Fran took the call, which came from a 911 emergency dispatch operator. "Are you OK?" the voice asked. "Is anyone being attacked in your house?"

Fran didn't quite know what to make of the bizarre call, and the operator kept talking, in rather pleasant tones. "I need to let you know that you are about to have a SWAT team come to your home," the voice said, "and they're going to ask you to leave." 

When Fran poked her head out the door of her Santa Barbara home, she found the building surrounded by police, and a helicopter buzzing in the air above. It was just days after a disturbed young man named Elliot Rodger had killed six people near Santa Barbara's University of California campus and the police were especially concerned. The cops yelled at her to drop her telephone and come out onto the lawn, and that's what she did, leaving her disabled husband, her son Jason, and the nurse in house behind her.

The police eventually cleared the building, and Hal Finney, a noted computer cryptography expert, waited on the lawn for a half hour, shivering in the morning air. Fran worried that Hal, who was unable to swallow, might choke on his own saliva. "I was just panicking that he was going to need suction or something," she says. "He didn't have anything with him except his ventilator."
