The missing person's case of Jeff Joseph is such a complete mystery.
It is possible Jeff Joseph was murdered. He was involved in the drug trade.
It is possible he drove off the road during his trip and this was an accident. The area where he disappeared has many winding roads, and he might have been tired too.
It is possible he walked away from his life. While this possibility seems remote as there has been no sign of him since June 21, 2014, his green 1998 Toyota Rav4, license plate XMZ062, with LSU sticker in the back window, has never been found. But that fact that it was green also makes it very likely it could blend in with the vegetation as the area where he disappeared has lots of trees and other vegetation.
This is a unique missing person's case that I hope gets solved.
