“How long have they been missing?” the dispatcher asked.

“Twenty minutes,” I said.

The woman was patient, but I could hear the doubt in her voice. Twenty minutes isn’t a missing person. People lose cell service. Phones die. But I knew. God help me, I knew.

Over the next few days, the panic consumed me. I drove from Tucson to Gila Bend, walked into that gas station, showed their photos to the clerk. A young man named Billy remembered them. Yes, the older man, gray hair, kind eyes. The woman, blonde, wearing a pink blouse, she’d been radiant. They paid cash for gas and two bottles of juice. Left at around 2:15. Heading west toward Yuma on the I-8.
