A Reddit post helped find MIT and Brown shooting suspect. Here's what we know

"A Reddit post by an observant witness helped lead investigators to the gunman officials say was responsible for the killing of two students during the shooting at Brown University on Saturday and for the fatal shooting of an MIT physics professor two days later. That's according to an affidavit from the Providence Police Department. Brown students Ella Cook, 19, and Mukhammad Aziz Umurzokov, 18, were killed and nine were injured in the attack on Saturday at the school."

"MIT physics professor Nuno F.G. Loureiro was killed at his home in Brookline, Massachusetts, about 50 miles away from the site of the mass shooting in Providence, on Monday. Earlier this week, law enforcement tracked Valente to a Salem, New Hampshire, storage unit where he was discovered dead. "While we'll never be able to prosecute this individual, I hope this result begins to provide some small measure of closure for the victims and their families," said Rhode Island Attorney General Peter Neronha."

"Police say Claudio Manuel Neves Valente, 48, is the man responsible for the two attacks in New England. He was born in Torres Novas, Santarem, Portugal and was a legal permanent resident of the United States. Valente arrived in the country in August 2000 as a graduate student at Brown under an F-1 visa, which is reserved for international students to attend colleges or universities full-time in the U.S. Leah Foley, the U.S. attorney for the District of Massachusetts, said at a news conference on Thursday that Valente and Loureiro, the slain MIT professor, attended the same academic program between 1995 and 2000 at a university in Portugal. Valente was enrolled in Brown's PhD physics program from fall 2000 until the spring 2001 semester, after which he took a leave of absence. He officially withdrew in the fall of 2003, according to the affidavit."

Investigators linked a Reddit tip to the identification of a suspect in two separate shootings in New England that killed three people and injured nine. Two Brown students, Ella Cook and Mukhammad Aziz Umurzokov, were killed in a shooting on campus, and MIT physics professor Nuno F.G. Loureiro was fatally shot at his Brookline home two days later. Law enforcement tracked the suspect, Claudio Manuel Neves Valente, to a Salem, New Hampshire, storage unit where he was found dead. Valente had past ties to Brown, entered the U.S. as a graduate student in 2000, and later withdrew from the PhD program.
