Authorities have increased the reward for information in the disappearance of Nancy Guthrie, who they say was abducted from her home outside Tucson. Law enforcement officials have been combing the desert around her house and going door-to-door asking residents for any information that could break open the case. An alert that went out in a 2-mile (3.2-kilometer) radius of her home asked for any camera footage or reports of suspicious activity over a month’s time.


Guthrie was last seen on January 31 and reported missing the following day. Authorities released a description of a man caught on camera outside her front door the night she disappeared and a description of the backpack he was wearing.


Her children have made heartbreaking video pleas for help, and the case has drawn national attention.


Here is a timeline of events:


Saturday, January 31


5:32 p.m. — Nancy Guthrie takes an Uber to her family’s home for dinner.


9:48 p.m. — Guthrie is dropped off at her Tucson, Arizona, home by a family member. The garage door opens and closes minutes later.


Sunday, February 1


1:47 a.m. — The doorbell camera is disconnected.


2:12 a.m. — 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 continued to work to recover images from backend software that might have been lost, corrupted, or inaccessible.


2:28 a.m. — Her pacemaker app disconnects from her phone.


11:56 a.m. — Her family checks on her after learning she did not attend church.


12:03 p.m. — The family calls 911 to report a missing person. Investigators arrive and launch a search operation, including the use of drones and search dogs.


6:46 p.m. — The Pima County Sheriff’s Department posts on social media to announce Guthrie’s disappearance.


Monday, February 2


Authorities announce in the morning that they believe Guthrie was kidnapped or taken against her will.


KOLD-TV says it received an email reportedly tied to a ransom note. The note includes a demand for money with set deadlines for payment.


Subsequent days saw various investigations, including a confirmation of forced entry into Guthrie's home and the recovering of crucial video evidence that showed suspicious activity around her door.


As the search intensifies, donations and community support grow, with a rising number of volunteers aiding in the investigative efforts.
