Law enforcement searched Annie Guthrie’s Arizona home on Feb. 7 as part of the ongoing investigation into her mother Nancy Guthrie’s disappearance and possible ransom.

The search came hours after Annie and her siblings shared a video message appealing to Nancy’s potential kidnapper.

Authorities are also investigating an alleged ransom note that set a second deadline for Feb. 9.

No suspects or persons of interest have been identified, and officials continue to follow multiple leads, including probing Nancy’s home for evidence, People has reported.

Nancy, 84, was last seen on Jan. 31, and investigators believe she was taken against her will.
