The evidence linked to Guthrie’s disappearance

From CNN’s Catherine Nicholls

In the nine days since Nancy Guthrie’s disappearance, authorities have released information about some of the potential evidence being looked at in their investigation.

Take a look at what we know about this evidence below:

  • A surveillance camera at the 84-year-old’s house detected a “person on camera” at 2:12 a.m. on Sunday, February 1, but there was no video to show who — or what — exactly triggered the alert, officials said. Because of this, it is possible that the camera was not triggered by a person, but instead something else, like an animal, Pima County Sheriff Chris Nanos said Thursday.
  • Blood found on the front porch of Guthrie’s home belonged to her, Nanos also said last Thursday. Video taken by channels KTVK and KPHO showed what appeared to be blood on the property’s front door, as well as on the porch tiles.
  • A front-door camera is missing from Guthrie’s home, Nanos told CNN. The camera was previously in the “front door area” of the house, and investigators are not aware of any other cameras missing, Nanos said.
  • Guthrie had a pacemaker that was connected to her iPhone, according to a source briefed on the investigation. Nanos said Guthrie’s pacemaker app data shows it disconnected from her phone at 2:28 a.m. on Sunday, February 1.
  • Two purported ransom notes have been sent to media outlets since Guthrie’s disappearance. The first demanded millions of dollars in bitcoin for Guthrie’s return, with two deadlines – the first being last Thursday and a second deadline of today, FBI Special Agent in Charge Heith Janke said.
