This case reminds me of Jodi Huisentruit as well. The small stature of the man makes him less likely to be Caucasian, in my opinion, although I know a couple of men that short. This makes me agree with those who think he is Hispanic, possibly a migrant worker, working in the construction trade. He may have been quite familiar with the area where he parked the car, having done work there before. Unfortunately, this makes him much harder to locate, because he doesn't have a fixed place of work he goes to every day.
