If you read his bio he could be a witness. My guess is that he is a dub:
From Canary Islands Press Website (bio of J J Luna):
In 1959, J. J. (Jack) Luna sold his outdoor advertising business in the Upper Midwest and moved with his wife and small children to the Canary Islands off the coast of West Africa. Outwardly, he was a professional writer and photographer. Secretly, he worked underground in an activity that was at that time illegal under the regime of Generalissimo Francisco Franco.
In 1970 Franco, yielding to intense pressure from the western world, moderated Spain's laws, leaving Luna free to come in from the cold. By that time, however, privacy had become an ingrained habit. In the years that followed he started up various low-profile businesses, built them up and then sold them.
Luna is currently an international consultant specializing in personal privacy. He usually meets with individual clients or small groups at one of the waterfront hotels in Vancouver, British Columbia
