A man detained during the frantic search for Nancy Guthrie has launched a scathing attack on the Pima County Sheriff's Department, threatening legal action over his 'traumatic' treatment.

Luke Daley, who was held for questioning following a SWAT raid on his home, claims he was targeted without evidence due to a supposed resemblance to FBI surveillance footage.

Police have spent more than a month searching tirelessly for the mother ofTodaypresenter Savannah Guthrie as the hunt for Nancy Guthrie continues. The lack of any solid leads or signs of her location has undoubtedly made this an agonising period of uncertainty for her loved ones.

These developments come as fresh reports suggest that Daley, previously questioned in the investigation, is preparing to file a lawsuit against Pima County Sheriff Chris Nanos.

The investigation has taken many unexpected turns since the 84-year-old vanished from her Arizona home on 1 February 2026. While police have questioned various individuals, they have yet to find any definitive clues regarding Nancy's location.

Daley has already lashed out at Pima County Sheriff Chris Nanos over the way he was interrogated, according to reports. Speaking with True Crime Arizona, Daley maintained that he had 'nothing to do' with the investigation and accused the department of using the interview as a 'fishing expedition to get me to say something.'

Reports also suggest that the search for Nancy Guthrie even led investigators to question Luke's 77-year-old mother.

Although Daley and his mother were let go after only a few hours, recent claims indicate that Daley may be preparing a lawsuit against Pima County Sheriff Chris Nanos over their treatment during the investigation.

On Monday, 9 March 2026, social media reporter Jonathan Lee Riches suggested that legal action against the department could be imminent. Despite these reports, Daley himself has not yet confirmed a formal intent to sue the Sheriff.
