Authorities extended the search for a suspect in the Brown University shooting into a fifth day while working forensic leads, including DNA evidence, and seeking a second man who may have crossed paths with the possible shooter. Brown’s administration confirmed the suspected gunman had no current affiliation with the university, but the investigation triggered a wave of online accusations and harassment targeting a pro‑Palestinian student who had no proven link to the attack. Campus‑safety experts and university officials are now wrestling with two immediate tasks: cooperate fully with law enforcement on the manhunt and step up protections for students subjected to false online accusations. University communications offices must rapidly counter misinformation and support victims of harassment while preserving law‑enforcement confidentiality. Colleges across the sector should review rapid‑response procedures for campus violence and misinformation, ensure counseling and legal resources for targeted students, and coordinate with local police on information flows to prevent misidentification and online vigilantism.
