Local online sleuthing combined with pervasive surveillance technology helped law enforcement trace the suspect in the Brown University shooting, highlighting both the power and limits of modern investigative tools. Authorities credited a Reddit tip that connected a vehicle to Claudio Neves Valente; investigators also used doorbell cameras, vehicle-tracking feeds and other footage to follow his movements before he was found dead in New Hampshire. The case has reignited debates over campus and municipal public safety: universities and law enforcement are reassessing the role of private surveillance networks, community reporting and open-source intelligence in protecting students while avoiding false leads and privacy oversights.
