She is allegedly a hot-headed, volitile, mail order bride from eastern Europe.
I guess you get what you pay for.
...specifically, she is Latvian.
This action is well known in the South American countries. You become a mail-order bride; get to the USA; marry a citizen; murder the citizen and collect all his money.
Actually know of a case that was for real - woman from Columbia killed her husband believing she would inherit all the family fortune .. it turned out the sister of the victim was the Dual-Heir .. and the new wife got nothing.
