The Arizona community should expect “a lot of police activity” every day, Pima County Sheriff Chris Nanos said – as the search for Nancy Guthrie enters its 14th day.

“Everyday moving forward there will be a lot of police activity throughout the community. As to what level of activity that is depends on what lead they chase and how it develops,” Nanos told Fox News Saturday.

“These leads start in the command post and move to the field as needed. That is one reason you’re seeing activity build up as the day goes on that can ultimately lead to a search warrant looking for Nancy and any suspect involved,” he said.

News of the increased police presence comes after at least three people were taken into custody in two separate investigations late Friday — including swarming a local Tucson property.

All the people detained were released after being interviewed by authorities.

David Curl, a retired lawyer, lives next to the house investigators spent hours searching and took in the resident, an older woman who lives there with her son, he said.

The woman — who was at home by herself when investigators arrived at around 6 p.m. Friday night with a search warrant — was not allowed insideas it was being searched, so she spent the night at his house, Curl said in an interview with the New York Times Saturday.

Investigators left the property early Saturday. A copy of a federal search warrant mentioning the Guthrie case was found in the living room when he went back to the house with his neighbor to lock up, Curl told the outlet.

“She had no idea what they were asking about,” Curl said of his neighbor. “She had no information about the disappearance or any idea why they were focusing on their house…she’s really distraught.”

Curl said his neighbor’s son had been questioned by authorities, and was later released — though it remains unclear how the search is connected to Nancy’s disappearance.

Nanos told Fox News he was not present at the residence that was searched — and guessed anyone at the property was “detained,” which is standard protocol “to allow investigators serving a search warrant freedom to conduct their search.”

“I was not at the scene and I’m sure people were detained but no one was arrested and more importantly…no sign of Nancy was found,” Nanos said.

Despite law enforcement officials receiving more than 32,000 leads since Nancy disappeared from her Tucson home Jan. 31, no arrests have been made.
