The search for Nancy Guthrie’s kidnapper is being investigated in a new way.

Search for what you’re looking for Nancy GuthrieWe’re looking at kidnappers in a new light… It’s not about tips or what we know. The kidnapper is visible on camera. …It’s important to find someone who fits that description – someone who’s been missing for three weeks.

A law enforcement source involved in the investigation told TMZ. We especially want people in the Tucson area to think about who has been MIA in the past three weeks, and we now have a significant amount of information that could help identify the kidnapper.

The man is between 5 feet 9 inches and 5 feet 10 inches tall, has an average build and facial hair (moustache or beard). If the ransom letter TMZ received is real, he’s a smart, tech-savvy guy. Authorities believe he lives in the Tucson area.

The kidnapper had an Ozark Trail Hiker backpack, a coat believed to be an Athletic Works Fusion Knit jacket, a polyester holster, and a semi-automatic handgun.

Nancy reported missing February 1st… So the assumption here is that the kidnapper hasn’t been seen in public since then.
