The Search Intensifies with New Evidence
Providence Police and the FBI released enhanced surveillance footage on December 16, marking their most aggressive push yet to identify the Brown University shooter. The clearer images and videos represent the sharpest visual evidence available since the gunman opened fire in the Barus & Holley engineering building three days earlier. Police Chief Oscar Perez described the footage as “the clearest picture we have of the individual we believe to be responsible.”
The enhanced footage emerged after initial security camera releases failed to generate solid leads. Authorities deployed advanced video enhancement techniques to sharpen image quality and stabilize movement patterns captured by campus surveillance systems. The FBI’s involvement signals the federal government’s commitment to solving what has become a high-profile manhunt stretching across state lines.
A Deadly Attack During Finals Week
The shooting unfolded at 4:05 p.m. on December 13 in Room 166, a 186-seat first-floor lecture hall where students attended an economics exam review session. The gunman entered the unlocked building through an unknown access point and fired multiple rounds with a 9mm handgun before fleeing through the Hope Street exit. Among the dead were Ella Cook, vice president of Brown College Republicans, and Mukhammad Aziz Umurzokov, a recent immigrant from Uzbekistan.
Brown University’s emergency response included immediate campus-wide alerts, though communication missteps occurred when officials prematurely reported a suspect in custody, only to retract the statement twenty minutes later. The mistake highlighted the challenges of managing real-time crisis communications while coordinating between multiple law enforcement agencies. Over 400 officers from Providence Police, Rhode Island State Police, FBI, and ATF mobilized for the manhunt.
Investigation Faces Weather and Evidence Challenges
Overnight snowfall on December 13-14 hampered evidence collection efforts, particularly fingerprint recovery and trace evidence gathering around the campus perimeter. Investigators confirmed the shooter used a 9mm handgun based on ballistics evidence recovered from the scene, but no shell casings or other physical evidence has led to identification. The FBI conducted raids on a Coventry hotel and searched locations out-of-state, but all detained individuals were subsequently cleared of suspicion.
The investigation spans multiple jurisdictions as authorities work to trace the suspect’s movements before and after the shooting. Providence Police specifically requested residents submit doorbell camera footage and other surveillance material from December 13 afternoon. Attorney General Peter Neronha emphasized that previous detentions yielded no valid persons of interest, underscoring the investigation’s lack of concrete leads despite extensive resources.
Campus Security Questions Mount
The attack occurred during the second day of Fall 2025 final examinations, when academic buildings typically see heavy student traffic and extended hours. The Barus & Holley building houses both engineering and physics departments, making it a central campus facility with significant foot traffic. Brown University cancelled all remaining classes and exams for the fall term, disrupting academic schedules for thousands of students during the critical finals period.
The shooter’s ability to enter an unlocked academic building and flee undetected raises questions about campus security protocols at elite universities. Unlike many recent campus shootings where perpetrators were quickly identified through existing databases or campus connections, this case presents law enforcement with an unknown assailant who appears to have avoided detection systems. The extended manhunt suggests either sophisticated planning or significant gaps in campus security infrastructure that investigators are now working to address.
