The FBI released a new video timeline Tuesday afternoon of a person of interest in the Brown University shooting and offered a $50,000 reward. The shooting left two students dead and nine others injured at the Ivy League school in Providence, Rhode Island, 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.
