Landscape crews put up ‘No Trespassing’ signs outside Nancy Guthrie’s home

TUCSON, Ariz. (NBC, KYMA) - On the heels of another emotional plea from Savannah Guthrie on the whereabouts of her missing 84-year-old mother, new signs are going up at Nancy Guthrie's home.

While the outpouring of flowers and cards continues, a series of warnings were placed among them.

Landscape crews were at the Tucson home Tuesday morning, installing several "No Trespassing" signs around the property line.

Authorities warned volunteers and civilian search parties to stay off the property after several unauthorized crews reported finding items nearby.

The signs are a reminder to the media and well-wishers to keep their distance.
