The police update states that Robyn's last confirmed sighting is now at 1.15am on Friday 28th November.
She was seen near the Esso Garage on London Road, heading towards Morrisons.
She was also wearing a different top; instead of a dark coloured jumper, she was wearing a lighter black top.
What's significant about this new later sighting, is that there are only 3 viable ways that she could have got from Bathwick Street to the Esso garage in London Road.
1) by walking across the main Cleveland bridge that links Bathwick Street to London Road, but which is full of CCTV cameras.
2) same as above, but via a vehicle
3) via a little known foot bridge; Grosvenor Foot Bridge, that links Kensington Meadows; that forms part of the River Avon footpath north of the river, directly to the Kennet and Avon Canal towpath located south of the River.
Note that It's possible to walk through the Morrisons car park to the corner, and then walk down onto the footpath at the far edge of western edge Kensington Meadows, and then walk north-east along the river to then reach the Grosvenor Foot Bridge, which then takes you over the River Avon, under the train line and then directly onto the Kennet and Avon towpath.
Heading south on this towpath would lead you to come out onto Beckford Road, which is very close to where Robyn was seen heading to earlier that evening (but from the direction of Bathwick Street; ergo, from the opposite direction)
The previous sighting of her in Bathwick Street and heading towards Beckford Road, means she was heading directly away from her later sighting near the Esso Garage in Morrisons.
That means that at some point she had to either turn around, head back up Bathwick Street and cross the river via the Cleveland Bridge, or get into a vehicle, or continue her walk towards Beckford Road, and then walk along the canal foot path up to Grosvenor Foot Bridge, walk across and come out at Kensington Meadows, walk along the river to the far end of Kensington Meadows and then come out in Morrison's car park.
This is the reverse route that she may have been attempting to make when she was last seen heading towards Morrisons. The supermarket would be closed by then, so the only reason to go there would be to either walk along the river, go to a vehicle, or use the cash point.
There's also a self storage facility located close by.
I would suggest that it's unlikely that she walked across Cleveland bridge, as she would have been picked up by multiple CCTV cameras.
Her change of top also means that she had to have deposited her thicker jumper somewhere relatively close by.
The timing between sightings and her relatively close physical proximity for those 2 sighting means that there's a high probability that Robyn spent the time between sightings within the same geographical area.
A house, flat, or even canal boat could be a viable option.
If I was leading the case, and Robyn wasn't caught on CCTV cameras along London Road, then unless she was in a vehicle, I would be looking for any evidence between the Morrison's car park, possibly including the self storage facility, then through to the footpath leading down onto Kensington Meadows, north along the River, across Grosvenor footbridge, under the train arch/trainline, south along the canal towpath, in canal boats moored nearby, and then back into Beckford Road.
Note that there have been recent works and improvements in that section of the River close to Cleveland Bridge, which I believe encompasses the area north of that bridge. That could be significant.
