Two Men Pursue $3.25 Million Claim Against Pima Sheriff in Nancy Guthrie Case

Q: Why did deputies stop and detain Carlos Palazuelos at gunpoint if no charges followed in the Nancy Guthrie investigation?

Deputies said they detained Carlos Palazuelos because they believed he was connected to the Nancy Guthrie disappearance investigation, but the public record does not show a specific lawful basis that led to charges. According to the family’s notice of claim, deputies followed Palazuelos on Feb. 10, 2026, stopped him at gunpoint, took his phone and driver’s license, and held him for seven to eight hours while they searched a Rio Rico home under a sealed warrant. Sheriff Chris Nanos also posted that a subject had been detained during a traffic stop and was being questioned in connection with the Guthrie case, and sheriff’s personnel described Palazuelos publicly as a “person of interest.” But Palazuelos was released that same day without charges, and no suspect has been publicly named in Guthrie’s disappearance. The family’s claim argues that investigators never had probable cause to believe he committed a crime and that the sealed search-warrant application relied on “false or baseless evidence.” Because the warrant remains sealed, the exact evidence investigators used to justify the stop and detention has not been disclosed publicly. So, the short answer is that deputies appear to have acted on investigative suspicion tied to the Guthrie case, but why that suspicion rose to a gunpoint stop and hours-long detention without charges remains unclear from the public record and is now central to the family’s $3.25 million claim.

Q: What was in the sealed warrant application that led to a Rio Rico home search now challenged as baseless?

It is not publicly known what was in the sealed warrant application. The reporting says only that the search of the Rio Rico home was authorized through a sealed, or secret, warrant application that remains under seal. Because of that, neither the public nor reporters have been able to review the underlying affidavit or evidence presented to the judge. What is known comes from the family’s notice of claim. Their lawyers allege the application relied on “false or baseless evidence” and that investigators did not have probable cause to believe Carlos Palazuelos had committed a crime. But the claim does not disclose the specific facts, statements, or materials that were included in the sealed filing. So at this stage, the contents of the warrant application are undisclosed, and the allegation that it was baseless remains the family’s legal claim unless the seal is lifted or the county releases more information.

$3.25 million in claims were lodged by Carlos Palazuelos and Daniel Maddox, who say Pima County deputies wrongfully detained them and damaged property during the search for Nancy Guthrie.
Palazuelos seeks $2.5 million after being detained on Feb. 10 and publicly linked to the case in a sheriff's social media post; Maddox seeks $500,000, while his mother seeks $250,000 for alleged search damage.
The filing lands as Guthrie's disappearance reaches six months with no suspects identified, despite blood spatters at her Tucson home and an investigation that authorities say remains active.
Sheriff Chris Nanos is already under pressure over his handling of the case, having denied FBI Director Kash Patel's claim that federal agents were kept out for four days.
The Guthrie family has offered a $1 million reward, and the FBI another $100,000, as investigators continue seeking a man about 5-foot-9 to 5-foot-10 with an average build.
