This is the only way we will have peace.” She added: “We will pay.”

• Purported deadline nears: Guthrie’s possible abductors are demanding $6 million by 5 p.m. today, CNN affiliate KGUN reported, citing a purported ransom note sent to the station. The note included a threat to Guthrie’s life if the deadline isn’t met, according to KGUN.

Supporters leave flowers outside Nancy Guthrie’s home

Supporters left flowers outside Nancy Guthrie’s home in Tuscon, as the search for the 84-year-old enters its ninth day.

The flowers were placed near other tokens of support, including candles and religious symbols, surrounding a sign reading, “Dear Guthrie Family, Your neighbors stand with you.”

Flowers and candles are seen alongside a sign outside of Nancy Guthrie's home in Tucson, Arizona, on Monday.

The evidence linked to Guthrie’s disappearance

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.
