Authorities in Arizona’s Pima County are expected to hold a news conference with the latest on the investigation into the disappearance of Savannah Guthrie’s mother, Nancy.

Watch it live in the player above when it begins around 1:30 p.m. ET.

Earlier in the day, authorities with the sheriff’s department confirmed that DNA samples collected from the home belong to Nancy Guthrie. Investigators wouldn’t say if those samples contained blood.

Authorities say they are withholding specific details about evidence to protect the integrity of the investigation.

The planned announcement comes a day after Sheriff Chris Nanos said investigators are treating Nancy Guthrie’s case as a possible abduction. They say she did not appear to leave her home voluntarily.

Nancy Guthrie, 84, was reported missing around noon on Sunday. She had last been seen the night before.

Savannah Guthrie asks people to ‘pray’

Savannah Guthrie, who was absent from the “TODAY” show on Monday and Tuesday, expressed her gratitude for the support in a Monday night Instagram post — and asked for prayers for her mom’s safe return.

“We believe in prayer. We believe in voices raised in unison, in love, in hope. We believe in goodness. We believe in humanity. Above all, we believe in Him,” Guthrie wrote in a caption to a photo that reads “please pray.”

“Thank you for lifting your prayers with ours for our beloved mom, our dearest Nancy, a woman of deep conviction, a good and faithful servant. Raise your prayers with us and believe with us that she will be lifted by them in this very moment,” she added. “We need you.”

Authorities in Arizona are searching for the 84-year-old mother of “TODAY” host Savannah Guthrie, who was reported missing over the weekend.
