REVEALED: Why man was arrested for driving up and down Nancy Guthrie’s street 100 TIMES with picture of Savannah’s kidnapped mother

The man who was allegedly caught driving past Nancy Guthrie‘s home ‘100 times’ was arrested on DUI charges, authorities revealed.

Antonio De Jesus Pena-Campos, 34, was nabbed by officers with the Pima County Sheriff’s Department on Thursday evening after reporters spotted him driving a blue Chevy SUV ‘very slowly’ near her Tucson home, police said.

After officers arrived at the scene, they conducted a sobriety test on Pena-Campos that he failed.

He was then handcuffed and placed into a sheriff’s cruiser. His arrest is not related to the disappearance of Savannah Guthrie’s mother, authorities stated.

Footage obtained by Fox News showed deputies shining a flashlight into the car before Pena-Campos exited the vehicle and was seen talking to officers near a large white tent. 

He was then seen trying to walk in a straight line during his sobriety test and following a small flashlight with his eyes.

Before police confirmed Pena-Campos’s arrest and identity, NewsNation correspondent Brian Entin reported that the driver ‘just kept stopping’ outside the property, passing between ’50 and 100 times.’

A media photographer who approached the individual reportedly also noticed he had a photo of Nancy on his phone.

Nancy, 84, has been missing for nearly four weeks. Savannah Guthrie’s mom was last seen on January 31 after dinner and a game night at her eldest daughter’s home

‘It is weird. There’s some just like creepy people that come by,’ Entin said. 

The bizarre incident comes as the search for Nancy nears its fourth week. 

The mother of three was last seen on January 31, after being dropped off by her son-in-law, Tommaso Cioni, following a dinner and game night at her eldest daughter Annie’s home. 

She was reported missing the following morning after she didn’t show up for a church service. 

Footage recovered from her Nest doorbell camera showed an unidentified suspect in a ski mask in front of her door early on February 1, before Nancy’s pacemaker suddenly stopped transmitting data to her iPhone and Apple Watch

Authorities, including the sheriff’s office and the FBI, have been on the case ever since, but the few leads they have received have led nowhere, as Nancy’s whereabouts still remain unknown. 

Savannah, Annie and their brother Camron have shared several emotional videos online pleading for their mother’s captor to come forward and bring her home

On Tuesday, Savannah acknowledged for the first time that Nancy might not be alive.

‘We need to know where she is, we need her to come home,’ she said in a video posted to her Instagram account.

‘We also know that she may be lost, she may already be gone. She may have already gone home to the Lord that she loves,’ Savannah said through tears.

She posted a series of videos on Friday explaining how tipsters can collect the new $1 million reward her family is offering for information leading to the safe return of her mother. 

The 54-year-old reposted her original plea from Tuesday and shared a Today Show report explaining how to submit anonymous tips to the FBI, overseen by co-anchors Carson Daly, Hoda Kotb and Craig Melvin.

‘Please – be the one that brings her home,’ Guthrie wrote in a caption. ‘Tips can be anonymous, reward can be paid in cash, as explained here.’ 

The Federal Bureau of Investigation (FBI) recently announced that the agency would be scaling back its almost month-long search for Nancy, with agents moving to a new command post more than 100 miles away from Phoenix, sources with knowledge of the investigation told ABC News.

Some agents will also stay behind in Tucson, they said. Agents in Phoenix, meanwhile, will work the case from there.

The move does not indicate investigators are giving up on the search, the sources claimed.

Agents were seen outside the residence on Wednesday, combing through portions of the home and lawn that had already been searched.

The flurry of activity was related to an FBI effort to turn the home back over to the Guthrie family, officials told NBC News.
