On Saturday, law enforcement released a video of an individual dressed in black and walking on a sidewalk near the scene of the shooting. The individual in the video remains a person of interest, Police Chief Oscar Perez said, but officials will continue to look for additional video evidence and canvas the surrounding neighborhood for more footage.

Police are searching for a gunman who shot dead two students and injured nine others at Brown University in Providence, Rhode Island.

President Donald Trump called the shooting “a terrible thing,” saying, “All we can do right now is pray for the victims.”
