On Sunday, April 19, 1953, at 8:30-ish in the evening, Ronald H. Tammen, Jr., disappeared from his second-floor room in Fisher Hall on Miami University’s campus in Oxford, Ohio. He left everything behind — his wallet, his string bass, his car, his clothing, even his toothbrush. No one could figure out what happened to Tammen. Miami University officials were mystified, the Oxford  PD outwitted, the FBI flummoxed. Since the spring of 2010, I’ve been conducting my own search for Tammen and what his disappearance might tell us about this enigmatic 19-year-old who landed himself squarely in the middle of one of the most bedeviling mysteries ever to hit the state of Ohio.

New to this site? Welcome! Currently, a bunch of us are awaiting word from an interagency panel to determine if my theory on what happened to Ronald Tammen is upheld. Once that happens—either way—everyone who follows me (through the blog, Facebook, or Twitter) will be notified. In the meantime, this is the perfect time to bring yourself up to speed on the story as well as to start rummaging through the blog posts, which I’m still writing on occasion, when there’s something important to tell you. Also, if you have a lead, comment, or question, you can use the contact form in the top menu to communicate with me, or email me at rontammenproject[at]gmail[dot]com. Thank you!

What Ever Happened to Ronald Tammen?

(WXIX two-part news story)

In early spring 2020, right before Covid-19 upended all of our lives, Chris Riva, of WXIX (Fox) television in Cincinnati, began filming a news segment on the Ronald Tammen case. Chris was especially interested in interviewing Marcia Tammen (Ron’s sister) for the segment, so he drove to Marcia’s apartment in Wooster, OH, and spent the morning interviewing Marcia and me. Sadly, it was the last time Marcia would be interviewed on camera. She passed away in August. The two-part segment aired in November 2020.
