- The FBI said the letters set a 5 p.m. Thursday deadline with a second deadline on Monday and announced a $50,000 reward for information leading to her recovery or an arrest.
- Savannah Guthrie and her siblings posted videos pleading for verifiable proof of life and direct contact, saying the family has received no direct communication.
- Investigators have identified no suspects or persons of interest; one person was arrested over a fake ransom demand as all leads continue to be evaluated.
- Officials stress urgency because the 84-year-old has limited mobility and needs daily medication, and they say they believe she is still alive.
