Pima County Sheriff Chris Nanos said his agency believes it knows the motive behind Nancy Guthrie‘s kidnapping in Arizona, warning that other residents are not immune.

“We believe we know why he did this. And we believe that it was targeted, but we can’t, we’re not 100% sure of that, and so it’d be silly to tell people, ‘Yeah, don’t worry about it, you’re not his target.’ Don’t think for a minute that because it happened to the Guthrie family, you’re safe,” Nanos said.
