I posted the following video in thread #13, page 3, post #59 but didn't think too much about the comment made by AS (neighbor that heard the dogs and talking men at 6:30 am) at 2:30 in the video. After all the theorizing going on about possible cartel involvement, I thought I remembered her saying something about it but didn't want to post without being able to link to the video. I finally figured out which video it was, so here it is:

AS "I have heard speculations on that the family is involved with drugs, the cartel." Again, this starts at 2:30 in the above linked video.
Just putting this out there, fwiw, as it is a linkable MSN video about the local rumors wrt a possible cartel connection.
