The Pima County Sheriff’s Office is set to give an update on Savannah Guthrie‘s missing mother, Nancy … and, we’re carrying the press conference live for you to watch.

Sheriff Chris Nanos will lead the media briefing about the 84-year-old who was last seen Saturday night at her Tucson, Arizona home.

Authorities have already said they saw concerning signs at Nancy’s house after she was reported missing Sunday … including finding Nancy’s DNA inside and the front door kicked in. The L.A. Times reported it was her blood that was found in the house.

Ultimately, the sheriff’s office labeled Nancy’s disappearance an abduction … and put homicide detectives on the case. Authorities have made it clear they’re in a race against time to find Nancy — because she’s without meds she needs to survive.

Investigators have been looking at registered sex offenders and others in the area while combing through video from cameras at her home, neighbors’ residences, local businesses, and traffic lights.

Savannah’s been absent from “TODAY” amid her mom’s abduction … though she did thank her fans for their thoughts and prayers during this difficult time.
