Betty Alexander, 69, of Sullivan, Missouri, vanished from her apartment on South Center Street after being last seen tending her garden on April 10, 2019. She was in the early stages of dementia and followed a strict routine; she did not drive and rarely walked alone. By April 11 she missed a physical therapy appointment and a Meals on Wheels delivery, and family members could not reach her for several days.

When her daughter Tonya entered the apartment on April 14, the scene raised questions. Betty’s eyeglasses were on a recliner, her purse with wallet, state ID and keys was tucked in a closet, and $200 cash in two envelopes was inside the wallet. Morning medications for April 11 were untouched, but one of two newly delivered boxes of fentanyl patches was missing. There were no clear signs of forced entry or struggle; a scratch on the screen door glass and a door found unlocked the previous Friday are noted.

Extensive searches, including K9 teams, turned up no trace. Betty’s family has kept the case public with flyers and a billboard; in late 2025 that billboard prompted a tip about someone who thought they saw her walking miles outside Sullivan on the day she disappeared, leading to a renewed search by the Missouri State Highway Patrol. Does anyone who knew Betty or was in the Sullivan area that weekend have information that could help locate her?
