Search For Brown University Shooter Resumes

Authorities are again searching for the person seen in grainy video walking away from the Brown University shooting that killed two students and injured nine. Officials said late Sunday that they released a person of interest they had detained earlier in the day, finding no reason to keep him in custody. This setback left law enforcement without a known suspect. The shooting happened Saturday during a busy time on campus, causing chaos and a lockdown. The gunman fired more than 40 rounds inside a classroom. The victims included a sophomore who was vice president of the Brown College Republicans and a freshman whose family immigrated to the U.S. from Uzbekistan.
