Police Arrest Man After Concerning Behavior in Front of Guthrie Home

Police arrested a man exhibiting concerning behavior in front of the memorial built to Guthrie near her home, according to a report from NewsNation.

The man exhibited “weird” behavior was apprehended by police after the media spotted him slowly driving past Guthrie’s home in Tucson in a blue vehicle and repeatedly stopping to look at a memorial set up outside. According to the New York Post, the man allegedly drove by Guthrie's home up to 100 times while looking at a photo of the missing grandmother on his phone.

Arrest Comes After Neighbor Admitted Seeing 'Suspicious' Man

The arrest comes just two days after one of Guthrie's neighbors, Aldine Meister, revealed she saw a “suspicious” man that “didn’t fit” while walking through the neighborhood.

“He didn’t have your typical walking gear on, and he had his hat pulled really far over his eyes,” Aldine Meister told Fox News Digital. “…He was kind of younger, and he just didn’t look like he was going out for a walk.”

Meister revealed she'd never seen the younger man before and didn’t initially report the suspicious man to authorities. However, following Guthrie’s disappearance, she told police about the man she had seen, though she didn’t have video of the encounter.

FBI Moves Command Center

Following a final sweep of the Guthrie residence, the FBI reportedly turned the home back over to the Guthrie family. Not long later, a report emerged revealing the FBI is moving its command center from Tucson to Phoenix.

"The transition is being done because the large Phoenix command post will be able to operate more efficiently for the long term, and most of the agents who have been working on the investigation in Tucson are based in Phoenix," per CBS News.

The Pima County Sheriff's Department nor the FBI have issued a statement following the latest arrest in front of he Guthrie home as of Friday morning.
