I strongly doubt it was a suicide. The Australian police force were on the side of her killers, so they called it a "suicide" because they didn't want to investigate her murder.
She was AUSTRIAN. You are accusing an entire police force in Austria of being complicit in a murder. Can you take a moment to think about that?
They did not give her adequate protection, true... and you are entitled to have your suspicions, but are you aware that in the US and Canada (I am presuming that is where you may be from...) stalkers continue to stalk even with anti stalking laws and restraining orders? In the US, it also depends what state you live in. Women, especially women of colour, are vulnerable no matter what their profession. On a regular basis 1 in 10 women are stalked, virtually all have experienced sexual harrassment,1 in 6 are sexually assaulted although that number is likely way higher as it is underreported. https://www.womenslaw.org/about-abuse/forms-abuse/stalkingcyberstalking
While it is true, someone may have made it look like a suicide (writing 3 suicide notes is a bit much, but in them she surely must have included info that only her family and friends knew. She lost her business to antivax pieces of absolute SHIT who stalked and threatened her and her clients. That prolonged harrassment is certain to give anyone PTSD... and losing her business is likely what put her over the edge. Health professionals in general and worldwide are under attack and that should be for the moment what we focus on and should assure ends before no one wants to take on the profession. I wrote more here in the previous post about the doctor.
I've read a news article about the incident, and there was no mention of the doctor leaving behind any notes. Based on what I had read, it seemed suspicious.
In the USA, it's now public knowledge that some police officers carry extra guns known as "drop guns" that they can plant on the bodies of people they kill so that they can plausibly claim self defense. (I'm not saying it happens every day, but it is a "thing".) If cops can falsely claim self defense, it stands to reason that they might also falsely claim suicide.
There is a lot of justifiable suspicion about the death of Sandra Bland while in police custody. The police department's coroner ruled it a "suicide", but her own family has disputed that. And it seems odd that a woman would end it all as a result of facing just a short time in jail on trumped-up charges.
I don't claim to be certain of the facts in either the Sandra Bland incident or the Austrian doctor incident. There are some dishonest police officers in every country, and I personally think that both of those cases appear suspicious based on the limited information I saw about them.
I strongly doubt it was a suicide. The Australian police force were on the side of her killers, so they called it a "suicide" because they didn't want to investigate her murder.
