0430am - Corrie's phone leaves the BSE mast area (approx 5km radius).
0458am - Corri's phone enters the BM mast area (approx 5km radius).
0800am (approx) - Last signal from Corrie's phone in BM mast area.
Its important to not that the speed of a HGV/LGV (bin lorry) would be recorded on the tachograph uplink. Also, on A roads by law it would be limited to a maximum speed of 40mph so an over speed (speeding) would be registered as an illegality and flagged up).
Additionally, bare in mind the radius of the mast 'signal acceptance' area. Just because BSE is 12 miles from BM doesn't mean to say that the signal has to travel that far. The total distance of 12 miles, minus signal acceptance areas of 3 miles each (6 miles) means the signal ONLY has to travel 6 miles to register from one to the other.
What bothers me with this timeline is I can't figure out why the phone takes an hour to leave the BSE mast area. Was the bin lorry doing other pickups in the BSE area for an hour before traveling on to Barton Mills? Or was the phone still on Corrie's person, which would mean Corrie stayed there for an hour? If we're hypothesizing that Corrie was picked up by a car at around 3.30, which ultimately went to the Barton Mills mast area, then what was happening for that missing hour?
I see the police timings as being very loose. I don't know which times are 'correct', but I have been working on the assumption that the times given by the police do encompass the actual times, even if they're not stating actual times. I thought the first timings we were given by the police were of the phone going from BSE to BM in the 4 to 4.30 timeframe, which put Corrie's phone in that loading bay for half an hour before the bin lorry turned up and then drove on to Barton Mills/Mildenhall. But we can't see any evidence from the CCTV of the few people picked out for the pod footage to suggest that anyone saw anything in the loading bay that made them look over there, so we've thought Corrie probably left the loading bay in a vehicle (or possibly on foot if he could evade the CCTV cameras) within about five minutes of entering the loading bay, which would be approx. 3.30.
I feel like I'm rambling now, but if you go by other timelines, then the time Corrie's phone stays on the BSE mast seems to be even longer, but if Corrie was picked up by a vehicle, then why this stop-start-stop-start pattern? Why get picked up from the horseshoe then stay in the BSE area for up to an hour, and then move to the Barton Mills/Mildenhall area?
I wasn't putting any stock in the mention of the bin lorry driver spotting the teens at 4.20 because everywhere else seemed to say they were only picked up by CCTV. If it was the bin lorry driver and he was still doing pickups in BSE until 4.30, that would explain the phone timings. Believe me, I hate the bin lorry as much as anyone else, but if the phone was in the bin lorry and the bin lorry was in BSE until 4.30approx, then that matches the pings on some of the more specific timelines. And if the bin lorry wasn't in BSE until 4.30 (and wasn't how the teens were sighted) then I would think Corrie was more likely with his phone and was somewhere in the BSE mast area for an hour before moving on. This could be a very key time. This could be where something 'happened' and went wrong, and the ping to Barton Mills/Mildenhall are Corrie and his phone but post-traumatic injury as opposed to voluntary movement.
