Came across an interesting find while searching podcasts on Spotify.
A podcast called, "gone cold podcast - texas true crime" has an episode on WCJD. It doesn't share any new details about her or the case that we don't already know and it does go into quite a bit of detail about truck stop serial killers (which I do think is interesting and relevant to consider for this case given where she was last seen). Anyhoo. The podcast also explains a possible suspect by the name Robert Allan Autry. On June 22, 1984,Robert Allan Autry entered the home of 59 year old Zola May Fraiser (without force as he was familiar to her and her home and seen there on many occasions) in Huntsville. Zola lived alone and was depended on a wheelchair. Robert Allan Autry brutally beat her, sexually assaulted her, and strangled her death. The most INTERESTING part was Zola also was found with a deep bite mark (like WCJD). Robert Allan Autry spent the next 2 years in a mental health facility and ultimately hung himself.
Apparently, Robert Allan Autry and his brother, James David Autry had a history of being in and out of jail. The night of October 31/November 1, 1980 James (brother) was in prison right in Huntsville. Robert Allan Autry (the one that murdered Zola May Fraiser) was not....
This is all a dead-end lead given Robert Allan Autry is now dead but I do find the way Zola May Fraiser was murdered, especially being found with a bite mark to be very chilling and curious for this case.
