Checked DNA project website..these two are still pending....
If they were involved in drug smuggling, could be why no one has come forward...in fear they could implicate themselves in criminal activity. Drug deal gone bad? Hard to believe TWO identifiable faces are not recognized. Why hasn't one person come forward all this time ?
Whatever the motive for murder, it looks very much like a gangland hit where three shots are usual, especially the one under the chin, which is known as the 'insurance shot' to make sure they're dead.
If it was a simple robbery then why leave silver jewellery on the girl and an expensive 14 karat gold watch and ruby ring on him after going to all the trouble of removing any identification from them both, (if they had any on them at the time, that is)?
I think the girl has remained unidentified for so long because she was probably originally from some French speaking region of Europe, and that he really was from a French speaking area of Canada, as stated when he was at the KOA campground.
Calling himself Jacques or Jock and owning a ring with the initials JPF on it indicates he was probably being honest about his name at least beginning with a J. Whilst choosing to hold onto his far more desirable and easier to sell watch and preferring instead to part with this initial engraved ring, (with a birthstone denoting December which may have been a parental birthday gift), could reveal that it no longer held any sentimental value for him, possibly proving the break with his father as authentic.
I suspect the ring was a gift from his estranged father and as such selling it was an act of emotional revenge against this parent who had disowned him, in which case we could be pretty sure his initials really were JPF.
