New surveillance video<\/a> of a masked and apparently armed person on Nancy Guthrie\u2019s doorstep the night she went missing was released Tuesday by federal investigators.<\/p>\n It’s the first major break in the intensifying search for the 84-year-old mother<\/a> of \u201cToday\u201d show host Savannah Guthrie<\/a>. Authorities have not identified any suspects or persons of interest and are seeking help identifying the person in the video. It’s been more than a week since investigators believe Nancy Guthrie was abducted from her home in Arizona.<\/p>\n Her children have made heartbreaking video pleas<\/a> for help and the case has drawn national attention<\/a>. Two deadlines in purported ransom notes sent to the media have come and gone, but it’s unclear of there’s been any contact with the abductors or if Nancy Guthrie is still alive.<\/p>\n Here is a timeline of events:<\/p>\n 5:32 p.m. \u2014 Nancy Guthrie takes an Uber to her family’s home for dinner.<\/p>\n 9:48 p.m. \u2014 Guthrie is dropped off at her Tucson, Arizona, home by a family member. The garage door opens and closes minutes later.<\/p>\n 1:47 a.m. \u2014 The doorbell camera is disconnected.<\/p>\n 2:12 a.m. \u2014 The camera’s software detects movement. Investigators initially said that there was no video available since Guthrie didn’t have an active subscription to the company. But digital forensics experts kept working to find images in backend software that might’ve been lost, corrupted or inaccessible.<\/p>\n 2:28 a.m. \u2014 Her pacemaker app disconnects from her phone.<\/p>\n 11:56 a.m. \u2014 Her family checks on her after learning she did not attend church.<\/p>\n 12:03 p.m. \u2014 The family calls 911 to report a missing person.<\/p>\n 12:15 p.m. \u2014 Investigators arrive and launch a search operation, including the use of drones and search dogs.<\/p>\n 6:46 p.m. \u2014 The Pima County Sheriff\u2019s Department posts on social media to announce Guthrie\u2019s disappearance.<\/p>\n Authorities announce in the morning that they believe Guthrie was kidnapped, abducted or otherwise taken against her will<\/a>.<\/p>\n KOLD-TV says it received an email Monday night that appears to be a ransom note. The note includes a demand for money with a deadline set for 5 p.m. Thursday and a second one for Monday, investigators said.<\/p>\n Savannah Guthrie posts a message on Instagram on Monday night asking for people’s prayers.<\/p>\n A person familiar with the investigation tells The Associated Press that investigators found signs of forced entry<\/a> at Nancy Guthrie’s home.<\/p>\n President Donald Trump tells reporters that the situation is \u201cterrible.\u201d<\/p>\n After turning back Guthrie’s property to her family earlier in the week, authorities return to the home for a \u201cfollow-up investigation.\u201d<\/p>\n That evening, Savannah Guthrie posts a video on social media<\/a> in which she tells her mother\u2019s kidnapper that her family is ready to talk but wants proof their mom is alive.<\/p>\n Officials reveal that a DNA<\/a> test of blood found on the home\u2019s front porch showed it came from Nancy Guthrie.<\/p>\n The FBI offers a $50,000 reward for information about Guthrie\u2019s whereabouts.<\/p>\n Tucson TV station KOLD receives a new message, via email, tied to the Guthrie case. The station says it can’t disclose its contents. The FBI says it’s aware of a new message and is reviewing its authenticity.<\/p>\n Investigators return to Guthrie\u2019s neighborhood to gather more evidence. The president of the Catalina Foothills Association, a neighborhood group, thanks residents in a letter for being willing to speak with law enforcement, share camera images and allow their properties to be searched.<\/p>\nSaturday, Jan. 31<\/h2>\n
