James Arthur Ray, right, and one of his defense attorneys Truc Do, listen to testimony of Ted Mercer, during the criminal trial of Ray, Thursday, April 7, 2011, in Camp Verde, Ariz. Ray faces three counts of manslaughter, where Ray led the sweat lodge ceremony at a retreat near Sedona, Ariz. A defense attorney for a self-help author charged with manslaughter began his cross examination Thursday of Mercer who helped out at the author’s sweat lodge ceremony. Mercer was tending to the fire used to heat hot rocks for the events from 2007 to 2009. Mercer says Ray’s October 2009 ceremony was hotter than the two previous ones, but Mercer acknowledged in questioning from defense attorney Luis Li that there’s no way he could actually gauge the temperature inside the structure.
