So what do we think about the fact the four Oak Road witnesses still haven't come forward? Are there any possibilities beyond -
(a) they haven't seen the footage
(b) they were involved in some unrelated but illegal activity so keeping schtum
(c) they don't want to deal with police for some other reason
(d) they were involved with Libby's disappearance?
The walking pair have a very relaxed gait; they don't seem they have just committed a crime. Running man however does seem suspicious and might be linked with the cyclist in terms of one having witnessed the actions of the other.
He's seen at 1.13am just as Libby's reported missing on social media, emerging from the path at a hell of a lick for a jogger on an icy surface; he's on edge as he either reacts to something or glances over his shoulder to check something.
The visuals of running guy and the son's 12.15 witness statement are very similar: "The man he saw wasn't dressed for a night out. He wasn't dressed for the weather. He saw him running for around 40 yards, sprinting at times. He said he was on his own and he wasn’t looking back."
Because of the similarity, I'm going to assume this is the same slightly unfit running guy, and that our witness wasn't confused re time. What scenario could account for running guy being seen near the park at 12.15 after high-pitched screams from the pond area are heard; then again an hour on, still edgy and hunted-looking, still running, emerging from Oak Rd?
If I was spooked by overhearing screams from a park at 12.15, I wouldn't go back alone an hour later. But if I had just silenced someone, and was worried others had heard their screams, I might try to put a bit of distance between me and the scene. Once I calmed down, I'd return to clear up the scene; when I left for the second time, I would be extremely on edge; the rustle of anything, such as hearing a cyclist looping around the park, would give me a fright.
Any takers for the Double-Running Man theory? (Or maybe it was a glitch in the Matrix.)
