I was just looking for updates on the location of Barbara's remains, and ran across this older article. I'm just re-posting and bringing some key quotes here to support those, like myself, that believe that the possibility of foul play still exists, or believes that this is still the most likely scenario. Her son certainly felt that way, as quoted below from the article linked.
"Family members suspect foul play and are seeking answers.
In a statement written by several members of Barbara Thomas' family based in Hong Kong, she is described as an avid and regular desert explorer along with her husband, Robert.
"The chances she became lost or disoriented in the five minutes between her husband reporting last seeing her, and him (realizing) she was missing, are highly improbable," the family said in the statement shared with The Republic.
Also, a reminder of the very close proximity of her trip to Hong Kong, which I know several discussed as being a potential trigger IF this was a domestic violence situation:
"The family members said Barbara Thomas was scheduled to visit them in Hong Kong on July 23.
"Barbara does not have a history of any illness that we know of. We have no reason to believe Barbara would walk away from her husband, or disappear in the manner she has. Especially not so near to a trip to Hong Kong to visit her younger brother in (the) hospital," the family's statement reads."
Family members of Barbara Thomas suspect foul play in disappearance
Perhaps her family knows something about the situation and/or RT that we don't. Personally, I remain on the fence pending the disclosure of the location of her remains.
