Okay, to brainstorm with this post, not to trash the post as I think it's good.
Either the phone was in the bin OR Corrie (who went into that loading bay area but is never seen by CCTV as coming out of it) jumped on the back of the truck with his phone.
The load was measured at 11kg, suitable weight for a pickup of a bin of paper, but not for a grown man. Therefore, Corrie was not in that bin and not emptied into the bin. That he didn't get emptied out of the bin lorry at the other end (and they can't seem to tie the phone to the emptied load), says Corrie was not in the bin, and maybe the phone wasn't in the bin, but was on Corrie's person while he was otherwise attached to the lorry.
The phone makes it to approximately Barton Mills, from the pings. Barton Mills is also approximately the location that the bin lorry went to, and where its load was emptied. Phone not found there, Corrie not found there.
Corrie could have hopped off the bin lorry (with or without his phone) before the lorry drove into the recycling centre. If he was without his phone, then the phone should have been found either in the load or by someone in the recycling centre. Maybe he still had the phone on his person when he jumped off the lorry.
Corrie jumps from the back of the lorry (or falls asleep again and slips off?) ... is hit by a car, body goes into a ditch, the phone battery is still alive and pinging that location until the battery goes dead at around 8 am.
Which is all neat and tidy, except for the fact that the searchers haven't found either the phone or Corrie in the vicinity of the last ping.
The timeline seems "straight forward". At least for the phone.
3.24 Precisely CCTV of Corrie leaving the doorway heading to "loading bay".
4.00 Approx. Bin collection in "loading bay".
4.30 Approx. Bin lorry triggers motion camera in Barton Mills.
Occam, and his shaving implement, would say the phone was in the bin, being that the phone takes approx. half an hour (28 minutes) to get from Bury to Barton AND both Corrie with his phone were in the exact same place as the bin lorry.
The next logical step is to ask, who put/placed/carried the phone into the bin ?
And the simplest solution (at 3.25am in the morning) is that he did, when he clambered into the bin.
Since the phone hasn't been found "at the most logical place it could be", then neither would Corrie.
The biggest problem with that "solution" is, "surely to God, being emptied into a bin lorry from a bin would wake up the most drunk of sleeping beauties" .
Out of interest....what did Corrie do with the remains of his take-away ? The rubbish bit ?
He didn't put his phone in that bin with his rubbish did he ???
