• Authorities still hunting for the perpetrator of the deadly mass shooting at Brown University are pursuing a new lead based on photos and videos of a person taken around 2 p.m. Saturday, hours before the attack. The suspect is “approximately 5’8” with a stocky build,” said the FBI, which announced a $50,000 reward leading to an arrest and conviction. • A person of interest detained earlier in connection with the attack has been cleared, but the early focus on that person may have delayed the investigation by up to a day, a CNN security analyst said. • The shooting left two students dead and nine others injured at the Ivy League school in Providence, where classes and exams have been canceled. The campus remains on edge, and the governor has ordered a sweeping review of school safety measures. At least 75 school shootings have unfolded this year in the United States. Authorities in Providence, Rhode Island, released new video of a possible suspect seen walking through neighborhoods in the hours leading up to the deadly attack at Brown University, leading some to ask what the person was doing for two hours prior to the shooting. “Based on my experience, I think that maybe he was waiting for either a certain person or certain conditions there to initiate this attack,” former FBI agent Scott Curtis told CNN’s Wolf Blitzer. “I would question of whether he knew somebody personally that he thought was going to be in that location at that time, and he was waiting for that time that he thought that that person would arrive to initiate this attack.” In these hours before the assault, the subject put themselves at risk by hanging around for so long – to the point where someone might have thought they looked suspicious, Curtis said, and those hours also expand the pool of people that may have run into them before the attack.
