Anybody know if this case ever produced any suspects?

This was the brown pinto that supposedly would prey on truckers and gunned one down at a phone booth.

There is a preexisting thread and the victim's name is Dwayne McCorkendale.

No viable suspects, but it's been rumoured that the female suspect is a Jane Doe found dead in a motel room. Might have been in Albuquerque?

Thanks for the info.
