Thomas’ husband told KTNV that they took their trailer to the desert for the weekend. They were close to the RV when Robert stopped to take a picture.
“By the time I took the picture she was continuing on because she wanted to get to the RV,” he said. “And she rounded the corner and I lost sight of her.”
He suspects something happened when she crossed a highway. “My feeling is that she was picked up because she had to cross a highway. She was wearing a bikini and she had a beer in her hand.”
He said she may be in the Las Vegas area.
