Interesting. I am not sure how she would have ever been able to use any of those funds, though, without giving away her location, or new name. If she was going by the name Ari in Costa Rica, and let's say she opened some sort of bank account there eventually, would she have been able to log into her KA account and wire transfer funds from it to Ari's account without authorities knowing? Probably not, because they probably had tabs on the KA account looking for any activity.
Not to slam HIM further, but this also shows his naivete - who TRANSFERS that amount of money to a woman you don't think you'll marry, whom you've broken up with off and on repeatedly, hoping she'll invest it wisely for you? He should have kept it in his name and just had her manage his account. Easily done! Either just by sharing a password or adding her as a manager to the account. By giving her the money, assuming his name was never on the account, the funds and interest earned would be hers unless she set it up as joint or him as a beneficiary.
Edited to add - so does Colin now have to sue her in a new court case to obtain the funds back?
