As a runner, this case speaks to me.
If he was dressed for running/jogging (I want to know exactly what kind of tan pants he had on), he was probably an avid runner/jogger. So what missing men fitting his age who regularly ran or jogged and have been missing since 10/01?
I knew two middle-aged men who regularly ran and jogged who dropped dead while running/jogging.
He was slightly overweight but this doesn't mean he wasn't an avid jogger- he just may have liked food even more than running.
I feel like this case can be solved so easily based on his running attire (to show if he was a reguar runner) and also there's a PM pic taken so very soon after his death.
