Good evening and welcome to a special edition of Laura Coates Live, the search for Nancy Guthrie.

Tonight we've got the clearest description yet of who investigators are trying to find.

The FBI is putting out new information about the person

they're now officially calling a suspect.

The same masked person who was captured on camera

outside Nancy Guthrie's home 12 nights ago.

And that reward for his arrest, well, it just doubled.

In just a moment, our reporters and law enforcement

will join me to break it all down.

Here the FBI is saying, though, the suspect is a man. He's about 5-9 or 5-10. He has an average

build, and this is key. He was wearing a black 25-liter Ozark Trail Hiker pack.

Now, here's a side-by-side comparison of that backpack next to images of the suspect.

They have reflectors on the straps.

Suspect's bag was also completely packed.

And you know what? Just for scale, I was curious.

I got an actual version of that backpack.

Here it is obviously empty, but just so you know the capacity

that it could possibly, possibly carry, quite expansive. We have no idea what actually was inside

the backpack, but it is readily available. Will that complicate the investigation?

The FBI is also up their reward from $50,000 to $100,000. Law enforcement is

working with a flood of tips. More than 13,000 have been submitted to the FBI alone just

since February 1st. And they're hoping they may get some critical tips of people living within
