I just read an article in the news about a new non-fiction book that suggests Jack the Ripper was really Jackie the Ripper- the infertile wife of a doctor who had been having affairs with prostitutes.
So... I actually think it's a little funny because when I see that, I imagine how a testosterone-fueled team might react if it did come to light that Jack is Jackie. They can have a new mascot, complete with petticoat.
Couldn't they do better than that? I think it's tacky, and if you learn more about how horrific the crimes really were, it's even worse.
Patricia Cornwall gave a very good argument at solving the Jack the Ripper cases. Her book, Jack the Ripper: Case Closed is a really good read, I won't divulge her theory, but it wasn't a "Jackie." Convinced me 100%.
