I'm half very surprised no-one has done so, reedus -- and half not surprised at all.
I was just watching Cold Justice, and Jane's case came to mind as one I'd LOVE to see those two wonderful ladies get their teeth into... I also thought it'd probably be a good case for VIDOQ. But in both instances, the request has to come from LE... so there's two resources out the window, probably.
As it is with another several decades-old cold case I've become quite invested in, I suspect the local cops are the MAIN reason the case went unsolved all these years, so they're loath to have someone else look at their dirty laundry. So nothing happens, and nothing happens, until everyone gives up talking about it, no-one's making a fuss and the case sinks quietly to the bottom never to be seen again.
Only in that case, people did not give up. Dedicated forums, a documentary and a follow-up doco... and eventually people came out of the woodwork to talk about painful things, memories, family members... It became clear to anyone with eyes that this case was NOT disappearing. And finally, the local LE now seem more willing to re-open the investigation.
Squeaky wheels, for the win. This is why I think keeping discussion going is so vital. Even if we're all feeling a bit like "what's the point, we're going in circles"... But all it takes is a few people to keep those circles spinning, for years if necessary, and sooner or later someone else joins who has much to add.
Like Don!
What about Discovery? And what large-scale publications would do stories about cold cases that aren't the Black Dahlia..
