Investigators shared a more precise timeline Thursday showing that they believe Nancy Guthrie, 84, was taken from her Tucson home in the early hours of Sunday, Feb. 1.
Guthrie took an Uber ride at 5:32 p.m. Saturday to go to a family member's home for dinner. A family member brought her back home at 9:48 p.m. Her home's garage door was closed at 9:50 p.m.
At 1:47 a.m. the home's doorbell camera was disconnected. Nanos said that doorbell camera is not in the Sheriff's Department's possession.
At 2:12 a.m., "software detects a person on a camera," but no video is available because Guthrie did not have a subscription to the surveillance service, Nanos said.
At 2:28 a.m., Guthrie's pacemaker disconnected from her cellphone, he said.
Guthrie's family checked on Nancy at 11:56 a.m. after learning from her church that she did not attend services.
At 12:03 p.m. Sunday, the family called 9-1-1 to report her missing. Deputies arrived at 12:15, Nanos said.
Investigators have searched cameras from nearby neighbors and businesses, while deputies checked with local hospitals hourly following Guthrie's disappearance, Nanos said.
Authorities know what medication Guthrie needs, Nanos said, which he has stressed repeatedly throughout the week. Without it, Nanos has said, Guthrie's survival is in peril. Given the dire need for her medication, Nanos said investigators contacted local pharmacies early on in their search, and will probably do so again.
