Experts Screening Tips In Nancy Gutherie Disappearance

More than 4,000 calls came into an Arizona sheriff’s department within 24 hours after the release of videos of a masked person on Nancy Guthrie’s porch. Many will be worthless. Others could have merit. Experts say one thing’s certain: The tips can’t be ignored. Images of a mysterious person have been the most significant clues shared with the public during Guthrie’s disappearance in the Tucson area. She is the mother of NBC “Today” co-anchor Savannah Guthrie. Roberto Villaseñor, a former Tucson police chief, says processing tips is a tremendous amount of work. The FBI says it has collected more than 13,000 tips since Feb. 1., and the sheriff’s office says it’s received at least 18,000.
