All that is known at all, as far as Lori Peugeot goes, is there is a similarity in appearance and date of birth. DNA testing was underway, but no one is privy to the status of that and it actually should already be known whether Lori is Sharon or not, so I'm leaning towards that she is not.
What has became known is that another family member had Sharon for a time in the early 70s, now whether Floyd had her first gave her to that family member and she then returned Sharon to Floyd, or if that family member had Sharon first and Floyd took her is unclear at this point still. This family member is in Alabama. As I stated before, there is a mountain very near to this location called The Suzanne Davis Summit (may be where her name was derived) it is in Cherokee County Alabama and Floyd is really big on their Cherokee Indian Heritage.
Hollow recently found out as well that Floyd briefly worked at a Fiberglass Factory in Fairburn, Georgia briefly before being sent by plane to Chicago Illinois. The Freedom Village Post Card may not necessarily have been a place near Chicago as much as a temporary post office set up to sell postcards and such for The Freedom Train, which ran in this time period across the United States and was up in the Chicago area when Floyd should have been there.
Also, the facts of the 1973 abduction of a woman near Atlanta have become a bit more clear. This happened at a Zesto Fast Food place in East Point. Floyd also worked at Avis again in 1973 before this abduction took place which caused him to flee to Chicago.
