Sheriff says he 'understands' interest in Nancy Guthrie's son-in-law

Pima County Sheriff Chris Nanos said he understands public interest in Tommaso Cioni as a potential suspect in Nancy Guthrie’s disappearance, but warned against putting a "mark on somebody who could be completely innocent." "If he is guilty, if he’s the one who did it, and we’re able to prove that, then at that time jump on it, but don’t come out of nowhere with this," Nanos said.

Cioni was the last known person to see the 84-year-old before she was reported missing on Feb. 1. Nancy had met Annie Guthrie and Cioni for dinner on the night of Jan. 31, and Cioni reportedly dropped her off at her Tucson home around 9:48 p.m. Nanos reiterated that "nobody" has been ruled out, and said he was bothered by the "nasty stuff" being speculated about Cioni.
