Savannah Guthrie issued a new plea for information on Saturday, after authorities released two ransom received in the days after her mother Nancy’s disappearance six months ago.

Guthrie wrote on Instagram, “We are begging for help. We are desperate. We need someone to come forward. Someone knows something. Someone suspects something. Someone recognizes the writing in the ransom demand notes. Someone has noticed something different, strange, troubling or just unusual – perhaps with someone they deeply love. Perhaps they are afraid to come forward. Perhaps they are conflicted. Perhaps they are angry or upset for being in this situation. There is a way out – to tell what you know. You can do so anonymously. The reward is available. There is a way to end this situation and do the right thing.”

The Today co-host added, “We are real people, facing real grief, doing the best we can, and counting our many blessings along the way – most especially the prayers and love from good people, which we feel deeply. We need your prayers, we need your kindness. We need the good to be stronger than the evil. If you are following this story for entertainment or for profit, you are not on her side – you are part of the harm perpetrated against her.”

Nancy Guthrie was last seen on Jan. 31, after she was dropped off at her Tucson area home.

On Friday, the Pima County Sheriff released two ransom notes allegedly sent by her kidnappers, an effort to generate new leads in the case.

The first note, sent to Tucson news outlet KOLD-TV a day after her disappearance, was addressed to Savannah Guthrie, and said that she was “safe but scared” and would not be released until payment, $4 million in bitcoin, is received, according to the full messages released by the Pima County Sheriff’s Department and the FBI Phoenix Field Office. The note said that she would be released for a maximum of seven days.

The second note, sent Feb. 6, also to KOLD, stated that Guthrie died shortly after she was taken.

The note read, “We did not fully grasp the seriousness of her physical condition. We never intended to hurt her, that was not our intention. She perished shortly after she was taken. We believe it was heart related. She is buried in nature now. Nothing you could have done could have changed the outcome. We want your family to know this and hope you all can find peace. We are truly sorry.”

Anyone with information is urged to contact 1-800-CALL-FBI (1-800-225-5324). The Guthrie family is also offering a $1 million reward for the return of their mother.
