Marcus L. Martin felt instant trepidation when he saw five adults wading thigh- and waist-deep in the Scioto River last weekend. The Baptist pastor is a frequent boater on that area of the central Ohio waterway north of Columbus. He knew the area where the group was standing Sunday to be treacherous due to a steep drop-off. He took a photo of the group when he returned past them. It may be the last portrait of a group of friends who drowned that day, two Honduran married couples and their friend. Authorities have not yet confirmed the individuals pictured in the pastor's photo.
