In researching this case further this morning, I came across a site wherein a poster states that a white sweat sock was found on October 28, 1989 (six days post abduction). The sock was found apparently about 100 yards from the abduction site, but the dogs couldn't track it any further. Its unclear to me whether to sock was prooven to belong to Jacob (but wouldn't it be interesting if this WAS prooven via DNA from inside the sock!!).
The site is:

Also, on that site, I found the name of the neighbor who was babysitting (Rochelle Jerzak), and noted that her father made the 911 call initially. I'm reading an outline of the 911 call just now....
I remember the sock now. I wonder how the sock got there, or was it dropped on purpose?
