Authorities are facing increasing pressure to apprehend an ‘organized’ suspect who remains at large after a tragic attack at Brown University that left two people dead and nine others injured.

The law enforcement response has come under heavy criticism following Saturday’s shooting, particularly after a ‘person of interest’ was mistakenly released, having been incorrectly identified as the shooter.

Initially, police announced they had a suspect in custody, only to later retract that statement. They also issued conflicting reports about a second shooting, which turned out to be baseless.

In an effort to generate new leads, authorities released surveillance footage on Monday. The video depicts the suspect calmly walking through the Providence, Rhode Island area shortly after the attack.

Revealing the footage seemed to underscore the lack of solid leads, with university officials urging witnesses to come forward with any information, no matter how minor, that might help identify the gunman.

The gunman opened fire on a weekend study session classroom on the seventh floor of Brown University’s engineering building on Saturday afternoon, and officials said he walked into the building because it was left unlocked for midterm exams. 

Criminal profiler John Kelly told Fox News that this security lapse allowed Brown University campus to be a ‘soft target’ for the ‘organized’ killer. 

In an updated description from the FBI, the suspect is described as standing 5’8″, with ‘stocky build’, wearing a black mask, dark jacket, black beanie, gloves and boots. 

Investigators have come under scrutiny in the days after the shooting, as footage and images of the gunman have failed to offer a look at the suspect’s face or specific information to track them down. 

Authorities are under mounting pressure to track down the at-large suspect who killed two people and injured nine more at Brown University on Saturday 

A $50,000 reward has been issued for information leading to the suspect’s arrest, with authorities on Monday releasing new surveillance footage of the killer walking the Providence, Rhode Island community after opening fire

Kelly cited unlocked doors, an apparent knowledge of the layout of the engineering building and its surveillance cameras as evidence that the killer meticulously planned the attack ahead of time. 

‘College was a soft target – doors open and no security,’ said Kelly, a criminal profiler and the president of STALK Inc. 

‘The killer was familiar with the area, enraged, probably at the college or engineering program. Organized,’ he told Fox news. 

‘Dressed for the occasion – and very comfortable with a semiautomatic.’ 

In the latest footage, the suspect was seen walking slowly along a street in the aftermath of the attack that killed two people. 

The gunman was seen walking with his hands behind his back, at one point stopping to turn around and look across a road and over a fence with no apparent urgency.  

With the suspect remaining at-large into Tuesday, Kelly said the task for investigators to track down the gunman grows increasingly difficult the longer the manhunt continues. 

‘They don’t know if he’s 500 miles away or five doors down the street,’ he said. 

‘What they do know is he’s a psycho killer and mass shooter. If they don’t get him, there is a lot of fear for people living there, and there will be a lot of scared kids returning to campus.’

FBI Director Kash Patel has been at the center of criticisms of the investigation, as he was accused of repeating a pattern throughout the year of premature announcements of suspects. 

On Sunday, Patel bragged about how the FBI had used its advanced cell phone tracking technology to detain a suspect at a hotel in Rhode Island, and the suspect’s name was leaked to the press. 

But just hours later, it was announced that the ‘person of interest’ would be freed. 

Investigative experts warn that authorities must now start from scratch, reviewing all the evidence again after they were led to the wrong individual. 

On Monday, university officials pleaded for any information from witnesses that could help lead to the suspect, saying in a statement that ‘even an incidental detail may be helpful’ as they scramble for answers.  

It comes as the two victims who lost their lives in the horror attack have been identified as neuroscience student Mukhammad Aziz Umurzokov, 18, and sophomore Ella Cook, 19. 

Umurzokov’s roommate Khimari Manns paid tribute to the American-Uzbek student as kind, intelligent, and ‘always there for you’. 

‘(He was) just a ball of joy, ball of energy,’ Manns told CBS affiliate WPRI.

‘He raises everybody else to a certain level. He made sure I had my stuff done. He made sure he had his stuff done. He was just always there… He was kind.’

Cook was the vice president of Brown University’s Republican Club, and was remembered by Rev. Craig Smalley at a memorial as ‘incredible, grounded, faithful bright light.’ 

‘She encouraged and lifted up those around her,’ Smalley said. 

Cook also held a leadership role at Brown as vice president of the university’s Republican club, a position confirmed by fellow students and alumni.

Former Brown student Alex Shieh, who said he knew Cook, wrote on X that she was widely respected across ideological lines on campus.

‘Everyone at Brown who knew Ella, regardless of their politics, found her to be friendly and kind,’ Shieh wrote. ‘My thoughts are with Ella’s family. Ella was a promising young leader taken too soon.

‘I knew Ella through Brown Republicans, where she was vice president. Being a conservative at Brown isn’t always the easiest, but Ella was never afraid to share her beliefs on an overwhelmingly liberal campus and support others in doing so.’ 

Despite over 400 law enforcement agents deployed to assist the manhunt, authorities have been criticized for a lack of movement in tracking down the suspect

The bungled investigation has been slammed by many on social media as the suspect remains at large. 

In the chaotic aftermath of the shooting, officials announced that they had arrested a suspect, only to walk back that announcement less than an hour later. 

Conflicting reports from the chaotic scene also claimed a secondary shooting occurred blocks away from the campus around an hour after the initial shooting. Brown University said in an update that those reports were ‘unfounded.’ 

Law enforcement sources told CNN that the confusion over reports of a second shooting were sparked by a ‘confrontation’ with an individual blocks away from the campus, which resulted in gunfire.

The police source said that the connection between the incident and the suspected shooter is uncertain, but the incident was the reason for conflicting reports that a suspect was in custody.
