Out front next, the breaking news, the sheriff and the Nancy Guthrie case tells CNN investigators have DNA evidence.

Unclear tonight, though, who it belongs to.

As the sheriff also confirms officials have several, quote, good leads.

Also breaking this hour, TMZ reporting it's received a third letter from someone who claims to know who kidnapped Nancy Guthrie.

TMZ's Harvey Levin is out front. And more breaking news, Don Lemon speaking out after pleading not guilty to federal charges. Let's go out front.

And good evening. I'm Erin Burnett on this Friday. And we begin with breaking news out front this evening, a major development in the Nancy Guthrie investigation.

The Pima County Sheriff confirming that investigators have DNA evidence. Now, the Sheriff is not saying exactly where that DNA is found, but they are calling it significant.

And the Sheriff is also telling CNN

that investigators have the DNA from Guthrie,

her family, her landskeepers, and her housekeepers,

okay? And they don't know who the DNA belongs to, right?

So obviously, you would presume they've run all those checks

and it wasn't this DNA.

And while there is still no indication of where Guthrie

could be, the sheriff did tell CNN, quote, we got some good leads. We remain hopeful.

So we're just chasing down leads. I've got 400 cops out there chasing down 30 some thousand leads.

And those 30 some thousand leads he refers to have been pouring in ever since authorities released the doorbell cam video which showed the masked

suspect outside guthrie's home the night she vanished now as for guthrie herself the sheriff

does say he believes she will be found.

And it all comes as we've got this new video tonight.

Okay, that's Nancy Guthrie's pool.

And those are maintenance workers at her pool today.
