By the principles of what makes a witness credible, she was clearly the most credible witness of any. She had nothing to gain, and much to risk by coming forward with the truth. She backed up her claims contemporaneously by reporting Michael to the police over the suspected insulin injections. Her testimony is corroborated on many points by other nurses who worked with Terri. Mrs. Iyer has never budged one inch on any of it. She will tell you the story again today in every detail.
All the nurses (and others) confirmed that Michael was giving the orders. Some say he tampered with the charts. One of the facilities got a restraining order and had Michael thrown out for threatening the staff.
I'll leave the legal part to someone who knows more than I do, but from a medical viewpoint, she isn't very credible when she claims that Terri Schiavo was "alert and oriented." That means something very specific medically. It means that someone has given you name, place, and date. Yet she then describes
Terri spoke on a regular basis while in my presence, saying such things as “mommy,” and “help me.” “Help me” was, in fact, one of her most frequent utterances. I heard her say it hundreds of times. Terri would try to say the word “pain” when she was in discomfort, but it came out more like “pay.” She didn’t say the “n” sound very well. During her menses she would indicate her discomfort by saying “pay” and moving her arms toward her lower abdominal area.Carla Iyer's description of those few simple words doesn't square with Terri Schiavo then saying "Terri Schiavo, convalescent center (I'd accept "hospital"), June 13th 1995."
