Hmm.
I agree with those posters pointing out that if anyone who had met her had anything remotely significant to divulge in the context of her conviction, which is so unsafe it beggars belief, it would have been all over the press in a heartbeat after the trial.
The main fascination with her is that there is no psychological evidence against her, and if you believe the official narrative she just woke up one morning and decided to trash her career by abusing her trusted position as a nurse by carrying out acts that have not been reliably proven as methods of murder. And that of course plays into our fears that anyone, no matter how "lovely" / innocuous could be plotting harm. It really is witch hunt territory.
And for someone accused of a heinous crime or action, it's not until you go through the system, which you may have trusted, you realise how quickly it runs over you even if you are innocent.
Our justice system is adversarial, and not really about getting to the truth. It's a case of which side can "win". People don't want to believe that.
But just imagine if you were accused of a crime. You know you are innocent. You can't "prove" it, but there is circumstantial evidence being used that you can't debunk - your phone pinged in the area, you have been at the crime scene, you didn't get on with the victim.... it is presented as compelling. Your freedom and ability to live your life as you choose is on the line. Your denials are rejected. You are told you are guilty, over and over again. Your friends and family are interviewed. They don't "believe" you are guilty, but can't prove you aren't to the satisfaction of the police because they weren't there.
Your legal advice is that you can risk trial, but if you have pleaded not guilty and lose, your sentence and treatment will be far harsher. Admitting guilt garners a softer ride.
Psychologically you become paranoid, neurotic. If you are "too calm" you are guilty. If you become defensive or aggressive then it feeds the idea that you are capable of the act. You are just rolled around the system like it's a pin ball machine. Everyone involved in your case on an official level believes you are guilty.
It's a pretty horrific experience.
