Sheriff warns Nancy Guthrie suspect could 'absolutely' strike again, hints at motive

Pima County Sheriff Chris Nanos says the suspect behind Nancy Guthrie's disappearance could "absolutely" strike again, warning of a continuing public safety threat 40 days after she vanished and offering few new details about a possible motive.

"Criminal minds are criminal minds," he told NBC, where Guthrie's daughter Savannah Guthrie co-hosts the "Today" show.

Nanos said he has an idea of the motive behind Guthrie's kidnapping but declined to share it publicly.
