Overview
- The FBI is offering $100,000 and has released photos and video of a masked person approaching the Tucson home the night Nancy Guthrie vanished.
- Investigators report the doorbell camera was disconnected around 1:47 a.m., a presence was detected at 2:12 a.m. without video, and DNA testing found her blood on the porch.
- Officials say the 84-year-old has reduced mobility, making it unlikely she left on her own, and they have not identified or charged any suspect.
- Authorities are examining alleged ransom letters received by media organizations, whose authenticity remains unconfirmed.
- A man detained earlier in the probe was released, family involvement has been discounted by the sheriff, and tip lines have logged thousands of calls.
