The disappearance of Nancy Guthrie, an 84-year-old from her home in Arizona, has quickly escalated into one of the most followed criminal cases in the United States. Investigators believe that she may have fallen victim to kidnapping, prompting the involvement of the FBI, which has been searching for leads to uncover her whereabouts. Recent releases of surveillance footage have provided a more concrete lead in the ongoing mystery surrounding her case.

The footage, which was made public on Tuesday, captures a masked armed man attempting to tamper with the doorbell camera at Nancy's home on the night she vanished. This visual evidence marks a significant development in the investigation, as authorities from the Pima County Sheriff's Office are actively seeking to identify and locate this individual to further their inquiry. This point of interest intensified when it was reported that someone was detained the same day during a traffic stop in Rio Rico, south of Tucson, potentially related to the case.

In a turn of events during the investigation, CNN reported that the detained individual was released after claiming he had no knowledge of who Nancy Guthrie was and stating he worked as a courier. The case has captured the attention of the American public, raising questions about safety and the circumstances surrounding such disappearances, and continues to unfold as investigators pursue new leads, hoping for a breakthrough that could lead to Nancy's safe return.
