John Breckinridge Hart was 36 when he was last seen in East Lansing, Michigan, on April 15, 1997. Two aliases appear in the records, Jerry Lee Johnson and Timothy Allen Paupst, but there is no public explanation for when or why those names were used.

The clearest physical lead is Hart’s red-and-white 1990 Chevrolet S-10 pickup, Michigan plate 2764CW, which was recovered in a hotel parking lot near Detroit—about 80 miles southeast of East Lansing. Beyond that discovery, there is no widely available reconstruction of his movements after mid-April; no confirmed last conversation, companion, or reason for travel is documented. Investigators have dental records, fingerprints, and DNA on file, and the Bath Charter Township Police Department continues to list the case as open.

Did anyone in East Lansing, the Detroit area, or who knew Hart under the names Jerry Lee Johnson or Timothy Allen Paupst have information about his movements in April 1997?
