In late summer 1964, 28-year-old Mildred Jesse Patricia Zentner and her two-year-old daughter, Patricia Louise Zentner, vanished from their Garden City, Michigan home. They were last seen August 28, 1964. The only detailed account of that day comes from Mildred’s husband and the child’s father, Jesse Zentner Jr., who said an argument began after he spanked Patricia, that he left the house and returned to find both gone. Clothing was reportedly left behind, though a few items including Patricia’s potty chair were missing, and Jesse said he tore up a typewritten note from Mildred. No official report was filed for two weeks; Mildred’s parents learned of the disappearance only after Jesse traveled to Pennsylvania to ask them if they had seen his wife and daughter, and then reported them missing.

The initial inquiry produced little, and the case grew cold. The family continued seeking answers: Mildred’s parents died in the 1980s without resolution, and her sister kept searching. In 2004 the Garden City Police Department reopened the investigation and conducted an excavation at the former family home on the 1200 block of Deering, but found no evidence connected to the case. Jesse Zentner later moved to Florida and died in 2007. Mildred and Patricia remain endangered missing with no confirmed sightings or contact since August 28, 1964.
