Ah..today I went to the Archives again. I can't believe this is my last day of vacation.
I'm almost positive that I was wrong about Vivian and Pearl Loge being the same person. I took a close look at the original photograph and Pearl Loge seems less hardened; she also talked up a storm. Vivian Chase was notoriously closed mouth when questioned. Also, agents noted the resemblance to Vivian right away so I'd tend to think that they would have tried to match fingerprints with Vivian's first thing.
Another thing, Percy Fitzgerald, one of the August Luer kidnapping team stated that Vivian was only used to gain entry into the house. Some how that makes me feel better about her because it was an incredibly unprofessional job. I like to think she did her part and then let the rest of them make a mess. Looks like I have some fun reading tonight.
