Follow live updates as police seek to identify masked person as manhunt enters fourth day for Brown University shooting

After determining that a man they had detained was not the killer, Rhode Island officials have searched for more evidence and released photos of a possible gunman.

The shooting on Saturday left two students dead and nine wounded. Police are looking for a person of interest wanted in connection with the attack.

Like previous images, the enhanced photo showed a man with a black mask, a beanie and what appears to be a two-toned jacket.

Authorities are asking the public for any footage they might have of the gunman who fatally shot two students and wounded nine others at Brown University.

The Brown University building where two students were killed had no surveillance cameras, even as the school president’s home is equipped with security monitoring.
