Authorities investigating the case of Savannah Guthrie’s mother, Nancy, conducted a search of a septic tank located behind her residence on Sunday. Drone footage captured them as they opened a manhole cover in the backyard.

Three detectives were pictured inserting a long pole into the manhole situated behind the house. However, no additional details have been disclosed regarding their search objectives, according to NY POST.
The investigators departed without any findings. The reasons behind their decision to inspect the septic tank remain unclear.
This development comes as law enforcement reiterated that they have not identified any suspects or persons of interest in this case.
The 84-year-old woman was last seen more than a week ago after being dropped off at her Tucson home by her daughter Annie Guthrie and son-in-law, Tommaso Cioni.

“So, somebody may have flushed something thinking that would get rid of it, but instead it would actually just be deposited in the septic tank. It is a possibility that [investigators] are now trying to make sure that there’s nothing in there that could indicate any kind of guilt,” he added.
