In Rhode Island, the search for a gunman who killed two students and injured nine others at Brown University on Saturday has entered its third day, after authorities released a “person of interest” detained early Sunday. Seven of the students remain hospitalized in critical condition. A shelter-in-place order around the Brown campus was lifted early Sunday morning; meanwhile, the university has canceled all classes for the rest of the semester. According to the Gun Violence Archive, Saturday’s attack was the 389th mass shooting in the U.S. this year. There have since been three other mass shootings. We’ll hear from one of the survivors, Mia Tretta, later in the broadcast.
