James Negley Herz, 78, disappeared while traveling the country in his 1994 Ford Ultra RV. The last known contact was a letter to family postmarked from Quartzsite, Arizona, on February 24, 1998. After that mailing there was no further communication and his family reported him missing.

The case went cold until September 22, 2012, when Herz’s RV was found abandoned in a remote area near Kingman, Arizona, more than 100 miles north of Quartzsite. The vehicle’s location did not reveal Herz’s fate, and no confirmed sightings of him have been reported since the 1998 letter.

Few other details are available about his movements between Quartzsite and Kingman, or how the RV came to be abandoned where it was found. If anyone knew James Herz, his travel plans, or saw the RV in the years after 1998, please share what might help clarify where he went.
