By Andrea Margolis, Julia Bonavita, Fox News, December 17, 2025:

BROOKLINE, Mass. – Authorities are investigating the death of a Massachusetts Institute of Technology professor after he was found fatally shot inside his Boston-area apartment earlier this week.

Nuno F.G. Loureiro, 47, died at a hospital on Tuesday morning after being shot on Monday night inside his apartment in Brookline, Massachusetts, the Norfolk District Attorney’s Office said in a statement.

Officers with the Brookline Police Department arrived at the three-story apartment building after receiving reports of a man shot at his home, prosecutors said. Loureiro was pronounced dead Tuesday morning.

Shooting rocks Boston suburb
The shooting took place in Brookline, an affluent suburb a few miles outside of Boston. It is being investigated as a homicide, and no suspects have been taken into custody.

The Brookline Police Department and Norfolk County District Attorney’s Office are investigating Loureiro’s death, the Massachusetts State Police said in a statement to Fox News Digital.

“This remains an active and ongoing homicide investigation,” Brookline Chief of Police Jennifer Paster said in a social media post. “In order to protect the integrity of the investigation, we are limited in the information we can share at this time and ask for the community’s understanding and patience. While we investigate this incident, we will have dedicated patrol cars, officers, and unmarked units in the Gibbs Street neighborhood.”

The Brookline Police Department did not immediately respond to Fox News Digital’s request for comment.

Louise Cohen, who is Loureiro’s upstairs neighbor, was lighting a menorah candle on Monday at around 8:30 p.m. when she heard multiple gunshots, The Boston Globe reported.

Upon opening her door, Cohen reportedly witnessed Loureiro lying on his back inside the apartment building’s entrance and called 911, along with another neighbor and Loureiro’s wife.

“I can’t sleep now,” Cohen said, according to the Globe. “This family is so amazing. I can’t imagine anyone wanting to kill him.”

Questions about Brown University shooting

Loureiro’s death comes as authorities in Providence, Rhode Island – located about 50 miles away – are still searching for the gunman who killed two Brown University students and injured nine others during a class study session on Saturday.

However, Ted Docks, special agent in charge of FBI Boston, told reporters on Tuesday that, “It seems that there’s no connection,” between the two crimes.

The FBI did not immediately respond to Fox News Digital’s request for comment.

Professor makes mark at MIT

Loureiro joined MIT in 2016 and was appointed to lead the school’s Plasma Science and Fusion Center last year, when he aimed to research and expand clean energy technology, according to The Associated Press. The center stands as one of the school’s largest laboratories and had over 250 researchers, staff members and students when Loureiro was selected as its leader, the school’s website stated.
