On Wednesday morning, the FBI's office in Phoenix, Arizona, issued a statement saying that they are conducting an "extensive search" of the Catalina Foothills near Nancy Guthrie's home just outside Tucson.

The search comes on the 11th day since the NBC's Today show host went missing on Sunday, January 31, from her home. The search comes amid a note received by the entertainment news outlet, TMZ. The sender demanded 1 Bitcoin (worth around $66,000, as of Wednesday) to be transferred to a wallet in exchange of information on the purported suspect.
“This morning, numerous FBI agents are conducting an extensive search along multiple roadways in the Catalina Foothills area related to the Nancy Guthrie investigation,” the FBI said.

But those links remain unconfirmed. As of now, authorities have not named a suspect, beyond the photos released.
However, later on Tuesday, one individual was taken into custody for questioning and was later released. So far, investigators have not been able to make any headway in the case.
