Not sure how much of this is appropriate to share on here, happy to delete this if it breaches TOS:
Yes, the comments on FB indicate that Lori (I'm going to call her Lori because that's how she's referred to in any news articles, missing person's flyers and in the posts on social media by those form her community) attended Northside Jr High. It appears that people responding to the post on the Special Collections FB page have checked both the high school and Jnr High Yearbooks and there are no pictures of her.
There is a comment from a man on the Grasslands Community FB page that says he knows that the PD have a full colour photo of Lori because he provided it to them (I'm not sure of his relationship to Lori).
The overwhelming theme of the comments is that the majority of people from her class and community largely don't remember her or this event, barring a teacher and a couple of others. Even a woman who worked at the CY Market at the time doesn't remember the incident. Those that do remember recall her being a runaway.
There is speculation from some that Lori was the sister to a man with the initials BS who has a public profile but researching him, I can't find any mention of him having a sister, let alone one that disappeared so I'm not sure if that's true, and if it is it's probably not really relevant anyway.
The Marcia Trimble case in the same area at a similar time got huge publicity - so I am guessing that Lori's case was very much seen as a runaway rather than an abduction. I would love to know more about where people thought she was headed if she was indeed hitchhiking/'running away'.
