P.S.: Quick note on deductive reasoning. Article indicated the Instructor's name & city. Per Wikipedia per 2010 Census, city has 71,551 people. J&T Dive Shop is located in that city & state, has an instructor on staff with that same name, and the website indicates they dive the lake where this took place. So I can't definitively confirm the above info. applies, but I believed the circumstantial evidence sufficient to justify my post. Odds of a medium city in an inland, fairly rural state having more than one scuba instructor with that name seemed low to me, but let's allow for the possibility.
