I think this “theory” has been in the forefront following the death of Nicola Bulley, which coincided with a few other bodies being found in rivers elsewhere. I think naturally some are quick to make links but there is little evidence to support the idea of a pusher other than circumstantial.
We’ve also had a few in Bristol in the months before Jack went missing:
Vincent Le Goascoz - last seen 2nd December 2023 on Redcliff Street, found Redcliffe Quay 6th December 2023
Keith Marsden- Missing since 4th December 2023 from Blaise Woods, found in the River Avon 31st January 2024
Sean Teddy - last seen 6th December in Henbury, found in a stream in Hartcliffe 14th March 2024
I’m in no way suggesting there is a link, there are numerous incidents of people falling in or bodies being found in Bristol Habour and the Avon over many years. On the face of it links could be drawn but I think two of the deaths I’ve mentioned above are more than likely accidental. However, Sean’s death seemed odd to me (but I won’t go into that as it will detract from this thread).
