In regards to the GF... sometimes it seems we switched from the presumption of innocence until proven guilty... to guilty until proven innocent. All we really know is that she has cooperated thus far, is not hiding, and has returned to the US when requested.
IDK, although the ability to wire $100,000's of $$ is soooo not in my capability, I guess I do not see anything that super odd about a relatively wealthy man, when contemplating something that would kill 59 innocent people and also likely result in his death, to send $$ to his girlfriend who is out of the country. Even if she is not involved at all except by association... this is still going to be a mess for her, hiring a lawyer would be prudent and would require funds.
Such a horror. My sincere condolences to the families of the victims.
