On June 11, 1975, Jack Jerome Girou, 49, and his wife Patricia left their Ballwin, Missouri, home and were never seen again. Their son came to the house on Father’s Day, June 17, to take them out and found the home empty but everything apparently in order: both cars in the garage, keys, wallets and money left in the bedroom, and the family dog in the backyard without food or water. Their teenage daughter JoAnne told investigators her parents left that morning to attend a funeral and that Jack had placed a .38 caliber Smith and Wesson revolver in his waistband before they departed.

She said they got into a large green limousine or Cadillac and were driven away, promising to call with a contact number that never came. Police conducted searches of nearby sewers, dug up the garden and excavated a parcel of land the couple had bought, but found no leads. Foul play is suspected and the couple has since been declared legally dead, but what happened after they left that morning remains unknown.

Did anyone in the Ballwin area recall seeing a large green limousine or Cadillac around June 11, 1975, or know more about the Girous’ movements that day?
