Robert believes she might have been picked up. Their trailer was parked near a road and he thinks someone might have take Barbara while she was crossing the road.
He’s asking people in surrounding areas, including Las Vegas, to be on high alert.
He says if anyone did pick her up, he won’t press charges. He just wants her home safe.
“I just want my wife back and if somebody out there has her, which I feel somebody does, please drop her off at a safe place where she can contact us and that’s it,” says Thomas.
The Inyo County Sheriff’s office Facebook page announces SP found at 2:00 on July 15
At 6:00, July 15, the Inyo County Sheriff’s office update said no further information at this time.
The earliest MSM report, I can find, with information from SP’s family saying she was not lost but instead scared off with a knife wielding man is 4:00, July 15.

Majority of media reports with SP’s family interview from the hospital bed declaring she was chased by a man with a knife where not until 6:00 news.
The spokeswoman's comment of the 22nd is of public speculation, imo.
On July 16th is the first LE statement of anything other than lost when the Inyo County Sheriff’s office releases what they term “Mrs. Powell’s recounting of event”.
