The gunman who killed two Brown University students and wounded nine others remained at large late Sunday after authorities announced they were releasing the man detained earlier in the day as a person of interest.

At a hastily called 11 p.m. news conference, Attorney General Peter Neronha said lab tests on evidence linked to the detained man “came back negative,” and that the evidence “now points in a different direction.”

“There is no basis to consider him a person of interest,” Neronha said.

Asked whether the shooter is still in the Providence area, Mayor Brett Smiley said, “We have no way of knowing.”
