Authorities Investigating Connections Between MIT Professor Killing And Brown University Shooting

BROOKLINE, MA — The search for a suspect in the Monday night shooting death of MIT professor Nuno Loureiro continues Thursday in both Brookline and Cambridge.

As of Thursday, authorities were investigating potential connections between the professor's killing and the shooting at Brown University that killed two students and critically injured 9, according to multiple sources, including the New York Post and WPRI Target 12. Earlier in the week, the FBI said it knew of no connection between the crimes.

While no arrests have been made in either case, police have released images of two persons of interest in the Brown University shooting. The second person, whose photo was released on Wednesday, was described as being "in proximity to" the first person at the time of the incident.

The manhunt for Loureiro's killer is a combined effort by Massachusetts State Police assigned to the Norfolk District Attorney’s Office, Brookline Police Officers, and MIT Police. The university announced key card access will be required for all buildings at least through this coming weekend.

Loureiro, 47, was found suffering from gunshot wounds after police responded to his apartment at 9 Gibbs St. at approximately 8:30 p.m.

After hearing what sounded like numerous shots, Loureiro’s neighbor Louise Cohen reportedly opened her door and found the professor lying on his back in the building’s shared foyer with multiple gunshot wounds. She, along with others, called 911 immediately.

Loureiro was rushed to Beth Israel Hospital in Boston, where he later died from his injuries on Tuesday morning. The Portugal native was a decorated professor of nuclear science and engineering. In 2024, he became the director of Plasma Science and Fusion Center Director, one of the university’s largest and most prominent labs.

Loureiro is survived by his wife, Ines, and their three children. His family was reportedly home at the time of his killing. Police have increased their presence in the neighborhood of his home and on MIT's campus for search and safety reasons.
