BROOKLINE, Mass. — A Massachusetts Institute of Technology (MIT) professor was fatally shot in his Boston-area apartment Monday night.
Police responded to reports of a man shot in his Brookline home. The victim, 47-year-old Nuno F.G. Loureiro, was transported to a local hospital but died from his injuries Tuesday morning, Boston.com reports. Brookline Chief of Police Jennifer Paster said the incident is being investigated as a homicide, and that no suspects had been taken into custody as of Tuesday afternoon.
Louise Cohen, who is Loureiro’s upstairs neighbor, heard multiple gunshots around 8:30 p.m. Monday while in her apartment, The Boston Globe reported. Cohen opened her door and found Loureiro lying on his back inside the apartment building’s entrance and called 911. Brookline Police Deputy Superintendent Paul Campbell said Loureiro was shot multiple times.

Paster said patrol cars and unmarked units will be in the Gibbs Street neighborhood during the investigation.
Loureiro, who joined MIT in 2016, was appointed to lead the school’s Plasma Science and Fusion Center last year. He grew up in Portugal and earned his doctorate in London.
Loureiro is survived by his wife and three children, who range in age from elementary school to college.
FBI: No Known Connection Between MIT Professor Fatal Shooting, Brown University Shooting
The investigation into Loureiro’s death comes as authorities in Providence, R.I., which is approximately 50 miles away from Brookline, continue to search for the gunman who killed two students and injured nine others at Brown University on Saturday.
During a Tuesday evening press conference about the Brown shooting, Ted Docks, special agent in charge of FBI Boston, told reporters there is no known connection between the two crimes, noting Massachusetts State Police Col. Geoffrey Noble reached out to him “very early” in that investigation.
“He made sure that if there is any intelligence, any information in which is connected to what we have here, that they would share that,” said Docks. “At this time, there seems to be no connection as it relates to that particular incident.”
