A lot of college kids were also prison guards, because in Texas you can be a prison guard part time, you can also tutor inmates to help them get GEDS, you can do walk throughs, observations. To be a prison guard now you don't have to do much, so in the 80s, I'm sure it was even more laxed. My only reasoning for bringing up the college kids is that the Hitching post had all kinds, even families just doing to fuel up and get food. So the suspect list is super long, cops, truckers, guards, college kids, mechanics, a random serial killer, an inmate recently released.... BUT I do feel she was in route to trying to get to the Ellis Unit... It was 1980, Saturday night, Halloween.... Lots of people were out and about. I'm sure the Hitching post had a after bar hours crowd.
