“We believe our mom is still out there,” Guthrie said in a video shared on her Instagram account Monday afternoon. “She was taken, and we don’t know where.”

Savannah asked for anyone to across the country to report any suspicious activity they witness.

“I’m coming on just to ask you not just for your prayers, but no matter where you are — even if you’re far from Tucson — if you see anything, if you hear anything, if there’s anything at all that seems strange to you, that you report to law enforcement,” she said.

“We need your help,” she added.

Savannah and her siblings had previously agreed to pay in a video shared on Saturday (February 7).

“We received your message and we understand,” Savannah said, while holding hands with her brother, Camron, and sister, Annie in the video shared to her Instagram account. “We beg you now to return our mother to us so that we can celebrate with her. This is the only way we will have peace.”

“This is very valuable to us, and we will pay,” she concluded.
