Who Thinks She's Innocent?
I'm not an expert on the subject and it's been a while since I researched it, but last time I did, it seemed like there was a ton of circumstantial evidence that did not add up to much.
If you think she's innocent, who is your #1 suspect?
Personally, I think she was probably involved in some way (knew of the plan), but didn't really wield the hatchet herself. I remember, back when I looked into it, that the uncle who was visiting was more suspicious than she was. He supposedly had an "airtight" alibi, but that alibi wouldn't hold up in today's courts.
Andrew Borden seemed to be universally hated by many people, so the suspect list was long, and Lizzie very well may have been the sole murderer, but I think there were more people involved than we know.
