Search for Brown University shooter enters fourth day as FBI releases photos of suspect

Authorities still hunting for the perpetrator of the deadly mass shooting at Brown University are pursuing a new lead based on photos and videos of a person taken around 2 p.m. Saturday, hours before the attack. The suspect is “approximately 5’8” with a stocky build,” said the FBI, which announced a $50,000 reward leading to an arrest and conviction.

A person of interest detained earlier in connection with the attack has been cleared, but the early focus on that person may have delayed the investigation by up to a day, a CNN security analyst said.

• The shooting left two students dead and nine others injured at the Ivy League school in Providence, where classes and exams have been canceled. The campus remains on edge, and the governor has ordered a sweeping review of school safety measures. At least 75 school shootings have unfolded this year in the United States.
