TUCSON, Ariz. (AP) \u2014 Savannah Guthrie<\/a> returned to hosting the \u201cToday\u201d show on Monday for the first time since her mother disappeared from her Arizona home more than two months ago.<\/p>\n Despite an intense search<\/a> involving thousands of law enforcement officers and volunteers, there has been no sign of the 84-year-old mother of three since she was reported missing Feb. 1. Her children, including the NBC host, have made heartbreaking video pleas<\/a> for help, but to no avail.<\/p>\n Here is a timeline of events:<\/p>\n 5:32 p.m. \u2014 Nancy Guthrie takes an Uber to her family\u2019s home for dinner.<\/p>\n 9:48 p.m. \u2014 Guthrie is dropped off at her Tucson-area 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\u2019s software detects movement. Investigators initially said there was no video available since Guthrie didn\u2019t have an active monitoring subscription. But digital forensics experts kept working to find images in backend software that might have 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 didn’t attend church. Moments later, they call 911 to report her missing.<\/p>\n 12:15 p.m. \u2014 Investigators arrive and launch a search operation, including the use of drones and dogs.<\/p>\n Authorities say 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. It includes a demand for money with a deadline set for 5 p.m. Thursday and a second one for Monday, investigators say.<\/p>\n A person familiar with the investigation tells The Associated Press that investigators found signs of forced entry<\/a> at Nancy Guthrie\u2019s home.<\/p>\n President Donald Trump tells reporters the situation is \u201cterrible.\u201d<\/p>\n After allowing Guthrie’s family back on her property earlier in the week, authorities return for a \u201cfollow-up investigation.\u201d<\/p>\n That evening, Savannah Guthrie posts video on social media<\/a> in which she tells her mother\u2019s kidnapper that her family is ready to talk but wants proof she is alive.<\/p>\n Officials reveal that DNA testing<\/a> determined that blood found on the home’s front porch was Nancy Guthrie’s.<\/p>\n The FBI offers a $50,000 reward for information about Guthrie\u2019s whereabouts.<\/p>\n Tucson TV station KOLD receives an email tied to the Guthrie case. The station didn’t disclose it’s contents and forwarded the message to federal investigators.<\/p>\n Investigators return to Guthrie\u2019s neighborhood to gather more evidence.<\/p>\n Savannah Guthrie post another social media video<\/a> aimed at her mother\u2019s potential abductors.<\/p>\n \u201cWe received your message, and we understand. We beg you now to return our mother to us so that we can celebrate with her,\u201d she said. \u201cThis is the only way we will have peace. This is very valuable to us, and we will pay.\u201d<\/p>\n Savannah Guthrie posts another video, saying her family is at an \u201chour of desperation\u201d and believes her mom is still alive. She asks for prayers and for people to report anything they might see or hear to law enforcement.<\/p>\n An FBI spokesperson says the agency was not aware of ongoing communication<\/a> between Nancy Guthrie\u2019s family and the possible kidnappers, despite a deadline set for Monday evening.<\/p>\n Later, in a March interview, Savannah Guthrie clarifies that some of the purported ransom notes were fake, but that she believes the two that she and her siblings responded to were real.<\/p>\n The FBI says it managed to recover doorbell camera video of what it describes as an armed person tampering with a camera at Nancy Guthrie\u2019s front door.<\/p>\n Video shows the person wearing a backpack and balaclava who tries to cover a camera near the front door with their gloved hand before ripping out a plant from the yard to block the camera\u2019s view.<\/p>\n Following the FBI\u2019s announcement, Savannah Guthrie posts images of the apparent kidnapper on Instagram. She writes: \u201cWe believe she is still alive. Bring her home,\u201d and includes phone numbers for the FBI and sheriff.<\/p>\n Later, the Pima County Sheriff\u2019s Department says a person was detained for questioning during a traffic stop south of Tucson. The man is released. He tells reporters that he made deliveries in the Tucson area.<\/p>\n The sheriff\u2019s department also says it searched a location in Rio Rico, a city south of Tucson, with the help of the FBI.<\/p>\n Authorities confirm that the man detained a day earlier was released but do not say what led them to stop him.<\/p>\n FBI agents and sheriff\u2019s deputies knock on doors and search the desert terrain<\/a> in the neighborhoods surrounding the homes of Nancy Guthrie and her oldest daughter, Annie Guthrie, whom she had visited hours before disappearing.<\/p>\nSaturday, Jan. 31<\/h2>\n
