No known tattoo for this missing woman (no rose on hand), but with the circumstances taken together and the resemblance to the images for the Jane Doe, I really, really wonder. Jane Doe to left, Deborah Lois Dean to right:

Deborah Lois Dean disappeared while she was taking Greyhound from PA back home to Tuscon AZ. (Family were supposed to meet her in Phoenix.) Her last known location was St. Louis 5/3/85. She's 23 yo, 5'2", 125lbs. Her purse was left I guess at a truck stop outside St. Louis along the St. Louis route, and it was ultimately sent back to the family. Deborah never made it back to Phoenix or Tuscon. More Deborah Lois Dean:
Both of Deborah's earlobes are pierced, one ear multiple times. She had an athletic build in 1985. Often changed up her hairstyle. They mention medication that made her teeth slightly greenish hue, I don't see that at all in images of Deborah's teeth when she smiles, so I'm discounting that. Maybe it's too faint to make a difference, maybe it's only certain teeth in back of mouth, not sure. Deborah normally wore rings, earrings, necklaces, bracelets and a wristwatch, so a lot of jewelry, and a smoker like the Jane Doe. I saw in a source that the Doe's remains were frozen, at least for a time, before discovery, and LE seemed to think the time of death may have been further back than I'm seeing reflected on other sources.
Just looked it up and saw that PA to St. Louis on Greyhound takes maybe (?) 12 to 20 hours. Would it be possible Deborah struck up a conversation with someone else on the bus, and that "someone" had a vehicle waiting in St. Louis? And that this individual perhaps took her out for a coffee near the station, offered her a ride somewhere? OR that they actually went together to some cafe/truck stop as they were en route to St. Louis & she'd forgotten her purse there. Maybe he noted he'd drive her back to retrieve it. (?)
The location/circumstances of where/how they found the Doe throws off SK vibes more than trucker, jmo. Someone went to considerable trouble piling rocks on top of that Doe for concealment, and that appears to be one very remote location. I cannot streetview or find any images as of yet, going off limited descriptions available. But I'm getting more "hiker" (& perhaps somewhat smaller vehicle) than "trucker" from such maneuvering, but again, jmo.
Have thought for a while this Doe was a traveler and Deborah is one, too.
