You are making things up Wyatt or you are being deceptive, it did not get into the 80s until close to 11AM.  Think how silly the statement is:  Every detail said "heat-related problems" about the temps at 9:30AM, in the 70s.  You are mixing up facts Wyatt.  It was around noon that things started to get a little warmer into the 80s.  Did you even wonder why all of the reports gave temperatures after 11:30 when she left at 9:30.
