Sidney Edward Johnston, 47, was last seen January 22, 1990, in Davenport, Iowa. A U.S. Navy veteran and machine operator, he lived alone in the house he had owned for 28 years and vanished the day before a scheduled court appearance on January 23 for unlawful possession of a bank identification card. Neither Johnston nor his maroon 1984 Ford Thunderbird has been seen since.

Neighbors reported an unusual pair of visitors to Johnston’s home in the months before he disappeared: a young man and woman who argued frequently with him. Neighbors also noted a change in his behavior—Johnston, previously frugal, reportedly gave away large sums of cash, up to $30,000. Police who searched his house found signs suggesting a disturbance: holes punched in the walls, a possible vomit stain on the bed, a dish of cat food left out, and unusually messy conditions. Investigators interviewed the young man and woman but there have been no charges.

The case remains open. If anyone knew Sidney Johnston, his routines, the visitors at his home, or saw the maroon 1984 Ford Thunderbird after January 22, 1990, please contact the Davenport Police Department.
