The Arizona man who was briefly detained in the Nancy Guthrie investigation is firing back at all the cops involved ... insisting the whole thing felt like a "fishing expedition" to pressure him into confessing to something he says he didn’t do.

In a sit-down interview on "True Crime Arizona" Monday, Luke Daley recalled cops pulling him over, cuffing him without explanation and detaining him for hours ... admitting the mounting pressure on law enforcement to solve the case had him panicking about being "framed."

Luke insisted time and time again that despite living nearby to Nancy, he had never met her and had absolutely nothing to do with her disappearance ... and wants her home safe just like everyone else.

12:52 PM PT -- Savannah Guthrie posted a still shot of the memorial scene on her Instagram Story just now … showing bright flowers against the greenery and blue sky in the background, writing how she and her family are feeling the love and prayers from well-wishers everywhere, adding … "please don't stop praying and hoping with us. bring her home."

Savannah Guthrie and family members were filmed outside their mother Nancy's Tucson, Arizona home this morning ... taking in a growing memorial for their mom one month into her search.

Watch the clip ... Savannah, her sister Annie, and brother-in-law Tommaso embraced as they laid flowers for Nancy. The memorial consisted of many bouquets and also signs with loving messages, along with what appears to be Nancy's "Missing" poster.

An attorney for two people targeted in raids connected to Nancy Guthrie's disappearance is calling out law enforcement for going after his client ... who he says has no involvement in the crime.

Attorney Chris Scileppi represents Luke Daley -- the Arizona man who was the subject of two search warrants issued and served a couple weeks ago in connection to the Guthrie case -- and, he tells TMZ he's absolutely sure his client has no link to Nancy.

Daley and his mother were offended about being detained, Scileppi says ... and their homes and vehicles were significantly damaged during the search.

Savannah Guthrie has not indicated she's made a decision about whether or not she will return to "Today," TMZ has learned.

Our insiders say her return -- or departure -- from the morning news program is still an open question ... and there is no timeline for if or when she is coming back. We're told NBC is being cautious not to pressure her.

Meanwhile, sources at NBC tell us the show is "fully supportive" of a potential return, adding ... "It’s just a matter of when she feels ready."

A strange situation unfolded late Thursday evening outside of the house where Nancy Guthrie was abducted earlier this month ... when a man was arrested for a reported DUI.

NewsNation’s Brian Entin reported the man drove slowly past Nancy’s Tucson-area home Thursday night “50 to 100 times” before being questioned by a photographer, who alleges to have seen a photo of Nancy on the individual’s phone. Finding this strange, the photog notified Pima County sheriff’s deputies, who spoke to the man for a significant amount of time.

Entin reports they had the individual step out of the car and take a field sobriety test. Apparently, he did not perform well because it appears law enforcement arrested the man on the spot.

3:37 PM PT -- A source connected to the investigation tells TMZ ... the FBI has looked at the video and says it's a dead end ... the area where the cars are driving as well as the ingress and egress has led the Agency to the conclusion the cars have no association with the kidnapping.

Update in the Nancy Guthrie kidnapping case ... a never-before-seen video has surfaced from early on the morning of Feb. 1, the day investigators believe Nancy was taken.

The video, recorded about 2.5 miles away from Nancy's Tucson, Arizona home, shows vehicles speeding by, which could lead to more clues.

Fox News reports the footage comes from a house in the Catalina Foothills neighborhood -- about 7 minutes from Nancy's house -- from a street-facing Ring camera. The property reportedly sits on a back road and avoids major intersections.

The time stamp on the video shows the footage was recorded from about 12:30 AM to 6 AM Mountain Time.

Nancy Guthrie's kidnapper was at her house before the actual kidnapping, but the photo of the presumed kidnapper has not resulted in any significant leads ... law enforcement tells TMZ, and we're told it's becoming a "cold case."

FBI sources tell TMZ ... they don't know the precise day the photo was taken, because Nancy's subscription to Nest did not include video (the videos and photos were obtained through Google), which would have provided a time stamp. Based on the FBI's broad investigation ... they believe the man could have arrived on Nancy's doorstep January 11th -- weeks before the February 1st abduction -- but they are not certain. BTW, Kash Patel said weeks ago the photo was taken the morning of her disappearance -- that is incorrect.

Our sources say neither the still photo nor the video from February 1st has helped them identify the getaway car or the suspect. As we reported, authorities have been sweeping the area for video of suspicious persons and/or vehicles, to no avail.

As for The Guthrie family's new outreach -- offering up to $1 million for information leading to the return of Nancy -- we're told the family has been thinking about making this offer for a while. In the video, Savannah acknowledges it would be a "miracle" if her mom was alive ... our sources say the FBI never told the family the chances Nancy was alive were slim ... it's something the family came to terms with on their own.

Savannah Guthrie and her family are offering a hefty reward for their missing mom, Nancy .... as part of a new plea for information.

The "Today" host posted a new video on social media stating, “Someone knows how to find our mom and bring her home.”

Savannah then admits a gut-wrenching reality ... telling fans she and her family members know Nancy may have already passed away and "gone home to the Lord that she loves."

Jesse Showalter -- the attorney for the deliveryman who was detained and later released in the Nancy Guthrie investigation -- tells Emmy-winning journalist Brian Entin his client endured at least 5 hours of questioning for no good reason.

Remember ... a man named Carlos Palazuelos -- who works for DoorDash and GLS -- was detained by authorities about 60 miles south of Tucson, Arizona. Law enforcement also questioned his family and allegedly broke down their front door while raiding their home.

Showalter tells Entin that Carlos was handcuffed in the back of a cop car for his 5-7 hour interrogation and still hasn't gotten his cell phone back from authorities.

4:19 PM PT -- Fox News reporter Matt Finn received further clarification from the Sheriff's office about this incident ... chalking this up to a "lost in translation" moment.

Pima County officials say they told the volunteers they need PERMISSION to go on private property -- not a PERMIT to look for Nancy.

1:40 PM PT -- The Pima County Sheriff's Dept posted a response to volunteer groups wishing to assist in the search for Nancy on her property. They shared a 3-part statement on X, saying ... "Private Search Parties: Volunteer search groups have inquired about being in the area. Per the Sheriff, they were asked to please give investigators the space they need to do their work."

They continue ... "We appreciate their concern, and we all want to find Nancy, but this work is best left to professionals. PCSD has volunteer opportunities if they wish to get involved with the department. Private property laws apply and it is up to each individual property owner to grant permission for someone to search their property."

The Madres Buscadoras de Sonora -- the Mexican activist group that wants to help find Nancy Guthrie -- won't be allowed to search for her, they say ... not without getting the proper permits first.

Two members of the organization -- wearing shirts and holding flyers featuring Nancy's face -- spoke to reporters outside Guthrie's home in new video circulating online. They say they came all the way from Mexico to aid in the search ... but were turned away.

Nancy left in an Uber at 5:32 PM to have dinner at her daughter Annie's house in Tucson, Arizona.

At 9:48 PM, Nancy's son-in-law, Tommaso Cioni, dropped her back off at her home. Tommaso, Annie's husband, reportedly waited 2 minutes for Nancy to get safely inside and then drove away.

A doorbell camera at Nancy's home was mysteriously disconnected at 1:47 AM. Even more distressing, Nancy's pacemaker app is disconnected from her phone by 2:28 AM.

The search to locate Nancy Guthrie's kidnapper is being looked at through a new lens ... it's not about tips or what we've seen of the abductor on camera ... it's about finding someone who fits that description -- who has been missing for 3 weeks.

Law enforcement sources connected to the investigation tell TMZ ... they want people -- especially in the Tucson area -- to think about who has gone MIA for the last 3 weeks, and there's now a fair amount of information that could help ID the kidnapper.

The man is somewhere between 5'9" and 5'10" with an average build and facial hair -- a mustache or a goatee/beard. If the ransom letters TMZ received are authentic, he's smart and very tech-savvy. Authorities believe he lives in the Tucson area.

The kidnapper has an Ozark Trail Hiker backpack, a coat we believe is an Athletic Works Fusion Knit jacket, a polyester holster, and a semi-automatic handgun.

The Guthrie family now has even more help in tracking down their missing matriarch, Nancy ... Mexican nonprofit org Madres Buscadoras de Sonora (Spanish for "Searching Mothers of Sonora") tells TMZ they've joined the effort in bringing Nancy back home.

The group's founder, Ceci Flores Armenta, tells us a reporter reached out to the organization and requested their help. Ceci says the Guthries did not contact them, contrary to reports, but she says they hope to contact the family today.

Guadalupe Trejo -- one of the moms searching in Tucson, Arizona, on behalf of the organization -- tells us ... she's been combing the terrain outside Nancy's house, with 2 other moms still on the way.

The Pima County Sheriff's Department is the subject of a hit reality TV show ... but, don't expect to see any of the Nancy Guthrie investigation featured on the show.

Here's the deal ... last year, an A&E camera crew filmed the first season of the show "Desert Law" -- currently being rolled out on the channel -- which followed deputies from the department. Sheriff Chris Nanos doesn't appear on the program.

Production sources tell us ... they have not been filming "Desert Law" during the Nancy Guthrie investigation. The show has been in the can for quite a while, and they're not looking to do reshoots.

Nancy Guthrie's kidnapper could be identified from DNA left at the crime scene in Arizona, according to Pima County Sheriff Chris Nanos.

Nanos sat down for a "TODAY" show interview Wednesday about the Guthrie case and, at one point, discussed the DNA found at Nancy's home in Tucson.

The sheriff said, "We believe we may have some DNA there that may be our suspect, but we won't know that until that DNA is separated, sorted out."

Sounds like another big swing and miss in the Nancy Guthrie investigation ... because the folks whose Arizona home was raided by a SWAT team say they have nothing to do with her abduction.

An Arizona man named Luke Daley was the subject of two search warrants issued and served Friday in relation to the Guthrie case ... according to his attorney, Chris Scileppi. For context, people online were accusing Luke of being a suspect

Luke's attorney tells TMZ Luke and his mother were both detained by law enforcement while the search warrants were being executed ... they were not arrested, Luke has no link whatsoever to Nancy, and he has no info related to her kidnapping.
