Brown University officials are asking anyone who was in the Barus and Holley Hall - the site of Saturday’s shooting - to assist investigators in their efforts to track down the suspect.

“We ask that anyone who was in Barus & Holley building on Friday or Saturday, Dec. 12-13, immediately contact the Providence police to arrange for an interview,” the university said in an update Monday evening. “Even what seems like an incidental detail may ultimately be helpful in law enforcement’s efforts to protect our community.”

The university also emphasized that campus safety remains its foremost priority. It said reports circulating about additional intruders and violence on and around campus were unfounded and that police have responded to several calls about reported threats, each determined to be baseless. Brown has also experienced an uptick of “swatting” calls, it said.

The university said it has put in place additional safety measures, including an enhanced security presence on campus and restricted building access.
