I've been following but haven't chimed in yet.
I would really be interested to see when he purchased the bag, tarp, etc from Wal-Mart, was it Tuesday, Wednesday, Thursday.
I was also wondering if the text sent to Greg Borders was sent from Tina's phone by MH, maybe an effort to delay him from coming right home, I wonder if she sent him messages like that often.
I am also wondering if he may have used the bags/tarp to transport them, but placed them in the water in an attempt to cover his tracks. Not sure it would matter seeing how he probably left DNA/fingerprints everywhere.
I was thinking about him going to the gym regularly, if he had no electric, I wonder if that meant no hot water for showers. Gyms normally keep very good track of sign ins, and if he showered at the gym I am guessing there could be some blood evidence there.
