My first post. I've read all the threads. I have a couple of things to note. This is the first:
Regarding the clothing worn by the person in the CCTV camera footage obscured by the supposed spiderweb, when I first looked at it the person seems to me to be wearing very tight skinny jeans that are light in colour. Yet I've read some people suggesting the person has bare legs, some suggesting the person is wearing shorts and others suggesting the person is wearing three-quarter length cycling leggings. The footage is so poor it's impossible for me to even guess at what footwear the person is wearing, so perhaps there's not much point in the question.
Then we have the sighting above from the father of the witness from the house in the park, who said the man his son saw running "was not dressed for the weather". I wonder how good a view the son had. I wish he had clarified what "not dressed for the weather" meant and what the person he saw was wearing.
