in February of 2000, the same year Loureiro graduated from I.S.T.Witness 'got a good look at the suspect'According to the affidavit filed by the Providence Police Department, investigators received help from a witness identifying the suspected shooter. The witness was a woman who sustained "gunshot wounds" in the attack and "got a good look at the suspect," the court document says. Police interviewing the witness days after the shooting said they showed the woman a photo of Neves Valente and she "quickly froze physically, pushed back, and became emotional." The affidavit says the woman began tearing up and became emotional before confirming he was the shooter. How did the police find the suspect?Police traced Neves Valente based on a car that he rented, according to Perez. Police linked Neves Valente to the vehicle based on surveillance footage and a tip. Investigators traced the car to a rental company in Massachusetts, where they identified the suspect by using the rental agreement and security footage. "That really broke the case open," Rhode Island Attorney General Peter Neronha said. Police traced the car to the site in New Hampshire where he was found dead. According to court documents, Neves Valente rented the vehicle from an Alamo Rent-A-Car and was seen in surveillance footage wearing "the exact same outfit" as he was later seen wearing outside Brown before the shooting.MIT professor's deathEarlier in the week, authorities launched a homicide investigation after Loureiro was found fatally shot in his home in Brookline.Loureiro, who was married and a parent in the Public Schools of Brookline, grew up in a small city in central Portugal and received an undergraduate degree in Lisbon before earning a doctorate in London, according to MIT and Brookline.News. He was a member of the departments of nuclear science and engineering and physics, as well as MIT's Plasma Science and Fusion Center.The FBI initially said investigators did not believe there was a connection between the campus shooting and the MIT professor's murder.Contributing: Jane Mo, USA TODAY; The Providence Journal; Reuters
