As the Rhode Island community mourns, the FBI hopes a new digitally enhanced video will help generate tips from the public that could help them close in on the killer behind the brazen attack at Brown University that left two dead and nine injured over the weekend.

It's unknown if police or federal agents have been able to make headway into the large-scale manhunt across Rhode Island and beyond. The enhanced video offers sharper images of a masked man walking purposefully through Providence neighborhoods, possibly casing the area before the attack, according to police.

That person is more than likely the suspected shooter, not just a person of interest, Providence Police Chief Col. Oscar Perez.

Handout images were provided by the FBI and Providence RIPD of the alleged Brown University shooting suspect.

Also still up in the air is any indication as to the shooter's motive, authorities said in a Tuesday evening news conference. Speculation about what the alleged shooter may have yelled before opening fire — while witnesses disagree if anything at all was said — is a "dangerous road to go down, particularly in today's environment," Attorney General Peter Neronha said.

Neronha said the investigative team has "zero" information about a motive.

The shooting rocked Providence and the community at Brown, one of the oldest and most prestigious universities in the country. A tree and Menorah lighting on Sunday morphed into a solemn candlelight vigil for the victims of the attack. The university is expected to host a virtual interfaith prayer service Wednesday.

The two students who were killed in the mass shooting have been identified as Mukhammad Aziz Umurzokov and Ella Cook, according to the university.

Person of interest likely a suspect in Brown shooting, city police chief says

The suspect in the Brown University shooting is seen in photos released by the FBI.

Providence’s top cop said the person wearing dark clothes seen in video footage shared by the FBI is likely more than just a person of interest in the shooting.

"There’s a lot of leads we have here that show that the person who committed this tragedy is the guy in this video," said Providence Police Chief Col. Oscar Perez.

The chief did not say what other leads point to the person in the video footage.

Witnesses said the person was probably in his 30s, and it was unclear if the person was affiliated with Brown, Perez said.

'Nothing to indicate motive' in Brown shooting, AG says

Rhode Island Attorney General Peter Neronha said there is "nothing to indicate motive at all related to ethnicity or political outlook."

"That is a dangerous road to go down," said the attorney general, adding that while one or two witnesses heard the shooter "shout something," others did not.

Neronha was speaking at a news conference on Tuesday evening. At about the same time, Brown put out a statement dispelling rumors about a potential suspect, urging people not to target individuals. The university removed a webpage featuring a community member and said there was "harmful doxxing activity."

Brown confirms identities of 2 students killed: 'Brilliant and beloved'

Brown University President Christina Paxson on Tuesday confirmed the identities of the two students who were shot and killed on campus over the weekend, remarking that they were both near the start of their college careers.

Ella Cook was a sophomore and Mukhammad Aziz Umurzokov was in his very first semester, Paxson said. Cook was an "accomplished competitive pianist," vice president of the school's Republican Club, member of the Alpha Chi Omega sorority and a volunteer at her home church in Alabama, Paxson said. Umurzokov planned to concentrate in biochemistry and molecular biology on his way to becoming a neurosurgeon, and in high school in Virginia served as president of his Model United Nations chapter and Scholastic Bowl team captain, Paxson said.

"Both were brilliant and beloved — as members of our campus community, but even more by their friends and families. Our hearts continue to be with them in their profound sorrow," Paxson said.
