Savannah Guthrie announced on Instagram that her family is offering up to $1 million for information leading to the recovery of her mother, Nancy Guthrie, who disappeared from her Arizona home on Jan. 31.

Guthrie, co-anchor of Today Show, said her 84-year-old mother may have been abducted and acknowledged she may no longer be alive due to her age and medical conditions.

The Pima County Sheriff’s Office is investigating the case as a possible kidnapping.

In her emotional post, Savannah pleaded with anyone who has information to come forward, saying, “Please be the light in the dark,” CNBC has reported.

The FBI also maintains a $100,000 reward in addition to the family’s $1 million offer.
