Nancy Guthrie update: Ransom kidnapping gone horribly wrong?

Over seven months have passed, and no sign of Nancy Guthrie has been found yet, and several theories have been floated.

This brings the latest one shared by former FBI agent Frank Storey.

Appearing on ex-FBI officer Jennifer Coffindaffer's YouTube channel, he believed the 84-year-old was kidnapped for ransom.

But after the abduction, something happened that the captors did not anticipate, according to Storey.

Nancy could have experienced a medical emergency that potentially led to her death, the former FBI agent theorized.

Meanwhile, since her disappearance from her home, Nancy Guthrie is still missing, and investigators are searching for her from all angles, including kidnapping.

Yet, seven months have passed, but no suspect has been arrested.

This prompts critics to question whether the investigation becomes a cold case.

However, ex-FBI agent Scott Augenbaum pushed back.

He told the local Tucson news station KOLD, “This is by no means a cold case.“

"A cold case is something that has been closed; it’s been put away," he continued.

"So in my opinion, this case is not closed at all. It’s still being held very tightly guarded by law enforcement, which I would expect at this point in time.”

But lately, the lack of public updates from the authorities gives the impression that the investigation into Nancy is going nowhere.

Augenbaum, however, explained that the lack of public announcements should not be taken to mean the police are abandoning the case.

By drawing on his own experience, Scott described two possibilities.

“There were cases where we didn’t really have any leads or anything like that, and we just played that close," he said.

But sometimes, the former FBI agent said, "There were situations where we kind of had a really amazing idea."

"We knew who did it, but we had to build the case against that person," Scott added.

As far as Nancy's case is concerned, the ex-FBI agent said her case “could be anywhere between those two things and somewhere in the middle.”

Recently, Savannah Guthrie's mom's disappearance marked seven months since she went missing from her home near Tucson, Arizona.
