I read old affidavits submitted to Greer at the time that the Schindlers petitioned Greer for Michael's removal as her guardian. Iyer was one; Trudy somebody; and a third one. Greer ignored these and refused to remove Michael as her guardian. I think two of these are two more nurses than the 3 from long ago. I can't tell you where to look because I followed a link on a Terri thread on here. Try googling in nurses/affidavits and look for older dates as I don't remember any names except Carla Iyer and this is at least her 2nd affidavit.
