A gunman opened fire at Brown University Saturday afternoon, killing at least two students. Authorities are still looking for the suspect.

Here are the latest developments:

New details about suspected gunman emerge: A man believed to be the suspect, described as wearing dark clothing and estimated to be in his 30s, was seen on video walking down Hope Street, near where the attack took place. Witnesses reported he may have worn a gray camouflage mask, police said.

Residents told to continue to stay inside: A shelter-in-place order remains for residents in and around the Brown University campus. The police will enter some non-residential buildings to escort people to safe locations, said the university in an alert just past 11 p.m.

More law enforcement: There will be enhanced law enforcement presence around town on Sunday, said Providence Mayor Brett Smiley. He also said he “does not recommend” residents cancel their weekend plans while the search for the suspect is ongoing.

Campus classrooms cleared: Officers have searched some of the buildings in the surrounding area of Brown University and cleared the classrooms where students had barricaded themselves to ensure their safety.

Most victims were students: The two people who died in the attack and eight of the injured were students. Nine patients were admitted into Rhode Island Hospital with gun-related injuries.

Building safety to be reviewed: The authorities will debrief at a later stage to look at whether Brown University’s buildings were safe enough after the mayor said the exterior doors of the building where the shooting took place were unlocked at the time.
