Tonight on 360, investigators release new details about the man in this video outside Nancy Guthrie's door the night she was taken from her home.

Detail number one, the person is in fact a man. They're also focusing their search and doubling their war for information.

Also tonight, might a single small clue crack the case? I'll show you when it has in some of the country's

most notorious crimes. And later after putting 3,000 armed mass federal agents on the ground in

Minnesota, killing two U.S. citizens at point-blank range, the Trump administration says mission

accomplished and is bringing its operation there to a close. We'll talk to Minnesota Senator Amy Klobuchar.

Good evening, thanks for joining us.

We begin tonight with more new developments and investigators hope will bring them closer

to finding Nancy Guthrie and catching whoever took her.

Or jogs someone's memory enough to recognize the man in this doorbell video from the night

she was taken.

Now late today, the FBI revealed what their analysis of the footage tells them about him.

The man is approximately 5'9 or 5 foot 10, they say, average build.

They have also identified the backpack he's wearing, a black 25-liter-sized Ozark Trail Hiker

pack.

No identification yet, though, of the gun in the holster at his waist.

However, just moments ago, we learned the significance of the white tent, which went up briefly outside

Ms. Guthrie's front door earlier today. A law enforcement source telling CNN it was to simulate

nighttime conditions to help FBI specialists identify the backpack and the clothing the man in the video was wearing.

Now the FBI adds that they've now received more than 13,000 tips since the search began on the first of this month.

And in a sign, they want more. They doubled the reward today for information leading to her recovery to $100,000.

Investigators are also asking Ms. Guthrie's neighbors to check video from their own surveillance cameras from two specific days in January, the 11th, and the 31st.
