Police have issued an arrest warrant for the suspect in a mass shooting at Brown University that killed two people and injured nine others, sources close to the investigation revealed. Authorities are actively searching for the individual and a vehicle believed to have been rented by the suspect.

There is an exploration of a possible link between the shooting at Brown and the murder of a professor at the Massachusetts Institute of Technology (MIT) just two days later.

This investigation has entered its sixth day, with detectives canvassing the area, seeking information from the public, and requesting home-security video footage.

A planned news conference in Providence was unexpectedly canceled, although police indicated that updates would follow shortly.

Authorities confirmed they are reviewing possible connections between the Brown University shooting and the killing of Nuno F Gomes Loureiro, a 47-year-old MIT professor, who was fatally shot multiple times at his home in Brookline, Massachusetts, located approximately 50 miles from Providence.

Police are working with evidence suggesting a rental car seen at both crime scenes may be linked to the same suspect.

Earlier, federal agencies had reported no known connection between the two incidents, but the current focus has shifted following new evidence. On Wednesday, police released an image of a person who is believed to have been near their primary suspect.

Providence Police Chief Oscar Perez expressed the urgency of the situation, stating, We don't know where the person is or who he is. Additionally, a previously circulated video showed an individual wearing a black mask in the vicinity of the university, which is being scrutinized for any potential leads.

Community responses have been marked by frustration over the investigation's apparent slow progress. In reassurance, Rhode Island Attorney General Peter Neronha expressed confidence that the perpetrator will be apprehended soon. The FBI has also put a $50,000 reward on the table for information leading to the identification, arrest, and conviction of the shooter.

The shooting incident unfolded at Brown University's Barus & Holley engineering building during crucial final exam periods, leading to a tragic and devastating impact on the university community. The victims have been identified as Ella Cook from Alabama and Mukhammad Aziz Umurzokov, a freshman student of Uzbek descent.
