Police Investigating Potential Connection Between Brown University, MIT Shootings

Police are investigating a potential connection between the Saturday shooting at Brown University and the Monday killing of an MIT professor in his home, based on information that has emerged in the last 24 hours.

Multiple people familiar with the investigation told several outlets that federal, state, and local authorities are now examining evidence that the two crimes, which took place less than 50 miles apart, may be linked, marking a significant shift in both stalled investigations.

The violence began Saturday afternoon when an unidentified gunman killed two Brown University students — Ella Cook and Mukhammad Aziz Umurzokov — and injured nine others after opening fire inside Brown’s Barus & Holley engineering building.

48 hours later, an assailant shot MIT professor Nuno Loureiro multiple times inside his Brookline, Massachusetts, home.

Authorities have yet to identify suspects in either case, and initially stated in a Tuesday press briefing that there “seems to be no connection” between the two shootings.

Providence police and the FBI have steadily released images and video depicting two persons of interest walking the streets around Brown University before and after the shooting, asking the public for any information to identify them.

Surveillance footage from Brown University captured the alleged shooting suspect — wearing a dark jacket, mask, and hat — walking around campus for hours before the attack around 4 p.m. Saturday. Multiple law enforcement agencies have expanded their search for video evidence, releasing a new map that widens the area of interest around the university.
