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.

Police release photo of person seen in 'vicinity' of person of interest

Providence Police on Wednesday released images of a person they say was in the same proximity of the person of interest and are asking for the public to help identify them or for the individual to contact authorities.

The person in those images was "close enough" to the person of interest that officers need to speak with them, Providence, Rhode Island police chief Oscar Perez said during a news conference on Wednesday.

Perez said video footage shows the person was in the "vicinity" of the person of interest.
