Water searches were postponed late on Sunday for a 17 year old South Bend boy last seen Saturday night offshore in the area of Washington Park. The search for Rahem Mason was postponed until conditions improve on Lake Michigan, according to the Indiana Department of Natural Resources. The search for Mason began shortly after he was seen going under the water around 7pm on Saturday, the DNR said. The condition of the lake will be evaluated on a daily basis to continue the search.
