Nancy Guthrie’s possible abductors are demanding $6 million by 5 p.m. today, CNN affiliate KGUN reported, citing a purported ransom note sent to the station.

Nancy Guthrie, mother of "Today" show co-host Savannah Guthrie, has been missing from her Tucson-area home for six days.

The Guthrie siblings post a video on Instagram with Savannah Guthrie saying they “need to know without a doubt that she’s alive and that you have her.”
