Thanks Granny for the update. Here's an article from Nov 5 on the discovery.

PALMER — The Ellis County Sheriff’s Office is investigating human remains found by hikers Sunday. Deputies were dispatched to a wooded area off of East Campus Road in Palmer.
“I have no reason to believe that they are going to tie into any existing sheriff’s office cases,” Brearley said. “But until the remains are identified through DNA, then it is just a guess where it may come from.”

There's only one truck stop in Palmer that I could find. Here's a map from there to East Campus Road.
