That is Fox's Matt Finn.

We are still trying to piece together exactly what resulted from all this heavy police activity last night.

Our crews saw a SWAT team and a lot of officers only about a mile and a half, two miles from where I'm standing outside of Nancy's home.

And there are

You know, reports of people possibly being questioned or apprehended by police.

But the lead agencies, the Pima County Sheriff's Office and the FBI, have not confirmed if anybody was taken into custody.

Now, the Pima County Sheriff confirms that some of its activity was in relation to the Nancy Guthrie case.

Writing, law enforcement activity is underway at a residence near East Orange Grove Road and North First Avenue related to the Guthrie case.

Because this is a joint investigation at the request of the FBI, no additional information is currently available.

County Sheriff is asking anyone with a camera in roughly a two-mile radius of Nancy's home to check their video from January 1st through February 1st and submit any video to the Pima County Sheriff's online link.

They're looking for people, cars, or of course, suspicious activity.

Reward for the information leading to an arrest has been increased to $100,000.

The suspect is also believed to be carrying a backpack called an Ozark Trail Hiker Backpack.

The FBI believes that is what he was carrying that night.

As of this morning, there are no known suspects.

Law enforcement is not asking the public to be on the lookout for anyone in particular, and that includes a vehicle.
