MINNEAPOLIS (WCCO) — Thunder Wambade Brothersofall, 16, was last seen on Sept. 15 around 5:30 p.m. while swimming with friends in the Redwood River, Redwood Falls police say. A search crew will remain in Ramsey Park around-the-clock until Thursday, when a third ground and air search is set to begin.

Police discourage the public from searching in the river as water levels are high and the currents are fast and erratic.
