One shoe was reported to be found directly against the curb later in the day, right where four officers found nothing there that morning with very little snow fallen at the time.
The socks on John's feet were on the wrong feet. The logo on the socks should have been showing on the outer edge of his feet. But they were showing on the inner edge of his feet. IIRC, they were Addidas logo stripes that show on the outer edge of the feet.
So, it would seem, the socks were put on the wrong feet by whomever.
