Harrowing surveillance video and photos have been released by the FBI of an armed person in a ski mask tampering with Nancy Guthrie’s home’s security camera the morning she vanished. The images were “recovered from residual data located in backend systems,” FBI Director Kash Patel wrote. The release Tuesday was the first time law enforcement had released anything having to do with a possible subject since the 84-year-old vanished 10 days ago – and the first indication that police were zeroing in on any suspects at all after a gruelingly fruitless investigation.
