Tension mixes with grief and frustration at Brown University in Rhode Island as police search for suspect

What we know so far about the attack in Providence, Rhode Island

Tension mixed with grief and frustration in Providence on Monday around the Brown University campus, after authorities said they were still searching for a suspect who killed two students.

Nine additional students were injured in Saturday’s shooting on the Ivy League campus in Rhode Island, which is woven into the heart of the city’s East Side neighborhood, a community that to many feels more like a small town than the capital city of the smallest state in the US.

The sound of a helicopter hovering overhead mixed with sirens throughout the day as federal and local law enforcement officers could be seen canvassing businesses to ask for the location of cameras and sweeping properties in the neighborhood with a dog.
