“I reached out and tried to grab him but since the current was so strong it took him away from my hand,” said the teen. “He was going under, coming up gasping for air…and he went around the corner and I lost sight of him.”

Crews searched for the other teen, a 17-year-old boy, all day Wednesday until calling off the search around 9 p.m.
