First of all, thanks for reading!
I haven't read that one actually! I was actually hired to write a documentary script for this case (not released yet), so I dug more into primary sources. I'll probably read more books in the future, so I'll look into that one.
The main book that's well regarded on the case is Leonard Rebello's "Lizzie Borden, Past & Present." Unfortunately, all copies of it are $450 and the e-version is a bunch of scans I can't mark up as a pdf. That was like...the first hurdle I had researching this case. Ugh. Sorry. Just had to rant about that. I guess it was only printed once.
The menstrual rags often get taken out of context. The men at the scene had also just seen 2 brutally murdered bodies, so they weren't going to squirm about the bloody rags. They were actually brought in for testing. Idk what kind of testing since it's not like they had DNA analysis back then but nothing came out of them. They were considered.
I think both of those theories are a close second and third for me. I think someone else having something to do with it and Lizzie sneaking them in and out of the barn makes a lot of sense too. I'm not convinced Bridget had nothing to do with it either.
With a case like this, after so many years have gone by and our imaginations have gone wild, I'm sure the truth is actually quite anticlimactic in comparison. Haha. That thought is how I keep myself from trying to jump to conclusions.
It's a hell of a case. It always has been. It's just a great case to discuss. After I published this, at home we started a friendly argument about whether she did it or not.
