Nancy Guthrie Case

The FBI has reached out to authorities in Mexico, in the hunt for Nancy Guthrie and her kidnapper, TMZ has learned ... and TMZ has received a new ransom note.

Law enforcement sources involved in the investigation tell us ... the FBI has contacted Mexican federal law enforcement to spread the word to various police agencies. We're told so far there have been no solid leads.

Our sources say the FBI believes it's possible Nancy was taken across the border, but it's unlikely it happened directly after the kidnapping. Authorities have checked Border Patrol cameras and other electronic devices, and they came up dry. That said, our sources say it's possible Nancy could have been taken across the border at some other time. Of course, there are ways to evade authorities when crossing the border.

TMZ has obtained another ransom note -- this one a highly sophisticated demand involving a cryptocurrency other than bitcoin. The email demands a dollar amount similar to the $6 million ransom demand in the previous email we received, days after the kidnapping. This email graphically describes the consequences if the ransom isn't paid.

The FBI came up dry on its DNA test of the glove found 2 miles from Nancy Guthrie's home, but TMZ has learned the agency is now doing genealogy testing, which has become a powerful tool in catching criminals.

The DNA on the glove did not get a hit from CODIS -- the database that profiles nearly 27 million people convicted of various crimes -- but genealogy testing is far broader. They're also analyzing DNA evidence found at Nancy's house.

The big companies -- 23andMe and Ancestry.com -- do not cooperate with law enforcement for privacy reasons. But smaller companies work with law enforcement, so it's another avenue for the FBI to pursue.

Savannah Guthrie's husband, Michael Feldman, landed in Tucson, Arizona today as the search for his mother-in-law, Nancy Guthrie, intensifies.

The 57-year-old PR consultant remained tight-lipped when a photog caught up with him at the airport, quickly making his way to the vehicle waiting for him.

Michael was no doubt in a hurry to reunite with his wife to add some much-needed support.

10:47 AM PT --  The Sheriff just announced there is no DNA hit from CODIS.

The glove authorities found 2 miles from Nancy Guthrie's home has been DNA tested in Florida, but there's still another step before the DNA profile can be entered in the CODIS system ... sources with direct knowledge tell TMZ.

Under federal law, the FBI cannot use the CODIS system unless the item in question is tested in the state where it was found -- in this case, Arizona. Our sources say the glove has already been sent back to Arizona. As for why the Pima County Sheriff decided to send the glove to Florida in the first place, knowing the glove would have to be re-tested in Arizona ... our sources have no idea.

We're told the type of DNA testing -- a PCR test -- typically only takes a day to get results. Our sources say the process should go quickly, and there should be results from CODIS in the next 24 hours, and maybe sooner. There are almost 27 million DNA profiles in the CODIS system.

An attorney in Milwaukee, Wisconsin is promising to cough up a $100K reward to anyone who has information that leads to an arrest in Arizona's Nancy Guthrie case.

Attorney Michael Hupy -- a prominent personal injury attorney lawyer, and president of Milwaukee Crime Stoppers -- announced the $100,000 would be offered through Crime Stoppers ... which allows tipsters to remain anonymous.

He told local channel WITI-TV he feels the anonymity may encourage people to come forward, and Crime Stoppers is the "perfect place to do it."

The Pima County Sheriff's Department in Tucson initially announced a reward of up to $2,500 for information leading to an arrest ... while the FBI's original offer was $50,000. The FBI announced Thursday the new reward was upped to $100,000.

Pima County Sheriff Chris Nanos has just confirmed all of Nancy Guthrie's family members have been cleared as possible suspects in her disappearance.

Nanos released a statement Monday, saying, "To be clear ... the Guthrie family -- to include all siblings and spouses -- has been cleared as possible suspects in this case. The family has been nothing but cooperative and gracious and are victims in this case."

He continued ... "To suggest otherwise is not only wrong, it is cruel. The Guthrie family are victims plain and simple."

TMZ has received a 4th email from the man claiming to know who kidnapped Nancy Guthrie and where she is ... and we have a proposition for that person.

The email -- with the same bitcoin account as the other 3 notes -- says in part, "I know what I saw 5 days ago south of the border and I was told to shut up so I know who he is and that was definitely Nancy with them."

This is the second reference he's made to there being more than one person involved in the purported abduction. In the third letter, received by TMZ on Friday, he said, "... be prepared to go International."

Even with Nancy Guthrie still missing, life at her Tucson, Arizona home hasn’t completely stopped ... a landscaper was just spotted showing up and getting straight to work.

A KNXV-TV journalist captured video of the worker pulling up this morning, grabbing tools from his trunk, and heading into the backyard ... walking right past a marked police car, apparently getting the green light despite the ongoing kidnapping investigation.

It’s not the first time routine maintenance has continued either ... pool cleaners were also seen at the home last week, and while it initially raised questions, Pima County Sheriff Chris Nanos told TMZ the family specifically requested the service to keep things maintained.

10:09 AM PT -- The Pima County Sheriff's Department disputed the report, saying ... "PCSD has never stated that this was a burglary gone wrong. Any reports indicating otherwise are inaccurate. This remains a very active investigation."

There’s a major new development in the Nancy Guthrie case ... authorities now reportedly believe her kidnapping may have stemmed from a burglary gone wrong.

According to AZFamily, citing an inside source, Savannah Guthrie's mother is believed to have been abducted during a botched home invasion -- instead of a carefully planned abduction.

What's more ... the source also tells the outlet there is belief among investigators that Nancy could be alive.

The theory comes on the heels of the FBI's announcement that DNA was recovered from a glove found near the scene ... the glove appears to visually match the gloves worn by the alleged perpetrator. As you know, the masked intruder was caught on a doorbell camera lurking around Nancy's home just before she was abducted on February 1.

Donald Trump is making it crystal clear ... if Nancy Guthrie’s kidnappers don’t bring her back alive, they could be staring down the ultimate punishment: the death penalty.

The President told the New York Post in a phone call the abductors need to release Nancy unharmed ... warning if she’s found dead, they’ll face "very, very severe -- the most severe" federal consequences.

When pressed on whether that meant the death penalty, Trump didn’t hesitate ... replying, "The most, yeah... that’s true."

The search for Nancy Guthrie is hitting new extremes ... members of the public are now crowdsourcing crypto, with one "concerned citizen" launching a GoFundMe to help bring her home.

The page, started by Tucson, Arizona native Shawn Breeden and titled "Help Find Nancy Guthrie," says the plan is to funnel donations straight to the Guthrie family so they can buy bitcoin ... hoping it’ll help pay for info about Nancy’s whereabouts.

As we reported, TMZ received an email Wednesday demanding 1 bitcoin in exchange for the alleged kidnapper’s identity. That’s no small ask -- a single bitcoin is currently worth about $65,000.

Pima County Sheriff Chris Nanos isn't taking any crap from people criticizing how he and his investigators are handling the Nancy Guthrie kidnapping.

On Sunday, Nanos was interviewed by a Daily Mail reporter about the case and, at one point, their convo turned to the sheriff's critics, who have slammed him and his detectives for allegedly packing up and leaving the crime scene early.

But Nanos stood his ground, insisting his officers thoroughly investigated Guthrie's property and he feels confident they did their job properly before the FBI swooped in and did another sweep.

The sheriff noted, "My officers were there for almost 20 hours, and they processed their scene, got it done, and brought in all the evidence." Nanos then said the FBI came in and "did their thing."

Authorities are using advanced Bluetooth detection technology as part of the search for Nancy Guthrie, who has been missing for two weeks.

A Pima County Sheriff's Department helicopter has been flying in a low, methodical grid pattern over the Tucson area near Guthrie’s home in an effort to detect a signal from her pacemaker, according to Fox News. Investigators are using specialized equipment capable of identifying nearby Bluetooth-enabled devices.

Guthrie was last seen around 9:30 PM on January 31 and was reported missing February 1. According to reports, her pacemaker disconnected from its companion phone app shortly before 2 AM on February 1. Around the same time, her Nest home security camera also went offline.

The investigation into Nancy Guthrie's case just took a major forensic turn ... TMZ has confirmed.

An FBI spokesperson tells TMZ ... a glove recovered in the case appears to visually match the gloves worn by the unidentified subject captured on the security camera footage released from Nancy's front door camera ... and DNA found inside the glove has been sent for analysis.

According to the feds, investigators collected roughly 16 gloves scattered around areas near the house. But authorities say most of those belonged to volunteer searchers who tossed them aside while combing the neighborhood.

Nancy Guthrie could be found one hour from now ... or it could take weeks ... or even years to locate her.

Pima County Sheriff Chris Nanos made the sobering remarks in a recent interview with the New York Times, underscoring the very real possibility Nancy's kidnapping case could drag on for quite some time.

But Nanos also assured the public that investigators will ultimately "find" the suspect, or suspects, responsible for abducting Nancy from her Tucson, Arizona, home in the wee hours of February 1.

Nancy Guthrie's kidnapper has eluded authorities for 2 weeks, but the ransom note TMZ received is of intense interest to the FBI, and Harvey Levin and Mark Geragos both agree ... it may be the key to cracking the case.

H&M's latest "2 Angry Men" podcast makes it clear ... the FBI is laser focused on that ransom letter, for reasons we cannot publicly discuss. They are also interested in the man who has sent TMZ 3 demand emails asking for bitcoin in return for giving up the kidnapper's name. BTW ... the man says the kidnapper is the "main individual" -- meaning there's more than one person involved.

Law enforcement's dramatic move Friday night apparently did not yield results, but there are a number of clues, including unknown DNA found in Nancy's house. It's currently being analyzed.
