Authorities have searched the home of Annie Guthrie amid the ongoing search for her mother, Nancy Guthrie, who is being held for ransom.

As the search for Nancy, 84, continues, law enforcement officials were seen at the residence of Annie and her husband, Tommaso Cioni, late in the evening of Saturday, Feb. 7, just hours after Annie and siblings Savannah and Camron Guthrie shared a new video message for their mom’s potential kidnapper.

Annie’s property is located approximately four miles from her mother’s longtime home in Tucson, where she was taken in the middle of the night on Jan. 31, authorities said.

Tracy Walder, a former CIA and FBI special agent, tells PEOPLE that ahead of searching Annie and Cioni’s property, law enforcement officials “may have either asked Annie’s permission,” obtained a search warrant or both.

Authorities, including at least one official with the Pima County Sheriff’s Department (PCSD), searched Annie’s home from about 8 p.m. to 10:30 p.m. local time. After over two and a half hours, one official was seen exiting the home while carrying a white suitcase and brown bag. Another was seen wearing blue gloves.

“All that white case is — is evidence processing tools. The brown bag is for evidence,” Walder tells PEOPLE of the scene at Annie’s home.

“The back and forth is of course odd and we don’t see that a lot,” she adds of the searching parties’ behavior, which she says could be attributed to “so many things” such as “reactions to ransom note details, new suspects emerging, request by the family, etc.”

On Sunday, Feb. 8, authorities, including PCSD deputies and vehicles, were also seen at Nancy’s home. Officials used a pole to probe a manhole located on the property, behind the house, according to drone-captured images shared by Fox News’ Sarah Rumpf-Whitten on X.

There are currently no suspects or persons of interest in the investigation into Nancy’s disappearance, the PCSD said in the latest update, shared on the morning of Feb. 8.

“The Nancy Guthrie investigation is ongoing,” the department wrote. “Follow-up continues at multiple locations. No suspects, persons of interest, or vehicles have been identified. No scheduled press briefings.”
