• Investigation into links between Brown University shooting and MIT professor's murder ongoing.
• Two Brown students were killed and nine others injured in the mass shooting.
• MIT professor Nuno Loureiro was shot dead at his home two days later.
• A person of interest in both cases has been identified and is being sought.
• Public urged to assist in providing information about the incidents.

Law enforcement is investigating a possible connection between the recent mass shooting at Brown University, which resulted in the deaths of two students and injuries to nine others, and the murder of MIT professor Nuno Loureiro, who was fatally shot in his home in Brookline, Massachusetts, just two days later. Sources close to the investigation believe that the two incidents may be linked, though initial assessments by the FBI had ruled out any connections, according to ABC News and Los Angeles Times.

The shooting at Brown University occurred on December 13, inside a classroom during a final exam review, while Loureiro was shot on December 15 in a residential area. Investigators are actively seeking a person of interest believed to have been in the vicinity of both incidents. There has been persistent frustration among local authorities and residents due to the absence of an arrest almost a week after the Brown shooting, highlighted by statements from Providence Mayor Brett Smiley expressing growing community unease over safety, according to SFGate and Reuters.

During the investigation, police released details about the shooter’s movements captured on surveillance footage, indicating that the suspect escaped on foot and may have been "casing" the area beforehand. Although Brown campus is equipped with numerous security cameras, the attack occurred in an older building with poor surveillance coverage, complicating the manhunt. Investigators' attempts to gather further evidence and visuals have included calls to the public for any footage that might have been recorded prior to and during the incidents, as noted by ABC News and Los Angeles Times.

In the wake of these tragic events, MIT has mourned the loss of professor Loureiro, known for his contributions to clean energy technology and his leadership at the Plasma Science and Fusion Center. The community has expressed deep mourning and a desire for justice, while authorities continue to collaborate on leads regarding the shooting suspect who reportedly is described as being around 5 feet 8 inches tall and stocky, according to SFGate, Reuters, and ABC News.
