I agree about the three pieces of tape found by the fence. What I'm waiting to hear more about is the fourth piece of "Henkel" tape at the disposal site, the one that was found close to the remains. That piece was found by LE after the remains (and the first three pieces) were removed by the ME, and it was sent off to the FBI labs. Unless I've missed something we have never seen it mentioned subsequent to the documentation of transfer to the FBI.
Also, it seems like we're still missing an FBI lab report on trace fiber evidence for the four pieces (three from site, one from A's house) that we have seen some results on. I have to go back and re-read, but I seem to recall a mention of those being forwarded to another FBI lab for just that purpose.
It still puzzles me that no other duct tape, "Henkel" or otherwise, was found at the A's. Maybe it's just my sense of 'good old, red-blooded American, do-it-yourself' propriety, but I just can't imagine being a healthy adult male homeowner with a garage and two storage sheds and not having a roll or three floating around. Even if I had tossed some as part of a cover-up I would have gone out and replaced it. Maybe especially if I had, just because it would be too weird to not have any around. I have to wonder if GA even knew he was in a duct tape free zone until the searches.
