Police investigating possible link between Brown University shooting, killing of MIT professor: AP sources

Brown Univ. student on shooting amid search for suspect

Luca Gwathmey, Brown University student, recounts his experience after a shooting on the campus on Saturday. Police are still searching for the suspect days later.

Investigators said they are now looking into the possibility that the Brown University shooting and an MIT professor who was killed in his home may be connected, sources told The Associated Press. 

Two of the people who were familiar with the matter said Thursday that investigators had identified a person of interest in the shootings and were actively seeking that individual.

The backstory:

Two students were killed and nine others wounded after a shooting inside a Brown University classroom on Dec. 13. The gunman is still at large.

Investigators have released several videos from the hours and minutes before and after the shooting that show a person who, according to police, matches witnesses' description of the shooter. In the clips, the person is standing, walking and even running along streets just off campus, but always with a mask on or their head turned.

UPDATE: MIT professor shot, killed in Brookline home

Authorities are investigating the death of a Massachusetts Institute of Technology (MIT) professor after he was found fatally shot inside his Boston-area apartment earlier this week. Sam Mintz with Brookline.News joined LiveNOW's Josh Breslow to discuss the latest on the investigation.

The backstory:

About 50 miles north of Brown University, Boston-area police are investigating the shooting death of a Massachusetts Institute of Technology professor earlier this week. 

Nuno Loureiro was attacked at his home Monday, and no one has been arrested or named as a suspect. The FBI previously said it had no reason to think his killing was linked to the Brown attack.

Loureiro was a professor in the departments of Nuclear Science & Engineering and Physics. He was also the director of MIT’s Plasma Science and Fusion Center.
