The neighbourhood where Nancy Guthrie went missing has breathtaking views of the Santa Catalina mountains and strict limits on outdoor lighting to protect Tucson's standing as a stargazer's paradise.
The streets of the Catalina Foothills are lined with Arizona's iconic, giant three-armed Saguaro cacti – and throngs of journalists, investigators and neighbours fixated on the disappearance of the mother of TV presenter Savannah Guthrie.
"It's unbelievable. This just doesn't happen here," said Susan Crosson, who was out for an afternoon walk with her daughter Courtney and newborn grandson.
Crosson lives around the corner from Nancy Guthrie but does not know the family.
"We're shocked," she said. "We're locking our doors."
