This just gets odder and curiouser, doesn't it?
I found the link on the Chinese Embassy in Mexico site (Embajada de la República Popular China en México), so it appears legitimate.

JR has taken down the link to that nwasianweekly article from the Help Find page, and I also see that he commented this under that nwasianweekly news piece:

Dear C,
The Oaxaca police put on quite a show for Jennys parents. How could she be traveling for almost two months without any money?? I have her bank records. These types of stories produced wild rumors with NO substance, and deviate from the true investigation that my legal and investigative team have put together. We need to focus on her last substantiated sighting, which was with the truck company with Corona logos. We are working hard on that PROVEN lead, not silly rumors."
As of right now, on the page the link is still there to the nwasianweekly, on update #56.
Just wanted to add that of course the information comes from the Embassy themselves, but what is interesting is that it sounds like the Embassy gave quite a bit of assistance to Jenny's family. Hasn't JR being saying that they have been of little help?
