Domino’s delivery driver Susan Guy told WMC-TV that Jean Wilson has ordered pizza every day for the past three years.

On Monday, Guy said her boss told her Wilson hadn’t called in three days. Guy insisted on going to check on the woman. When no one came to the door, Guy asked a neighbor whether he’d seen Wilson and then called 911.

Police broke the door down and found Wilson on the floor. She’d fallen Saturday and couldn’t get to a phone to call for help.

Investigators said it’s possible her pizza-heavy diet may have saved her life.

Late Monday evening, Wilson was listed in non-critical condition at a hospital.
