A member of Porter’s group called 911 when they couldn’t get him out, but it was too late, authorities said. Zachary Porter, 20, of Lake Bluff, Illinois, was submerged Sunday evening as the tide came in, and his body was recovered Monday morning, Alaska State Troopers spokesperson Austin McDaniel told The Associated Press.
