Witnesses Who Are Suspects

[Damaso Marte]

I'm surprised that Schwartz or Dimshitz have never been floated as suspects.

[Wickerman]

You can add Joe Barnett & Joseph Levy as being identified as potential suspects, along with Michael Kidney, Robert Mann & I think McCarthy was a brief suggestion at one point.
Not all as Jack the Ripper though, some as just responsible for a single killing.

[Barnaby]

Of course there is Cross/Lechmere and Hutch.

I always thought Richardson was interesting because he can be placed at the crime scene with a knife. He could have lied about the time and the knife produced at the inquest.

Others?
