Murder She Wrote Conspiracy?

Anyone remember this show? So I was sitting here at work, perusing the old yahoo question boards... What did you expect me to actually be working? Anyway, that show just popped into my head and I couldn't help, but think that old bitty must have been cursed or something. I mean, seriously everywhere she went people were getting bumped off.

Now the conspiracy... you think the sheriff... um Tom Bosley, whatever his name was, would have put two and two together and maybe pinned one on the crazy old bat. Seriously she just 'found' evidence against everyone else and no one questioned it. Theories that maybe she was some sort of serial killer?
