What Happened to the Fort Worth Trio? – Things We Find in the Dark – Medium
Fyi...
In a radio interview that I posted in thread 3, Rachel's brother claims that he tracked down the *elderly* some 40 years later and inverviewed her.
"The article also cites one lead the police department wasn’t able to track down. In 1975 the Vernon Daily Record reported that an unidentified elderly woman told three store clerks she’d witnessed a man forcing a girl inside a pickup truck on the day of the disappearance. She also said there were two other girls and a man already inside. She didn’t report this sighting to law enforcement, however, despite numerous appeals for her to come forward. They were never able to find her."
