The investigation into the disappearance of Nancy Guthrie, the 84-year-old mother of Today co-anchor Savannah Guthrie, has taken another legal turn—this time involving a Phoenix man who says he was wrongly detained during the case.

Carlos Palazuelos has filed a notice of claim against the Pima County Sheriff’s Department, Sheriff Chris Nanos, and Detective Earl Gieron, alleging that he and members of his family were unlawfully detained during the investigation earlier this year. The filing marks the first formal legal step before a potential lawsuit against Arizona government entities.

While investigators continue searching for Nancy Guthrie months after she disappeared, the legal filing raises fresh questions about how law enforcement handled parts of the investigation and what recourse exists for individuals who believe they were wrongfully detained.

TL;DR

• Carlos Palazuelos has filed a notice of claim against the Pima County Sheriff’s Department.
• He alleges he was detained at gunpoint for seven to eight hours during the investigation into Nancy Guthrie’s disappearance.
• Two members of his family are also included in the filing.
• His attorney is seeking a formal public exoneration.
• Arizona law generally requires a notice of claim before a lawsuit can proceed against a public entity.
• The county has 60 days to respond before the claim is considered denied.

Why has Carlos Palazuelos filed a notice of claim?

According to reports, Palazuelos alleges that deputies detained him at gunpoint while investigating the disappearance of Nancy Guthrie in February.

He claims he remained in custody for approximately seven to eight hours before authorities released him without filing criminal charges.

The notice of claim also includes two of his family members, who were reportedly involved in the same incident.

Although filing a notice of claim does not automatically result in litigation, it preserves a claimant’s right to sue a government agency if a resolution cannot be reached.

What is a notice of claim under Arizona law?

A notice of claim is a legal prerequisite for many lawsuits against Arizona public entities or government employees.

Its primary purpose is to:

• Notify the government of alleged wrongdoing.
• Give officials an opportunity to investigate.
• Allow both sides to negotiate before litigation begins.
• Potentially resolve disputes without court proceedings.

In Arizona, public entities typically have 60 days to respond after receiving a notice of claim. If no settlement is reached or the claim is rejected, the claimant may pursue a lawsuit in court, subject to applicable legal deadlines.

What are Carlos Palazuelos’ allegations?

The notice of claim reportedly argues that Palazuelos was wrongfully detained despite ultimately facing no criminal charges.

According to his attorney, the consequences have extended beyond the day of the detention.

The legal filing reportedly seeks:

• Compensation for alleged damages.
• Accountability from the sheriff’s department.
• A formal public exoneration clearing Palazuelos of suspicion.

His attorney argues that the investigation has continued to affect the family months after the incident.

At this stage, these allegations remain claims made in a legal filing and have not been adjudicated in court.

How does this connect to Nancy Guthrie’s disappearance?

The detention occurred during the ongoing investigation into the disappearance of Nancy Guthrie, who vanished from her Tucson home on January 31.

Nancy Guthrie, 84, has not been located despite months of investigative work and public appeals.

Law enforcement has continued treating the case as active, with investigators asking the public for information that could help locate her.

Because the investigation remains open, authorities have released limited information regarding investigative methods or potential persons of interest.

Timeline of key events

Savannah Guthrie continues public appeals

As legal proceedings develop, Savannah Guthrie continues focusing public attention on finding her mother.

Earlier this week, the Today co-anchor shared another emotional video on Instagram asking anyone with information to contact investigators.

In the video, she described the family’s ongoing pain, saying that months after Nancy’s disappearance, they remain trapped in “a nightmare that will not end.”

She also appealed directly to anyone who may know what happened, urging them to come forward and tell investigators where to search.

These public appeals have become a recurring part of the family’s effort to generate new leads while the investigation remains active.

Why does the legal filing matter?

Notice of claim filings often receive less public attention than lawsuits, but they can significantly shape what happens next.

If the county rejects the claim—or allows the response deadline to pass without resolving it—the parties could move into civil litigation.

Should a lawsuit ultimately be filed, it could examine questions such as:

• Whether the detention complied with constitutional standards.
• Whether investigators had sufficient legal justification.
• Whether damages are appropriate if the allegations are proven.

Importantly, filing the notice does not establish wrongdoing by law enforcement. It simply initiates the legal process required before certain claims against public agencies may proceed.

What happens next?

Several outcomes remain possible over the coming weeks.

Potential next steps include:

• The county reviews the allegations.
• Officials respond within Arizona’s statutory period.
• Settlement discussions occur.
• The claim is denied or deemed denied.
• A civil lawsuit is filed in Arizona court.

Until then, both the legal dispute and the investigation into Nancy Guthrie’s disappearance continue on separate tracks.

The broader context

Cases involving missing persons often place investigators under intense pressure to pursue leads quickly.

At the same time, law enforcement agencies must balance investigative urgency with constitutional protections governing searches, questioning, and detention.

If litigation proceeds, the court process may provide greater clarity about what occurred during Palazuelos’ detention and whether investigators acted within legal boundaries.

For now, the central mystery remains unresolved: Nancy Guthrie is still missing, and authorities continue asking the public for information that could help bring answers to her family.
