Sheriff says 18,000 tips have come in on Nancy Guthrie case

The Pima County Sheriff’s Department and the FBI said on Wednesday they are continuing to follow up on all 18,000 calls to investigators related to the disappearance of Nancy Guthrie.

Up to 4,000 calls to investigators have been made since the FBI released doorbell-camera images and video of an “armed individual” apparently tampering with a security camera at the front door of the 84-year-old woman’s house near Tucson, Arizona, authorities said.

“We thank the media and the public for the thousands of tips submitted through the various tip lines,” the sheriff’s office and the FBI said in a joint statement.

Several hundred detectives and agents are assigned to this case, and authorities said, “You will continue to see increased law enforcement activity throughout Pima County as the investigation expands.”
