If you do a search on a reputable search engine on Czech diving and look back a few years, and look under Andrea Absolonova there are some results. They are all text only.
In regards to any money questions. She did not make really much at all. No royalties. And all extra I am sure was spent for expenses for cancer treatment and after her passing. Donations, also went towards treatment and now what is left is being set aside for a memorial. You can read on the Lea main page about how to donate any amount of funds you can. As her family is short of what it will cost.
I can assure that Andreas family and friends still are deeply in dispair over her passing. As in all families there are diffrences. Some have been made public, some I am sure have not. And like you have said some are RUMORS. Fact is. It has been well documented here that Andreas' sister and her mother, along with many close friends and other loved ones loved her very, very much. And we miss her still, more than words can say.
Remember, unless you hear from a close friend or a family member personaly. It should all be speculated as rumor. Some very close friends and some of Andreas family read this board from time to time. Do we really need to seek answers for speculation and rumors here?
If there is anything we really need to know I am sure that it will be posted, in time. Anything else I will be respecting with the dignity and privacy of the family in mind. In my opinion everyone else should too.
