Rhode Island officials on Tuesday released new images and video of a person of interest as the search continued for the shooter who killed two Brown University students and injured nine others Saturday. 

Like previously released images, the new enhanced photo shows a man with a black mask, a beanie and what appears to be a two-toned jacket. The shoulders and sleeves appear to be black or blue, while the torso area of the jacket is brown.

A video of the same person walking on the east side of the city before the shooting was also released.

The Providence police chief, Col. Oscar Perez, asked the public to focus on his body movements to see whether there are any distinguishing factors. 

“The way the person moved their arms, the body posture, the way they walk, they carry their weight,” Perez said Tuesday. “I think those are the important movements, patterns, that may help you identify this individual, which is extremely important.” 

Police also asked residents and businesses to search back at least a week for the person. Officials say they learned the person of interest was in the area as early as 10:30 a.m. Saturday, hours before the 4 p.m. campus shooting.

Perez believes the person may have been “casing” the area before the shooting. 

Rhode Island Attorney General Peter Neronha told MS Now before the photos were released Tuesday that officials have been able to use cameras from homes and businesses to establish a “good picture” of the person’s route. 

The FBI, along with Providence and Rhode Island police, released and then quickly deleted a video timeline that they said showed the movements of the person of interest on the day of the shooting. The FBI took the video down because it inadvertently included an address of a person who provided the video. Officials edited and reposted it a short time later.

The video, which appeared to comprise imagery from home security cameras, showed a person walking down brick-lined pathways of a suburban area. Law enforcement officers had been canvassing the area near the shooting knocking on doors, and they have asked the public to reach out with any video or tips. 

Neronha noted that while there are hundreds of cameras around Brown’s campus, the gunman entered a part of the engineering building built in the 1940s or 1950s. 

“There just aren’t a lot of cameras — really very few cameras, if at all — in that part of the building,” Neronha said. “So there may be 800 cameras on the Brown campus, but they’re not located on the edge of the campus, which is where this building is. And unfortunately, in the older part of the building, they’re just not there.” 

Jensine Coggin, a Ph.D. student, was working with an undergraduate student in a lab at the Engineering Research Center at the time of the shooting. She said the research center is connected to the Barus and Holley building, where the shooting took place. 

It’s a hot spot for students who are trying to study, and it gets a lot of foot traffic, Coggin said, adding that many of the students who hunker down there often let their friends in. 

She noted that she didn’t scan in that day either because when she walked in, a door was propped open. 

“They prop doors open; people let people in,” Coggin said. “It could have been anybody, honestly. I mean, Brown, it’s in the middle of the city. … People are always around.” 

Talib Reddick, 22, the student body president, was napping in his dorm after a final Saturday when he awoke to frantic calls from his mom asking for his whereabouts. Reddick said he spent his roughly 12 hours in lockdown keeping in touch with the residents in his dorm and their student government group chat as they waited to learn more. 

Reddick was one of the many Brown students who left early after the school canceled finals, but he noted many were unable to afford the cost of travel changes. 

“A lot of people are afraid and just confused because, of course, we thought that by now the case would have been solved … so it is really upsetting that that’s not the case, and it’s really scary being on campus for those who weren’t able to change their flights,” he said. 

Most of the students he has heard from are happy with how Brown has been responsive to their needs, Reddick said. And while some might be looking for ways it could have been prevented, he has seen the door of the building where the shooting took place propped open “plenty of times.” 

“That’s just how the community is there,” Reddick said. “I mean, Brown has been so safe for us that no one would have imagined that that would be an issue. And the same thing for Providence, Rhode Island — just haven’t faced many situations like this.” 

He said the shooter seemed to have “pretty good knowledge of the school” to have picked the Barus and Holley building.

“To leave out the back way, you’re basically going into the surrounding Providence area, the neighborhoods, a bunch of residential buildings, and it’s much easier to go away unnoticed,” Reddick said.

Authorities have yet to identify a suspect despite days of searching. A person of interest was initially detained early Sunday but was released by the end of the day after officials said evidence pointed in a different direction.

Brown University administrators assured the campus community that they were safe even though the shooter remains at large. A letter from the campus Public Safety Department noted that Providence police are maintaining a perimeter around campus, which has been closed to the public. 

“We have doubled staffing by Brown Department of Public Safety personnel, and we have a significant number of law enforcement and security personnel from multiple other agencies on campus,” the letter said.

Many students have left campus for the rest of the year after the university canceled final exams and classes for the rest of the semester.

Fenan Megerssa, a freshman international student, said his ability to leave campus is limited. He was friends with Mukhammad Aziz Umurzokov, one of the two students killed in the shooting. 

Umurzokov embodied the joy and happiness of what it meant to be at Brown, Megerssa said. But now he feels as though the joy and happiness of being there has been taken away.

“We’re definitely going to come back stronger,” Megerssa said. “But Brown is just not one of those places where you would think this kind of thing will happen.”
