Retired FBI agent Jennifer Coffindaffer said on 15 March that the Nancy Guthrie investigation needs a sharper public appeal, arguing the FBI should feature the masked man seen outside the missing 84 year old's Tucson home on its billboards rather than relying on Nancy Guthrie's image alone. Her intervention landed weeks after federal authorities began placing billboards in Arizona, Texas, New Mexico and California as the search for Savannah Guthrie's mother stretched into its sixth week.
Nancy Guthrie was last seen on the evening of 31 January after dinner with family and was later dropped back at her Catalina Foothills home shortly before 10 pm, according to the reported timeline of events in the case. Investigators have treated the disappearance as a targeted kidnapping, and blood found on the front porch was identified as hers, which gives the story a grim edge that no amount of billboard design can soften.
