Authorities are investigating a potential connection between a mass shooting that occurred last weekend at Brown University and an attack near Boston that resulted in the death of a professor from the Massachusetts Institute of Technology (MIT). This information comes from three sources familiar with the ongoing investigation, who spoke on the condition of anonymity. Investigators have identified a person of interest and are actively searching for this individual. During the shooting at Brown University, the attacker killed two students and injured nine others in a classroom located in the engineering building before fleeing the scene. In a related incident, MIT professor Nuno F.G. Loureiro was shot in his home in Brookline, a Boston suburb, on Monday night. The 47-year-old physicist succumbed to his injuries the following day at a local hospital. Although the FBI previously stated there were no known links between the two cases, the investigation remains ongoing. It has been almost a week since the shooting at Brown University, and authorities are under pressure to make an arrest. The lack of clear images of the suspect has heightened frustration among the public. Investigators are asking the community to review any surveillance footage from the week leading up to the attack, as they believe the shooter may have scouted the area beforehand. They have released several videos showing a person who matches the description provided by witnesses, though the individual remains masked or turned away from the camera. Despite having approximately 1,200 security cameras on campus, the incident occurred in an older section of the engineering building with limited surveillance coverage. Officials believe the shooter may have entered and exited through a door facing a residential street, which may explain the lack of captured footage. Providence Mayor Brett Smiley has reassured residents that the city is taking all necessary precautions to ensure safety. He acknowledged that families may be concerned about staying in town during the upcoming holidays. As the investigation progresses, authorities continue to gather evidence and search for the suspect, who is described as approximately 5 feet, 8 inches tall and stocky. The motives behind the attack remain unclear, and there is currently no evidence suggesting a specific target. Nuno Loureiro, a respected professor who joined MIT in 2016, was leading the Plasma Science and Fusion Center, focusing on clean energy technology. He was known for his mentorship and leadership within the institution, and his contributions to the field will be greatly missed.
