It seems like all of the witness accounts, information provided by close friends, as well as the actions of Robyn herself seem to all contradict one another.
It really is baffling.
You'd think it would be easier to have her in on the insurance fraud than kill her.
Of course another possibility exists that this man was obsessed and can't handle rejection well just like with past women. He thought there was more to the relationship than there was (even if she was seeing him, she didn't care for him like he wanted her to), is very possessive, and figured if it didn't work out, he would just cash in on the death after brutalizing her(I don't even want to imagine what the last moments could have been like). He became irate in the past with her but she allowed herself to be subjected by his abuse for some reason(possibly he took care of her in some way in which prevented her from breaking it off)- such as the awful texts her friends said she received. He referred to her as his lover in letters (this again she allowed, whether true or not) which made the boyfriend finally come to the realization he wasn't gay. The boyfriend gets mad and moves her stuff out of his apt. I honestly feel sorry for the guy; it must have been torture knowing she was with another man this way on vacation. Yet, her friend states there was no current relationship with this man? Maybe she takes a vacation thinking it's as friends (I don't know how), when she finds out they are sharing a room and possibly a bed. She probably had trouble even sleeping in that position which is why she was up at least til 2am. This would suck! He becomes more and more scary & threatening and she decides to play along with his fantasy to appease him calling him her "husband" (whose idea was that?).. and like others said, it wasn't long after that message to her bf that something happened! Whether he was planning this all along or not, it may have set him off early. But for some reason, this guy is trying to prove to himself and the world they had a relationship- he claims they saw eachother 2 times a month, there are now witnesses who say she referred to him as husband, he wanted everyone in the restaurant to know who they were by making a spectacle of himself, and he leaves photographic evidence behind. It seems like he intentionally wanted to hurt the bf as well.
