Well, Steines and an executive producer from ET and The Insider swear up and down that they "Do not pay for interviews". Interesting way she worded it twice exactly that way.
The thing is we won't know the facts about her illness because the only people who know the truth - the nurse, maybe the bodyguard, the friend, and HKS himself are all under the influence of HKS. No independent source of information.
Also earlier heard that the ME mentioned the continued tests of the blood - but did not hear him say also continued tests of her tissues. Isn't it in the tissues that they can trace poisons and/or other hard to find causes of death? Even her hair is a source of information?
If they are only doing further tests on the blood - that is just not encouraging. Maybe he just was not being thorough in saying what is being tested.
I just do not have much faith in this ME.
