It should have been a normal Saturday evening. On 31 January, 84-year-old Nancy Guthrie had dinner and played games with her daughter Annie and son-in-law Tommaso Cioni at the couple’s house in the Catalina Foothills in Tucson, Arizona. When they called it a night, Cioni dropped his mother-in-law back at her home just a couple of miles away, waiting to make sure that she entered safely.
The following morning, though, Nancy didn’t show up to her usual church service. This wasn’t like her; friends soon got in touch with her family to raise the alarm. She was reported missing to the police that afternoon, and officers soon discovered that her doorbell camera was missing. Droplets of blood, later confirmed to be Nancy’s, were found on her front porch. Her phone and her vital heart medication had been left behind.
