I'm pleased to see that we are finally permitted to discuss this topic. I haven't had the time to read through all of the many threads on this topic, so please forgive me if the three observations I am making below have been already covered.
Firstly, although the divorce papers stated that AY and EB resided together until on or about 5/29/08, AY clearly stated on Facebook on 11 November that they had been separated for 3 years. Thus, Elisa didn't leave Aaron to go to Australia.
Secondly, Queensland's CRIMINAL CODE 1899 - SECT 360 reads:
"(1) Any person who--
(a) being married, goes through the form of marriage with any other person during the life of his or her wife or husband; or
(b) goes through the form of marriage with any person whom he or she knows to be married;
is guilty of a crime, and is liable to imprisonment for 7 years."
Therefore, in answer to a previous question, Adam can be charged with bigamy in Australia if he knew that Elisa was already married, even if he himself was single at the time.
Thirdly, my legal mind cannot but help ponder the possibility that Elisa did not commit bigamy when she married Adam. If in fact she wasn't divorced from her 1997 marriage to Jeffrey Russell Allred when she married Aaron in 1998, then that would surely void her marriage to AY. Thus, she may well have committed bigamy by marrying AY, but not in fact by marrying AB. This of course assumes that she was divorced from JRA before she married AB. I am assuming also that somewhere along the line her 14 September 1985 marriage to Jerry Winkler was legally dissolved. I read that their divorce was granted on 29 January 1986, but I query whether that is correct given that it is less than five months after their wedding! What a tangled web!
