Florida and Texas both have pretty sizable Russian communities, of course I'm not sure how long they've been there. It's possible that this was a transient woman or beaten wife, but I find it harder to believe that the family and/or neighbors of this little girl would have been completely unaware she ever existed throughout her whole entire approx. 2 years of life than her possibly being foreign born. Back in the 80s we didn't have phones and internet to distract us so we knew our neighbors, and families drifted apart but not as far apart as they do now.
But, Bella Bond wasn't noticed by many, which was a very odd in this internet age. And now we have the Bob Evans guy whose wife was never reported missing until very recently, even though she's actually been missing for decades. Perhaps this will end like that case, with the family coming out of the woodwork eventually when they realize their family member didn't actually move out of town? Idk.
The only thing I actually know and don't have to make wild, crazy guesses about is that this case is one of the ones that really bothers me. Well, they all do, clearly. But I'd especially like to see this one solved.
