Savannah Guthrie, in an emotional Instagram post Tuesday morning, said her family is offering a reward of up to $1 million for “any information” that would lead to the recovery of her missing mother, Nancy Guthrie, who vanished from her Arizona home after last being seen entering it the night of Jan. 31.

“Help us bring our beloved mother home,” Savannah Guthrie, a co-anchor of NBC’s “Today Show,” said in the video post.

“Please be the light in the dark,” she said.

Guthrie acknowledged her 84-year-old mother, who is believed to have been abducted, may not be alive given the time that has passed, her age, and her medical issues.

“She may already be gone,” Guthrie said.
