A shooter dressed in black killed at least two people and wounded nine others at Brown University on Saturday afternoon during final exams, authorities said, prompting an extensive police search across the Ivy League campus.

University President Christina Paxson said 10 of the shooting victims were students. Another person was injured by fragments from the gunfire. Officers searched academic buildings, backyards and porches late into the night for the suspect, described as a man in dark clothing who may have been wearing a camouflage mask. Security footage showed him leaving the Barus & Holley building, which houses the School of Engineering and physics department, though his face was not visible.

Authorities believe the shooter used a handgun, but investigators have not determined how he entered the exam room, which requires badge access. Rhode Island Gov. Dan McKee said all resources are being deployed to capture the suspect, while Providence Mayor Brett Smiley maintained a shelter-in-place advisory for residents near campus.

Students described harrowing moments of fear and sheltering. Emma Ferraro, a chemical engineering student, ran from the building after hearing gunfire. Others hid under desks or took refuge in nearby businesses. Students were evacuated hours later under police supervision.

Nine victims were hospitalized at Rhode Island Hospital, with one in critical condition and six others receiving intensive care.

The shooting occurred despite Rhode Island’s strict gun laws, including an assault weapon ban passed last spring that restricts sales and manufacturing starting next July but does not prohibit possession. Former “Survivor” contestant Eva Erickson, a doctoral candidate, had left the building minutes before the attack.

President Donald Trump expressed condolences, saying he had been briefed and urged prayers for the victims. Authorities continue to search for the suspect, emphasizing public safety and ongoing investigation efforts.
