Pima County Sheriff Chris Nanos has insisted investigators are closing in on a suspect in the disappearance of 84‑year‑old Nancy Guthrie in Tucson, Arizona, more than 100 days after she vanished from her home in the Catalina Foothills. In a fresh update, the sheriff said he believes 'we will make an arrest' in the high‑profile case, even as he admitted his office is deliberatelywithholding information from the public to 'protect our case'.

For context, Nancy Guthrie, mother ofTodayshow co‑anchor Savannah Guthrie, was reported missing on 1 February from her long‑time home north of Tucson. The night before, security footage is said to have captured a masked figure on her porch tampering with a doorbell camera. Blood was reportedly found on the porch, and investigators quickly concluded she had likely been abducted.

A Bitcoin ransom demand followed, the family put up a $1 million reward, and the FBI later added a $100,000 incentive. More than three months on, there has been no arrest and no confirmed sighting.

Speaking to local stationKOLD News 13on Monday, 11 May,Sheriff Nanos stressed that his department, working with the FBI, is still actively pursuing leads.

'I believe, at some point in time, we will make an arrest on this case,' he said. 'And whoever that individual is, that individual will have a right to a fair and impartial trial.'

He added that his office and federal agents were 'not going to give up on it just because it's been 100 days.'

Pressed on whether key information was being kept from the public, Nanos did not hedge.

'Yes, absolutely there are,' he replied. 'But it's not done because we gotta keep it secret. It's done because we've got to protect our case.'

That tension between public transparency and investigative secrecy has become a defining feature of the Nancy Guthrie case. Families and neighbours want regular, detailed briefings. Detectives, unsurprisingly, do not.
