Police in Rhode Island say they have a person of interest in custody after a shooting at Brown University killed two students and wounded nine others. The incident happened Saturday afternoon in a classroom during final exams. The shooting paralyzed the campus, with students sheltering in place for hours. Nine students with gunshot wounds were taken to the hospital, with one in critical condition. Authorities believe the shooter used a handgun.  An FBI agent says the arrest took place at a hotel in Coventry, about 20 miles from Providence.
