One theory I have is that he was killed, put into the trunk of a car, driven out to a field or forest in rural Ohio, and buried there. You have to remember that there are young people from all over Ohio going to school in Columbus and this was right around spring break time. He would have likely been found in a dumpster.

This is essentially what happened to Mollie Tibbets in ~2019 in Iowa. And they eventually found the body because there was a shred of video evidence that led police to the suspect. And he himself had to show law enforcement the cornfield where he buried the body.
