Law enforcement has yet to apprehend the suspect in the Brown University shooting on Saturday that killed two students and wounded nine others.
Officials on Monday held a press conference stating they are working a multi-agency case and doing everything they can to identify and arrest the suspect.
The FBI also announced a reward of up to $50,000 for information leading to the identification, arrest, and conviction of the individual responsible for the shooting.
Authorities on Monday also released several new videos of the suspect walking on a neighborhood sidewalk, but they are low quality and none offer a clear view of his face.
