I’m thinking another reason. I’m still thinking JD was not in those bags.
1.I don’t think he had the ability to do the unthinkable in the amount of time he had, or the ability to do it cleanly and with an unmanageable time line. He had to get in and out fast.
2. This crime was preplanned. If he planned on that means of disposal, he would have have taken better protective measures and the blood evidence would not have been there (of course, it could have come from the attack and it was a surprise, but then why was it so sloppily cleaned?)
3 . He had a preplanned prepared disposal site, just like the entire event was preplanned.
4. He removed the clothes to delay identification, if remains were found at all.
5. A few bloody clothes in black bags might have made it to disappearance in a trash incinerator. If there were no pinging crumbs, the clothes would have been history.
6 why 30 bags? Stops? I think it legitimately was debris from construction sites that he mingle the cleanup materials and clothing into.
7. Human (large) parts may have been detected at trash facility. Too risky. But I’m thinking smaller identifying items may have neatly concealed within other “garbage” so they would NOT accidentally spill out and be seen. I’m thinking concrete.
8. An unclothed, degraded body with identifying features removed, Removed and completely separated from body, was placed in his prepared site. And I’m thinking he had more than one prepared.
Edit: major typo!
