I'm assuming the bin lorry went up the A1101, which would appear to be the most direct route to BM. If Corrie got out in the vicinity of Tollgate Bridge, which is almost exactly a mile away from the HS, that is definitely on the way to Honington.
Yes - you can walk that way back.
A lift from the Bin Lorry would have saved him 20mins walking time, not a massive amount. Plus Corrie would have had to tag along with him to Waitrose, so it possibly would have saved him 10mins overall assuming that was the last bin pick up in that area.
I just don't buy it because I don't see how Corrie disappears. Although it isn't all that complicated it seems over-complicated.
-Corrie is in horseshoe for 30mins nobody sees him.
-Corrie chats to bin man at 4pm and agrees a lift.
-Corrie saves 10mins by getting a lift down the road.
-Corrie leaves his phone in the cab by accident.
-Corrie walks home and gets attacked by pigs, drowns in a puddle, trips over a cow pat, or gets ran over and the person driving feels it was their fault so they bung Corrie's dead body into their car and drive off.
+ the bin lorry driver would unnecessarily be lying to Police. Would he get in that much crap for having a passenger in his wagon? Surely all the media stuff about this would encourage him to tell the truth if he gave him a lift.
I much prefer....
-Corrie, with his phone, gets into a vehicle which heads to Barton Mills........whatever happens next who knows.
