Advanced video equipment seen at Nancy Guthrie home as experts break down its possible role

TUCSON, Ariz. — A forensic tent that briefly covered the front porch of Nancy Guthrie’s home, where blood was previously found, has now been removed, but new questions are emerging about the high-tech equipment investigators were seen bringing inside.

Former NYPD homicide supervisor Joe Cardinale told Fox News Digital that the removal likely means investigators "finished what they were there to do" at that specific location.

Cardinale explained that tents are used to shield investigative activity from public view.
