FBI agents and Swat teams swarmed a property just two miles from Nancy Guthrie's residence as part of an investigation into the 84-year-old's disappearance.
Three individuals were taken into custody during the operation, with one person reportedly shooting himself, according to local news reports.
The tactical teams descended on the Tucson, Arizona home at approximately 9pm local time on Friday, acting on a tip received by investigators.
Pima County Sheriff's Department confirmed the FBI's involvement in the joint investigation but declined to release further details at the bureau's request.
