What to KnowA shooter dressed in black killed two people and wounded nine others in a classroom at Brown University on Saturday during final exams.A person of interest who was taken into custody on Sunday morning was released later that night after authorities determined the evidence pointed “in a different direction.”Police have since released new surveillance images of a potential suspect, a video timeline and a map showing an area of focus as they ask the public to submit any video footage they might have. Authorities searching for a shooter who attacked students Saturday at Brown University have identified a person of interest in the case, three senior law enforcement officials briefed on the investigation told NBC News on Thursday. Investigators have released several videos from the day of the attack, which left two students dead and nine wounded, showing the person they’re seeking on streets just off campus. The person is wearing a mask or has their head turned in the footage. They have asked for tips from people who might have video of the shooter potentially casing the area the week before. “I believe that this is probably the most intense investigation going on right now in this nation,” Providence’s police chief, Col. Oscar Perez, said at a Wednesday news conference. He said witness accounts of the shooter match the person in the videos. While Brown has 1,200 cameras on campus, the attack was in an older classroom that has “fewer, if any” cameras, Rhode Island Attorney General Peter Neronha said. Investigators believe the shooter used a door that faces a residential street. President Donald Trump accused the Ivy League school of being unprepared. He posted Wednesday on Truth Social: “Why did Brown University have so few Security Cameras? There can be no excuse for that. In the modern age, it just doesn’t get worse!!!” ...read more read less
